I'm having some problems with Linstor on a Proxmox ZFS pool.<br>
First strange think is this:<br>
<br>
LINSTOR ==> storage-pool list<br>
+-------------------------------------------------------------------------------------------------+<br>
| StoragePool | Node | Driver | PoolName | FreeCapacity | TotalCapacity | SupportsSnapshots |<br>
|-------------------------------------------------------------------------------------------------|<br>
| tank | pve-DEV1 | ZFS_THIN | tank | 6.33 PiB | 7.25 PiB | true |<br>
| tank | pve-DEV2 | ZFS_THIN | tank | 6.30 PiB | 7.25 PiB | true |<br>
+-------------------------------------------------------------------------------------------------+<br>
<br>
Obviously I don't own an 8 Petabytes pool!!<br>
<br>
# zpool list<br>
NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT<br>
tank 7.25T 706G 6.56T - 5% 9% 1.00x ONLINE -<br>
<br>
Second problem:<br>
LINSTOR ==> resource create drbd-600-disk-0 --auto-place 2 --storage-pool tank<br>
SUCCESS:<br>
Description:<br>
Resource 'drbd-600-disk-0' successfully autoplaced on 2 nodes<br>
Details:<br>
Used storage pool: 'tank'<br>
Used nodes: 'pve-DEV1', 'pve-DEV2'<br>
ERROR:<br>
Description:<br>
(Node: 'pve-DEV2') Preparing resources for layer StorageLayer failed<br>
Details:<br>
External command used to query logical volume info: zfs list -H -p -o name,used,volsize,type -t volume,snapshot<br>
ERROR:<br>
Description:<br>

<br>
<br>
Seems like linstor had trouble invoking ZFS commands on controllers.<br>
<br>
Is really ZFS supported on Proxmox as Linstor backend ??<br>
<br>
Thank you.<br>

</blockquote></div><br clear="all"><div>Hello,</div><div><br></div><div>regarding your impressively large
storage pool - you are correct, linstor is missing a division by 1024. I
already found the issue and fixed it. I also found and fixed some other
(hopefully unrelated) bugs within the ZfsProvider class. <br></div><div><br></div><div>However,
regarding your second issue, from what I see without the full
ErrorReport the mentioned external command returned something that could
not be parsed as a number. That is likely something like a '-' instead
of a number in the output table of 'zfs list ...'.</div><div>Can you please run that 'zfs list -H -p -o name,used,volsize,type -t volume,snapshot' command on pve-DEV1 and pve-DEV2 and see if there is something suspicious? <br></div><div>Otherwise
feel free to send me the ErrorReport from that failed 'resource create ...' command, or what might be better is to simply open a ticket
in <a href="https://github.com/LINBIT/linstor-server/issues">https://github.com/LINBIT/linstor-server/issues</a> and attach the
ErrorReport there.</div><div><br></div><div>Thank you for reporting and sorry for the inconvenience.</div><div><br></div><div>Best regards,</div><div>Gabor</div></div>
