ZFS pool imported successfully but proxmox dont see it

[doman18]

Recently i moved from pair of 500GB to pair of 1000GB. This is how i did it.

ZFSpool - name of my old pool
ZFSpool1 - name of ma new pool

zfs snapshot ZFSpool@now
zpool create ZFSpool1 /dev/sdc /dev/sdd
zfs send ZFSpool@now | zfs receive ZFSpool1@now

in proxmox GUI i deleted storage ZFSpool. Imported ZFSpool1 as ZFSpool and at this moment everything worked fine - ive seen data both in CLI and GUI. But i noticed that i forgot to add MIRROR at new pool creation, so i destroyed pool and remade it again. I did the same, but this time, when i imported ZFSpool and added storage in GUI i found that nothing is there (in gui CONTENT list) and my containers which have their volumes on this storage didnt start. But storage in CLI looks fine ...

please include your /etc/pve/storage.cfg contents and 'pveversion -v' output.

When i return to home i will get these data. But meanwhile, i just deleted my containers and recover them again from backups. And what is weird, their base volumes instead of old subvol-ID-disk-1 names have now subvol-ID-disk-0 (zero instead one at the end). I checked before recovery and im 100% sure that containers in their configs had 1 at the end of volumes, so they should point to /ZFSpool/subvol-ID-disk-1 correctly.

Also, each container had some mountpoints (mp0, mp1) binded to folders in /ZFSpool directory. I was afraid that if proxmox doesnt see /ZFSpool entirely so even though i will recover containers with their volumes from backups, there will be still problem with those binds. But, containers DO SEE /ZFSpool directory and after recovery all mountpoints pointing to it, work without a problem.
