Hello everyone,

I have a problem that happen twice on the same drive now. Out of nowhere, I would see in my vm that the drive is not writable anymore. I can still access my files (it's a camera software so can play archive video) but no new recording occur. In unraid, it show invalid path when I try to browse

It's a disk part of a pool, it's a single drive pool. It used to be btrfs. When it failed last time, I decided to reformat into XFS. Well, it happened again.

Ran a smart long test, no error. Last time, I also changed it's sata cable (connected to an HBA card). Smarts data look OK

I've attached a diagnostic. Wondering what is going on. Do I have a dude drive? Is it because it's attached to a VM using virtio and it corrupt it (I remember in the past, this wasn't very supported)?

Thank you

edit: I started in maintenance mode and ran a XFS check, file system corruption detected. But when I press fix it, it says it's busy

edit 2: It crashed my server. Had error on the monitor and WebGUI was dead. I did ctrl+alt+del to force a reboot which worked. Now it's back up and the file system is mounted properly. I don't understand what's going on...

And now, it doesn't show as corrupted anymore...

There's a problem with that disk, looks more like a power/connection issue. Replace/swap both cables and try again.

I'll swap again both cable then. Thanks
