Good evening,

first of all, i m a noob and english is not my first language. Excuse me please.

my unraid server worked sucessfully for around 55 days without any issue. as one docker app i used immich. I realized that it didnt worked anymore and i could not get any access to my database. As i opened my dashboard of the server i saw, that i hadnt any vm or docker running and that my cache drive was missing.

First i updated my server to 7.14 but it didnt work

I hope any one can help me. I attached a screenshot and the diagnostics

Any help is appreciated

Looks like the cache disk died and the disk is dead. It needs to be replaced.

Please click cache
and check smart and do a disk test:



run a SMART short self test.

I did that and it completed without an error.

Any way, is there a way to get my data (Docker and VMs) back?

Had this happen on some of my disks when i experienced a crash while it was writing to the disk. If it was an XFS filesystem try this: Data recovery | Unraid Docs

thanks for the reply, the server didnt crash and filesystem is btrfs.

USB problems, note that USB is not recomend fpr array or pool devices, but try a different USB port, then reoot and post new diags after array start

Thank you, it worked! i use a thin client "Dell Wyse 5070". So for now, i think my only option is usb...

If it keeps dropping, you can also try disabling UASP and using the old USB storage driver, UASP is faster and supports TRIM, but it's not as stable as the old one in some systems.

If you want to try that later, post here the output from lsusb -vt
