Hi Ravishankar,
I am not referring to the arbiter volume(which is showing 0% usage). I
am referring to the other 2 volumes which are replicas and should have
the exact same data. Checking the status of other bricks in ovirt
(bricks used from iso and export domain) I see that they all report
same usage of data on the data volumes, except the "vms" volume used
for storing vms.
Ah, okay. Some of the things that can cause a variation in disk usage:
- Pending self-heals in gluster (check if `gluster volume heal <volname>
info` doesn't show any entries. Also if there is anything under
`.glusterfs/landfill` folder of the bricks).
- XFS speculative preallocation
- Possibly some bug in self-healing of sparse files by gluster (although
we fixed known bugs a long time back in this area).

Ravi
Thanx,
Alex

Hi all,
I have replica 3 with 1 arbiter.
When checking the gluster volume bricks they are reported as
using different space, as per attached. How come they use
different space? One would expect to use exactly the same space
since they are replica.
The 3rd brick (arbiter ) only holds meta data, so it would not
consume as much space as the other 2 data bricks. So what you are
seeing is expected behaviour.
