PVE Unable to access vm disks after restart

[Froto]

Hi,
So after restarting my PVE Box I notice that all my VMs and CTs on my LVM-Thin Storage cannot start.
I believe it may be because the storage device is not present. I say this because when I tried to backup my VM/CTs, It gave me this error.

INFO: creating archive '/mnt/pve/backups/dump/vzdump-lxc-230-2018_09_30-16_29_12.tar'
umount: /mnt/vzsnap0/: not mounted
command 'umount -l -d /mnt/vzsnap0/' failed: exit code 32
ERROR: Backup of VM 230 failed - failed to get device path

The storage is setup as LVM-Thin and this is lvs output

I'm new to PVE and always eager to learn. Any feedback would be very much appreciated

Thanks,

Solved(partially):
Turns out - I don't know the reason why - the lv partition was inactive
