disks are missing

coffeemachine · Oct 15, 2023

hi community,

I could use your help, my virtualized TrueNAS (Core 13.0 U5.3) can't find its data pool anymore.
The basic system is IPFire 2.27-C180, virtualized with qemu and virsh.
After a reboot via the webinterface of TrueNAS the very long waiting process aroused my interest.
The output of dmesg can be seen here:

In the configuration itself I could not find any error, which of course does not mean here may be something wrong?
All other machines run so far without problems, but have no direct access to "/dev/xyz" devices.

Now I have started a live system to exclude that the configuration of the machine is completely wrong. In this case I used "gparted-live" which showed me after the start all drives available and functional, even the underlying file systems are recognized.

through the host system I have looked at the SMART values of all hard disks, these show me no further abnormalities, that all 3 disks at the same time destroy themselves I consider unlikely.

Now the big question is still, how do I get my data pool back, and whats this 'root mount waiting for cam' in my case?
