Hi all.

I have Proxmox PVE 9.0.10 and created a ZFS pool using one disk connected via SATA. Proxmox is running on bare metal.

The Pool was then passed through to an LXC as a Mount Point. Everything was fine until I a power cut and now the pool is missing. I've done some googling and the usual things aren't working.

The status currently shows up as "unknown" in the UI.

lsblk shows the disk (no partitions but this normal based on my reading)
Code: 
root@proxmox:~# lsblk
NAME                         MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda                            8:0    0   3.6T  0 disk

The disk is correct when I list by id:
Code: 
ls -l /dev/disk/by-id/ata-WDC_WD43PURZ-74BWPY0_WD-WX42D53460DE
lrwxrwxrwx 1 root root 9 Nov  4 14:33 /dev/disk/by-id/ata-WDC_WD43PURZ-74BWPY0_WD-WX42D53460DE -> ../../sda


zpool status -v and zpool list both say no pools available

The services are not all started, which I've seen in many posts online.
Code: 
# systemctl status zfs-import-cache.service zfs-import-scan.service zfs-import.target zfs-import.service
○ zfs-import-cache.service - Import ZFS pools by cache file
     Loaded: loaded (/usr/lib/systemd/system/zfs-import-cache.service; disabled; preset: enabled)

Nov 04 14:33:18 proxmox systemd[1]: Reached target zfs-import.target - ZFS pool import target.

○ zfs-import.service
     Loaded: masked (Reason: Unit zfs-import.service is masked.)
     Active: inactive (dead)

I have a (fairly small) cache file from when the pool was created
Code: 
# ls -lh /etc/zfs/zpool.cache
-rw-r--r-- 1 root root 1.5K Oct 14 20:48 /etc/zfs/zpool.cache

Importing fails too
Code: 
# zpool import -d /dev/disk/by-id/ata-WDC_WD43PURZ-74BWPY0_WD-WX42D53460DE cctv
cannot import 'cctv': no such pool available

Any ideas on what to try next are appreciated!

Hi.
Are you sure this is the disk which had ZFS?
For instance, the disk which I created ZFS on, has two very distinctive partitions:

Code: 
sdb                            8:16   0 931.5G  0 disk
|-sdb1                         8:17   0 931.5G  0 part
`-sdb9                         8:25   0     8M  0 part
