FSLogix suddenly loses connection to all profiles

Has anyone seen this? 

3 hosts in a host pool with FSLogix profiles in AD-joined Azure Files. Working fine for years. Suddenly, mid afternoon while people are signed into all 3 hosts, the connection to the profile disks is gone. Subsequent sign-ins have FSLogix error: 


The user profile failed to attach. Please contact support. 
Profiles 
Status: 0x0000001B, Message: Cannot find virtual disk at the provided location
Reason: 0x00000005, Message: Reason initialized to empty state 
Error code: 0x00000005, Message: Access is denied. 

The share looks fine from the Azure portal, and I mapped a drive to it from one of the hosts, using the storage key. NTFS permissions look right. 

We have a ticket with Microsoft support, and I'm really wishing we had Nerdio Enhanced Support. I'm pushing for that.

Hey, Peter. 🙂
Correct, if you're using Active Directory joined hosts and Active Directory joined file shares, the user accounts (and/or groups) need to be sync'd from the domain to Entra using Entra Connect.

The issue you're facing makes it sound like something may be scanning/locking the profile disks and preventing users from logging-in. Do you know if you have Microsoft's recommended Antivirus file and folder exclusions for FSLogix in-place with your tools?

Hi Dave, we don't have AV on there at the moment. We removed the AD sync over a week ago, and put it back, but still no good. We're going to install a new host pool; we wanted to move to premium storage anyway. This was our first internal FSLogix pool, and we put it in Standard storage to “see how it is”. Due to transaction costs, Premium would actually cost less, aside from the performance. 

We are signing up for Enhanced Support, so you may not have heard the last of this. :)

Haha. That'll be great!
We'd love to help you out with that.
Not to brag, but our Enhanced Support team is pretty awesome! 🤩

Moving profiles is fairly painless (see Moving Profiles to a new Storage Account – Nerdio Help Center), but I don't think it will make much difference on the issue you're seeing.
We'll likely need to dig-in to the logs to figure out what's causing it.
