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