Hello guys, how are you all doing?

I am new to proxmox a total newbie, now faced with an issue of recovering vms from an about to die hard drive.

fdisk output is shown below,

What I see is the datacenter has set up proxmox fresh on linux lvm and not zfs now. So what I am thinking is,

a) Create the vms i have 5 of them from 100-105 with same disk sizes
b) Replace their storage file from backup

First of all is this the way to proceed? Now I have to mount the zfs file system. I tried installing zfs-fuse and on doing an zpool import this is what it gave,

Code: 
root@server2:~# zpool import
  pool: rpool
    id: 6734591596441369383
 state: UNAVAIL
status: The pool is formatted using an incompatible version.
action: The pool cannot be imported.  Access the pool on a system running newer
        software, or recreate the pool from backup.
   see: 
config:

        rpool                                                            UNAVAIL  newer version
          mirror-0                                                       DEGRADED
            17620338933240927984                                         UNAVAIL  corrupted data
            disk/by-id/ata-WDC_WD2003FZEX-00SRLA0_WD-WMC6N0E0TX6T-part2  ONLINE

How do I go about it? Looking for expert opinion. thanks in advance.
 
An update:

I installed the xfs utilities by running,
apt-get install zfsutils zfs-initramfs

Now the server shows the following:
Code: 
root@server2:~# zfs list
NAME                       USED  AVAIL  REFER  MOUNTPOINT
rpool                     14.8G  1.74T   104K  /rpool
rpool/ROOT                1.86G  1.74T    96K  /rpool/ROOT
rpool/ROOT/pve-1          1.86G  1.74T  1.86G  /
rpool/data                4.41G  1.74T    96K  /rpool/data
rpool/data/vm-300-disk-1  4.41G  1.74T  4.41G  -
rpool/swap                8.50G  1.75T    56K  -

But for zpool import its showing error
Code: 
root@server2:~# zpool import
zpool: symbol lookup error: zpool: undefined symbol: zpool_get_prop_literal

Any idea where to go from here? Not sure why zlist command works and not zpool.

The server was rebooted to see whether its a kernel module load issue, and its booted into a mode that appears to be single user. No settings or changes were made manually to the bootloader. Can someone help please/ How to reinitialise proxmox without a reinstall to its original state. More like a reset.
