[DRBD-user] Troubles with Linstor on Proxmox/ZFS

[Massimo De Nadal]

Hi,
I'm having some problems with Linstor on a Proxmox ZFS pool.
First strange think is this:

LINSTOR ==> storage-pool list
+-------------------------------------------------------------------------------------------------+
| StoragePool | Node     | Driver   | PoolName | FreeCapacity | TotalCapacity | SupportsSnapshots |
|-------------------------------------------------------------------------------------------------|
| tank        | pve-DEV1 | ZFS_THIN | tank     |     6.33 PiB |      7.25 PiB | true              |
| tank        | pve-DEV2 | ZFS_THIN | tank     |     6.30 PiB |      7.25 PiB | true              |
+-------------------------------------------------------------------------------------------------+

Obviously I don't own an 8 Petabytes pool!!

 # zpool list
NAME   SIZE  ALLOC   FREE  EXPANDSZ   FRAG    CAP  DEDUP  HEALTH  ALTROOT
tank  7.25T   706G  6.56T         -     5%     9%  1.00x  ONLINE  -

Second problem:
LINSTOR ==> resource create drbd-600-disk-0 --auto-place 2 --storage-pool tank
SUCCESS:
Description:
    Resource 'drbd-600-disk-0' successfully autoplaced on 2 nodes
Details:
    Used storage pool: 'tank'
    Used nodes: 'pve-DEV1', 'pve-DEV2'
ERROR:
Description:
    (Node: 'pve-DEV2') Preparing resources for layer StorageLayer failed
Details:
    External command used to query logical volume info: zfs list -H -p -o name,used,volsize,type -t volume,snapshot
ERROR:
Description:
    (Node: 'pve-DEV1') Preparing resources for layer StorageLayer failed
Details:
    External command used to query logical volume info: zfs list -H -p -o name,used,volsize,type -t volume,snapshot


Seems like linstor had trouble invoking ZFS commands on controllers.

Is really ZFS supported on Proxmox as Linstor backend ??

Thank you.
