Can you provide the output of gluster volume info before the remove-brick was done. It's not clear if you were reducing the replica count or removing a replica subvolume.

Hi.
There is an ovirt-hosted-engine on gluster volume engine
Replicate replica count 3

Migrate to other drives.
I do:
gluster volume add-brick engine clemens:/gluster-bricks/engine tiberius:/gluster-bricks/engine octavius:/gluster-bricks/engine force
volume add-brick: success

gluster volume remove-brick engine tiberius:/engine/datastore clemens:/engine/datastore octavius:/engine/datastore start

Can you give some advice?
