Comment 12 SATHEESARAN 2021-07-22 10:49:01 UTC

Verified with RHGS 3.5.4 interim build ( glusterfs-6.0-59.el8rhgs ) with the steps from comment0

The steps created a replica 3 volume, fuse mounted that volume, then created few sparse file,
then added 3 more bricks and triggered rebalance.
Rebalance operation was successful, as queried from gluster CLI rebalance status command,
and there are no 'ERROR' messages seen either in fuse mount logs or in brick logs.

Repeated the test with sharding turned on and there are no issues seen.

Also observed that there are no ERROR messages logged in /var/log/glusterfs/*rebalance.log as well.
