Possibly. I don't think changing shard size on the fly is supported,
especially when there are files on the volume that are sharded with a
different size.

The heal status is showing that no pending files need healing (also
shown at GUI).
When checking the bricks on the file system I see that what is
different between the server is the .shard folder of the volume. One
server reports 835GB while the other 1.1 TB.
I recall to have changed the shard size at some point from 4 MB to 64MB.
Could this be the cause?
Thanx,

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).

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.
