failed to start import zfs pool rpool

[Ldmit]

the system is installed on an ext4 ssd disk, and there are also two disks in the raid on zfs. When booting the system, an error popped up: failed to start import zfs pool rpool

You could try to boot from a PVE iso into rescue mode to look why it can't import your pool. Output of a failed zpool import rpool command would be useful.

Did it worked fine before?
Did you change anything?
Did you encounter a power outage?
Was your rpool a mirror (like raid1) or a stripe (like raid0)?

You could also run a smart test on your both disks to see if the disks got any problems.

All work, the backup on ftp hung, I decided to restart the server for prevention and everything fell.
The server is located in the Data Center.

connected zfs pool in read-only mode, how to copy lvm disks from it and transfer it to another server?

 

[Dunuin]

LVM disks? You can copy zvols and datasets between pools by using replication. Google for "zfs send |zfs receive". By piping that to SSH you can even copy zvols and datasets across the internet between different servers.
But you need a snapshot for that, so not great if that pool is read only with recent spanshots missing.

tell me how to convert disk.raw for LCX?

 

[Dunuin]

LXC use datasets so they are filesystem based and not block based like zvols VMs use.
