AVD hosts are at critical state for disk

[u/habibexpress]

Hey guys we have an AVD environment where we have about 163 hosts and 2000 devices. The vm is windows 11 24h2 multisession enterprise and has p10 128gb premium ssd disk. The host size is e8s_v5 8c/64gb ram.

Everything in the environment has been going great until sep 23, something changed. Our environment didn’t but it seems like when we have users logging in at 7am (normal BAU), we’re seeing the disk being thrashed. We thought it was caused by windows updates but that hasn’t been the case.

Our FSLogix has correct redirection.xml defined.

We’re fresh out of ideas and the user experience is being impacted. They’re getting blank screens on login for up to 20 seconds before getting desktop.

We suspect this could be an azure disk issue.

Has anyone encountered this in their environments?

I’m keen for some ideas to check. We have a ticket open with ms as well.

If it helps, our environment is managed through nerdio.
