<p dir="ltr">Are you using drbd9 with a 3 nodes replication?<br>
could you please share the drbd config? </p>
<p dir="ltr">> We use ZFS on the storages, ZVOLs on top of that, each ZVOL makes up part of the DRBD resource that gets exported to the hypervisor.</p>
<p dir="ltr">No raid volumes?<br>
are you creating a single drbd resource for each storage disk? (In example, in a server with 12 disks are you creating 12 drbd resources?)</p>
<p dir="ltr">i would like to create a raidz2 on each node but the resulting volume is not seen as block device thus can't be used as drbd resource</p>
<p dir="ltr">I can create a raid6 with mdadm, use that volume for drbd and put zfs on top of it but there are too many moving parts stacked together, that would be a perfect reciepe for a huge mess </p>
