Hello Community,
I have a problem running a snapshot of a replica 3 arbiter 1 volume.
Error:
[root@ovirt2 ~]# gluster snapshot create before-423 engine description "Before upgrade of engine from 4.2.2 to 4.2.3"
snapshot create: failed: Snapshot is supported only for thin provisioned LV. Ensure that all bricks of engine are thinly provisioned LV.
Snapshot command failed
Volume info:
Volume Name: engine
Type: Replicate
Volume ID: 30ca1cc2-f2f7-4749-9e2e-cee9d7099ded
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x (2 + 1) = 3
Transport-type: tcp
Bricks:
Brick1: ovirt1:/gluster_bricks/engine/engine
Brick2: ovirt2:/gluster_bricks/engine/engine
Brick3: ovirt3:/gluster_bricks/engine/engine (arbiter)

All bricks are on thin lvm with plenty of space, the only thing that could be causing it is that ovirt1 & ovirt2 are on /dev/gluster_vg_ssd/gluster_lv_engine , while arbiter is on /dev/gluster_vg_sda3/gluster_lv_engine.
Is that the issue ? Should I rename my brick's VG ?
If so, why there is no mentioning in the documentation ?
Best Regards,
Strahil Nikolov
