FSLogix Profile's disconnect during clustered file server failover

We are currently using FSLogix as a user profile solution. We save our profile disks to a DFS path (\\ADdomain.com\FSlogixProfiles). That DFS path points to a Microsoft Continuously Available File Server running Server 2012r2.

If we migrate the file server role from one host to another - Our VDI desktops all crash and the profile becomes disconnected. Then the users cannot get back in because the systems are all locked.

All of our other applications handle a failover without an issue. Windows 10 & SMB3 allows this failover to be transparent to the users and has never caused any issues with other applications accessing shares on this cluster.

So why is FSLogix not able to?

We have the re-attach settings as follows:
Re-AttachIntervalSeconds = 5
ReAttachRetryCount = 30

Anyone else see this behavior? Or have any suggestions to keep this from happening?

HI AGarA-2861,

1.Do you use Multiple SMB Locations with Multiple VHD Paths in your current envrionment?

2.When the disconnect issue happen, we can try to capture the fslogix log of user's fail logon

On the problematical rdsh, download the support tool from
https://aka.ms/fslogix_support_tool
1).Run the FSLogix Support Tool.
2).Fill in the company name (we use this to separate the information from others).
3).click "enable logging" and Select "Gather Rule files", and "Gather Dump Files".
4).Click "Gather FSLogix Content" ( Please note: this will take several minutes)
5).Once complete, please locate the resulting zip file from C:\ProgramData\FSLogix\Support and attach it to your support ticket.

  1. We are using a single SMB location to a clustered file server. A single VHD path. Looking at the article in the link, I see we need to make some changes possibly. But we are unable to use cloud services on these VDI roles so that isn't an option.

  2. We cannot capture the logs because when the profile becomes disconnected, the desktop becomes unresponsive. If we reboot the desktop, it rolls back to it's sysprepped state ready for a new user. So logs would be lost.

Thanks for the link to the article. That is what I need to dig deeper into and see if we can come up with a better solution than a clustered file server I guess.

Thanks.

Hi,

We were with Microsoft Scale Out Files servers and Cloud Cache on 3 locations for more than a year and had some many issues that FSLogix couldn't fix.
We recently learn from FSlogix support that they have an issue with Cluster and to use direct server name instead. It was not possible as disk could change inside the cluster anytime that we reboot a node.

We have move away from Clustering and are using dedicated servers with Cloud Cache on 3 locations and almost all our issues are now gone.

I would recommend to stop using Cluster.
