0: OneNote notebook files aren't redirected to the container. Use this setting to define how FSLogix attempts to locate a users profile container (VHD(x) file). Just getting error, that first location can not be found. 1: A difference disk is used on the network. FSLogix Profile Container is enabled by default on the Nerdio configured AVD Windows 10 multi-session template VM. Figure 1: FSLogix High Availability using Cloud Cache. 0: VHD(x) is of a fixed size and the size on disk is fully allocated. Storage wasnt an issue (this was a cloud-based deployment), but the volumes we could attach to the file servers were limited to 16TB each, and therefore we needed quite a sizeable amount of these volumes. 0: Teams data isn't redirected to the container. There may be instances where disabling this setting can improve sign-in performance, but shouldn't be a long term solution as the orphaned entries continue. We do this using type=smb,connectionString=<storageaccountshare>. Also, at sign out, if any Cloud Cache provider wasn't available the user's sign out would be prevented indefinitely. A list of SMB locations to search for the user's ODFC VHD(x) file. For more information, see. When enabled, this setting creates a redirection for the user's specific Recycle Bin into the VHD(x) container. If a user accesses a system where it's desirable to have the local cache VHD(x) deleted when they sign out, set this value to 1. Specifies the number of seconds to wait between retries when attempting to reattach the VHD(x) container if it's disconnected unexpectedly. When CcdMaxCacheSizeInMBs is set, the local cache is allowed to expand to the maximum size, at which point blocks are removed from the local cache as they're written to the remote Cloud Cache providers. Each location has its own write cache list since they may flush at different speeds. I want to make use of File On demand to give user better experience but dont want to retain data locally in the end just because it will be available on cloud as well. I will post findings at a later date. Ryan had experienced a similar problem, and his response was simply to use a PowerShell startup script to iterate through a list of file servers and order them by their free disk space. 0: Outlook data isn't redirected to the container. When setting HealthyProvidersRequiredForRegister to anything other than 0, then PreventLoginWithFailure and / or PreventLoginWithTempProfile should be used in order to create the desired user experience. Use this setting to define how FSLogix attempts to create a users profile or ODFC container folder. We've built our new WVD environment and it looked like FSLogix was the way to go. Windows Virtual Desktop (WVD) is now known as Azure Virtual Desktop (AVD), though the name of the setting uses the legacy name. Here are the steps to add a cloud cache registry key with a file share: 1. CCDLocations should be used instead of VHDLocations. If it doesnt find one, though, it is created in the first entry in the list which would be the file share with the most available space. When enabled (1) FSLogix loads the FRXShell if it's determined a temp profile has been created. All sessions trying to use the VHD concurrently must have a matching, OneDrive does not support multiple simultaneous connections / multiple concurrent connections, using the same profile, under any circumstances. Some of these entries persistent post profile deletion and may cause long term issues. Specifies a string pattern used when creating a profile or ODFC container folder. This allows for simultaneous session access. CCDLocations supports SMB and Azure Blob types with up to four remote container locations. Cloud Cache settings are only valid when used with, Requires FSLogix v2009 or later (2.9.7654.46150), 0: The user sign out is held until the number of providers specified in, 0: Retains the local cache when the storage provider is unregistered when the, 1: Removes all local cache when the storage provider is unregistered when the. We are primarily looking to make use of One Drive with roaming profiles, may it be a Non-Persistent Desktop or Terminal Server shared desktops. 2: Machine should only be the RO profile instance. Don't use the plain-text connectionString for Azure page blob storage providers. Permissions-wise, you need to make sure that you give Domain Computers (or at the very least the Citrix worker computer accounts) RX access to the root of the share so that you can determine free space. When enabled (1) this setting cleans out registry keys in the HKEY_LOCAL_MACHINE hive that refer to a users SID. In cases where a user's session terminates abruptly, the VHD(x) mounted for the user's profile isn't properly detached and the user's next sign in may not successfully attach their VHD(x) container. 3: Redirect TEMP, TMP, and INetCache to the local drive. This setting ensures cached mode is used only when the container is attached. Specifies a string pattern used when matching a users ODFC container. A list of SMB locations to search for the user's profile VHD(x) file. I am going to be doing some in-depth testing with REFS and Azure Files based replication and see how it plays. Registry Path: HKLM:\SOFTWARE\FSLogix\Profiles\, Registry Path: HKLM:\SOFTWARE\FSLogix\Profiles\ObjectSpecific\S-0-0-00-000000000-0000000000-000000000-1234\, Registry Path: HKLM:\SOFTWARE\FSLogix\Profiles\ObjectSpecific\S-0-0-00-000000000-0000000000-000000000-4321\. These registry items are orphaned entries referring to users. The ideas and concepts in these examples should inform your unique organizational requirements. As for seamless failover have you done it with CloudCache? The Advanced configuration example expands on the Standard example though introducing multiple VHDLocations OR Object-Specific settings AND minimal entries in custom profile redirections. SDDL string representing the ACLs to use when creating the profile directory. FSLogix uses the VHDLocations or CCDLocations as the location where to search and this setting defines what to search. All the 10,000 VDIs will be in same OU, how can i define multiple file shares for the users? So technically, new users would *always* hit the file share with the most available space. Make sure via Group Policy that you set policy setting Enabled to Enabled under Computer Configuration -> Administrative Templates -> FSLogix -> Profile Containers or else Office 365 Containers if you aren't redirecting the entire profile to a container. This configuration is not load balancing between the two sites, rather we're relying on users only having access to a single location. Additionally, any backup solution that does not do block-level backup can struggle to backup the open container once it is mounted and locked. The main thought was how big do we possibly expect the profile to get for each user? A new one will only be created if it does not exist on ANY of the configured file shares. Heres a diagram spelling out the process:-. When the script runs, it adjusts the Registry value so that a new user will get their profile created on the first share in the list. Implementing the solution is relatively easy. But, at least good thing that Microsoft is considering to add a feature to shrink the VDIs on attach or detach. DFS-N should always be configured in an Active-Passive methodology, ensuring that referrals and folder targets are appropriately leveraged, ensuring consistency of access and in typical useage scenarios, a supported architecture. Recently, we were asked to scale up a Citrix deployment, shall we say, rather heavily, and indeed, rather rapidly. This model also introduces a requirement for something to handle the replication of containers across both locations in a consistent fashion (more on this later). We recommend to use a separate profile container per host pool, while having two active sessions. Consider using the object-specific configuration settings in lieu of multiple VHDLocations. Is there a way to manipulate the script to do it in this way? If it doesn't find one, though, it is created in the first entry in the list - which would be the file share with the most available space. Firstly, if someone expands their profile massively they could still potentially fill the file share. Its at this sort of time that you normally turn to the community to get a different perspective, and thats where Ryan stepped in with a suggestion. When configuring any settings associated with disk register or unregister events, verify that you're familiar with the concepts, and that the configurations achieve your data integrity goals. Could this possibly be why its not detecting that it currently has a profile and do you know how we can resolve this issue? 0: VHD (x) is of a fixed size and the size on disk is fully allocated. However, the DFS namespace controls where that data lands and in which order. Simply placing a Distributed File System Namespace in front of one or many SMB locations. When enabled (1), this setting reads the AppxPackages.xml manifest file from the user's profile and installs / re-registers the list of applications. Over long periods of time duplicate OST files may consume incremental disk space. As with any multi VHD location-based architecture, there is a requirement to replicate the containers. Dr. Amy Alias MD. 1: Machine should only be the RW profile instance. FSLogix allows for multiple paths to be defined to allow for failover should one location be unavailable. A single Profile container is created for the user. How this script can be used with Cloud cache? So with this being run, our users are directed to any one of (in this particular case) twelve file shares of 16TB each. When you ask a business if they want to pay for hundreds of terabytes of extra storage so Brian in Accounts doesnt have to reset his Outlook views and colour settings after an outage, are they going to say yes? System will need to wait till user login back satisfying 24 hr duration for One Drive cache to get cleared up. This setting isn't designed to limit the size of the local cache during failure scenarios, but is rather intended to provide predictable operation during normal operation. 1: Outlook personalization data is redirected to the container. For me, OneDrive with KFM is rapidly becoming a way to achieve this without the storage uplift. Check the box next to I agree to the license terms and conditions and click Install. There were cloud services we could have leaned towards to accommodate this, but they had not yet been cleared for usage within the environment, and were unlikely to anytime soon. Change the value to the number of seconds a user's sign out is delayed if the number of available providers is less than the value specified in HealthyProvidersRequiredForUnregister. Essentially, as long as the script was run often enough for the volume of new user onboarding, the profiles would be load balanced across the file shares. An upgrade install will leave all logging settings as they exist before the upgrade install. Major version of the operating systems as seen in: Minor version of the operating systems as seen in: Build version of the operating systems as seen in: Legacy to Windows service packs, no longer used. Setting the value to 0 may cause the permanent deletion of the user session data stored in the local cache, without the protections built in through CcdUnregisterTimeout and ClearCacheOnForcedUnregister. This controls the number of session VHDs that are persistent. 3,289 Setup fails with failed to start redirector driver. For each set, the data is read from the local cache VHD(x) in the CacheDirectory then written to the CCDLocations. Choosing to use VHDLocations rather than Cloud Cache does not mean that the ability to define multiple locations is lost. Below are the FSLogix GPO settings applied to Windows 10 Golden image, which then gets deployed to 250+ VDI. Figure 3: Cloud Cache (primary / failover) | FSLogix Cloud Cache (CCDLocations). For more information, see the VHD Disk Compaction documentation. It is, however, once again, a file-based solution so will not be able to replicate mounted containers or locked files. When using this configuration setting, be sure the VHDNamePattern value matches this setting. The environment in question was already using FSLogix Profile Containers. The connectionString for smb type must include the full UNC path to the file share. 1: OneNote notebook files are redirected to the container. We have upwards of 500 on some file shares and not seeing any issues (nothing reported, anyway). You can observe that behavior looking at the profile log FSLogix documentation. To control the number of VHD(x) files that persist, see the NumSessionVHDsToKeep setting. This value specifies the location of the local cache VHD(x). FSLogix Profile Container is becoming the go-to solution when it comes to profile management. 1: VHD (x) is dynamic and only increases the size on disk as necessary. using logoff scripts etc etc, which technically worked well but had no blessings from Microsoft to support that. Multiple entries in VHDLocations doesn't provide container resiliency. Looking at OneDrive usage gave us an average of around 8-10GB so being cautious, we anticipated looking at 30-40GB per user. You can follow the same instructions mentioned in the profile container to get the file share name. The script should be run as required Startup Script would be fine if your reboot schedule means that the amount of users you are onboarding in between reboots doesnt potentially exceed the capacity of a single file share, otherwise run on a Scheduled Task. If the ODFC container is being used with Outlook cache mode. We had carved out a totally different solution to address our concern. There's no profile recovery as the user's create new profiles in the new location. For more information, see Configure Windows Search database roaming. The following settings are applicable to profile containers and are created in the following location: Do not use this configuration setting unless your storage provider or architecture will NOT work with user-level permissions to the VHD(x) container locations. FSLogix uses the VHDLocations or CCDLocations as the location where to search and this setting defines what to create. When enabled, this setting attempts to compact the VHD disk during the sign out operation and is designed to automatically decrease the Size On Disk of the user's container depending on a predefined threshold. This is the simplest access model, but only allows one concurrent session. When using FSLogix the OST file is in the container and isn't as visible. 2: Reboot when a FSLogix profile user signs out. The user receives the default prompt to call support, and the users only option is to sign out. 4096: VHD(x) is formatted using 4096 byte allocation. CCDUnregisterTimeout is set to specify the number of seconds to wait prior to allowing a user session to be closed, even if a successful flush to a Cloud Cache provider hasn't occurred. Secondly, finding a users profile when they are one of a large number of file shares is a bit annoying and takes quite a while! 1: Redirect TEMP and TMP to the local drive. When consuming containers with Azure files via either Cloud Cache or VHD locations. The COMPUTERNAME of the client initiating the connection to the host. The following post will discuss scenarios relating to HA options and considerations around replication requirements. VHD-based profile solutions such as the FSLogix Profile Container and the Citrix Profile Management profile container do not support saving changes in multi-session scenarios. The user is affected in a negative way up to and including session failures and/or data loss. 1: OneNote UWP notebook files are redirected to the container. c. Other way that was suggested was to use attrib commands to un-pin the cached files that Storage Sense cant help with, but again, this is not configurable anywhere in One Drive Client. We have set profiles to a limit of 100GB but obviously if many users suddenly underwent a huge increase we might have issues. These settings will accept the list of custom environment variables and any variables available during the user's sign in. Multiple VHDLocations Object-Specific VHDLocations The default VHDLocations is used for any user or group not matched by the object-specific configuration. If a user signs in with no available providers, FSLogix assumes that one or more Cloud Cache providers become available prior to the user signing out. The major drawback is the experience and training for end users is a critical component for success. Users only have access to a single region at a time. The type accepts either smb or azure. All the MS documentation is proclaiming the . The path supports the use of the FSLogix custom variables or any environment variables that are available to the user during the sign in process. If you want active-active HA, use cloud cache. Also, it is worth noting that the script (below) uses a Z: drive to query the free space so be careful if youre running it manually to make sure you dont have a Z: drive mapped anywhere. Because both locations are active and there is a cache capturing reads and writes in the middle, seamless failover between locations can be achieved. One subscription support only 2500 VDIs so will be using 4 different subscriptions. When the profile is stored in the standard file system, administrators may remove orphaned or stale OST files by deleting them. And, as profiles can be located in more than one location, the Value should be a Multi String value for VHDLocations Located under HKEY_LOCAL_MACHINE\SOFTWARE\FSLogix\Profiles You can see this is you run the configuration manually running the C:\Program Files\FSLogix\Apps\ConfigurationTool.exe and that's what we do. These VHD(x) files will typically persist so that they can be used the next time a user creates a session. Extract the downloaded .zip file. Dr. Amy Alias is an internist in Fullerton, CA, and is affiliated with Providence St. Jude Medical Center. And then we came to storage and oh boy, the numbers looked heavy. These containers are mounted at user logon effectively mobilising a local profile. Whoosh! Storage that is appropriate for the local cache VHD(x) will have performance and availability characteristics similar to SSD or NVMe attached storage. Option 2: Leverage VHD locations and replicate data between these locations using other solutions The next scenario is the next most common deployment I have seen, and this is simply implementing what we have traditionally done with other profile solutions to achieve active/passive access. NETBIOS domain name where the user's account resides. Next we looked at network capacity again, plenty of headroom for the expected increase. FSLogix does not limit us to defining one location in the VHDLocation pathing; however, only one location based on the order defined, read, and detected as available will be active. For our purposes this has worked very well, however there are a couple of points to be aware of. This setting is intended for situations where storage provides a location that is already unique per-user. The default VHDLocations is used for any user or group not matched by the object-specific configuration. When set to 0, users are always allowed to sign in even if no Cloud Cache providers are available. The logging is sensational and I am struggling to fault the tool so far. A single profile container is created for the user. Separate pools of virtual machines in each location. Configuring Network Shares Network shares are used to store VHD (X) files and to centralize logging information. Each example has an associated configuration focused on redundancy or disaster recovery. In some scenarios, users have expressed a desire for more granular control over these behaviors. Anytime the use of a VHDLocation is defined; we are automatically subscribing to a single active profile location methodology. Firstly, take note of the fact that the potential scope of failure has increased possibly greatly. Holly 162. 0: OneNote UWP notebook files aren't redirected to the container. This allows for simultaneous session access. Default Value: %ProgramData%\FSLogix\Logs. The best part of this solution is that it can handle block-level replication meaning that replicating mounted containers is no issue. Only one location can ever be active at one time. One Azure file share support up to 100 TB so it can handle around 2500 users with 40 GB disk each. Cloud Cache also allows for the seamless failover between multiple locations. Logging is done as SYSTEM when logging to a local drive, and as the Computer Object when logging to a network share. 0 Likes . This setting specifies the number of healthy Cloud Cache providers required to allow a sign-in. Also, local cache potentially could have given us a 300GB storage increase for each server that was deployed, and that again would be a cost implication that would be unpalatable. A former engineer built the FXlogix container on a drive that is no filling up and we can no longer grow. technical how-tos | software reviews | industry news | forthright opinions | videos | podcasts | rants and raves. This is the only operating model and is designed to utilize resources in the most efficient way possible prior to impacting the user's experience. This example removes the Object-Specific configuration as the multi-regional components adds complexity. Multi Family Home for Sale in Fullerton: Cloud Cache is not limited to Blob Storage in Azure. If it finds one, fine. Changing the location of the log file, it is required to reboot the system or restart the FSLogix Service. Depicted below is the most common and most simple deployment of the FSLogix solution. Products: Profile Containers: Put users' profile folder (\users\<username) in a VHD(x) and connect at logon to roam profiles without streaming. Verify that you understand the implications of changing the default value of this setting prior to making changes. Continuity to data has been the primary reason for developing cloud cache and with many organisations . The second option is FSLogix Cloud Cache, an emerging capability which promises the holy grail of Active-Active profile locations. '0' - Log DEBUG level messages and higher 1 - Log INFO level messages and higher 2 - Log WARN level messages and higher 3 - Log ERROR level messages and higher. So, we need to remove our GPO setting using VHD locations, and then set our CCD locations. Most profiles were in the 5-10GB mark (Teams, it would appear, throws out 4.6GB of data every time it is run for the first time, although this might have been down to an erroneous Chocolatey package), but we had some outliers around the 20GB mark, and a very small number slightly above this. e. The least time duration that we can set for a Cloud storage dehydration threshold in Storage Sense is 1 day or 24 hrs. 3: A unique VHD(x) is used for each concurrent session. Dealing with high availability and navigating the options associated with containers, however, is not a simple task, and there are a few points to look at while deciding what architecture may be best suited from an HA perspective. We have swap directory name components set so this causes new containing directories to be named with the username first followed by the SID. Defines the number of required 'healthy' storage providers necessary for a successful user sign-in. This insures if FSLogix gets disabled, that large OST files won't be downloaded. Be sure you understand how conflicting settings are applied and prioritized. To this end we are going to write an environment variable into the user profile with the name of the configured file share and display it using BGInfo to save us from this problem. No need for your startup script then! Hi Guys, we have been using UPM looking to move over to FSlogix Profile Containers. A lot of people will say why not just use Cloud Cache, but there are a number of reasons around this. Issue: VHDX profile gets DISCONNECTED at exactly 10 Hours mark. When multiple entries exist, a user will try to create or locate their container from the list of locations in order. If a user logs in with an existing profile, FSLogix simply iterates through the listed shares in the Registry value until it finds the profile. Changing this value will take effect at the next reboot. Allows unique settings based on a user or group SID. Default Value: %userprofile%\AppData\Local\Microsoft\Outlook. It is also unclear how Cloud Cache deals with a file share being at capacity as far as I know it looks for availability only, although I am open to being educated if I am mistaken. Specifies a log file name and path where the output of the robocopy commands (for example, during mirroring of data in or out of a VHD) are stored. Second is that in the past Cloud Cache has been very buggy and it is only in more recent releases that it has improved, so I was loth to hang a production environment on it based on past experience. Normal operation assumes that all Cloud Cache providers are available, and that storage performance is adequate to accept I/O at the rate necessary to accommodate profile utilization. I am going to deploy Citrix VDIs on Azure for 10,000 users. VHD location is currently set through GPO and creates the users profile inside of folder called firstinital.surname. When youre talking about adding three-figure percentages to your workloads, you need to plan for an unprecedented capacity increase. By default, the local cache VHD(x) isn't removed when the user signs out. This specifies how many to keep. So in answer to your question, no, a user with an existing profile container will always use that. This also applies if you're using multiple VHDLocations entries for failover in any way, not just if you're using the scripted method, so if you're doing it this way please read on! OneDrive does not support multiple simultaneous connections / multiple concurrent connections, using the same profile, under any circumstances. When youre talking about tens of thousands of users, this number gets very big, very quickly. The following settings are applicable to ODFC containers and are created in the following location: SDDL string representing the ACLs to use when attaching the VHD. Traditionally, Cloud Cache had rigid behavior when all defined providers weren't available at user sign-in and sign out. There is a cost to this capability, and that is an impact on Logon and Logoff times for users due to the requirement to build a local cache on the endpoint. CCDLocations are formatted using a type, name, and connectionString separated using a ; as the delimiter. Note This setting is used with the SizeInMBs setting to manage the size of profile containers. d. Even enabling Storage Sense for a computer, a user will still need to manually set the caching policy to least available 1 Day from default value of None.
