Hello there!
Thank you for reading my message.
I have six 1TB HDD and I created a raidz2 disk with all of them, which resulted in an usable capacity of 3.87TB.
They've been working fine for months but today the VM (Nextcloud) stopped working.
The SMART results on all disks are fine but the VM doesn't boot at all.

I checked the System log and I see what is shown below when I start the VM and it keeps repeating over and over again until I stop it.
Any idea what's going on?
