Originally on bkp-01 instance. The server and disk have manually been set to a different availability zone. The disk are running zfs for backups/snapshots. It's an old server with a manual Raid system.
Now if we check :
root@bkp-01:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

A working setup for an older server (bkp-01) type should look like that:
Before the restart
root@bkp-01:/# zpool status
pool: storage
state: ONLINE
scan: scrub repaired an in 701hSflm with 0 errors on Mon Jan 9 06:14:20 2023

vde ONLINE 0 0 0
vdd ONLINE 0 0 0

vdf ONLINE 0 0 0
vdg ONLINE 0 0 0
Now if we check To check available disk space
After the server restat we have :
root@bkp-01:~# zfs list
no datasets available
root@bkp-01:~# zpool status
no pools available
This backup error are showing on the logs as :

We tried :
mount /storage/mount-revitalis
output

passfile=/root/tmp-pass-revitalis.txt
And
root@bkp-01:~# mount /storage/mount-revitalis
Attempting to mount with the following options:

Check your system logs; visit <http://ecryptfs.org/support.html>
Is this happen because of : Originally there was a ZFS pool "storage" with RAIDZ1 vdevs, After a reboot, the ZFS pool is missing entirely and This is causing backups to fail due to missing mount points?
Do Recreate the ZFS pool and Recreate the datasets will help here ?
Any help would be higly appriocate!
