[Gluster-users] Extra work in gluster volume rebalance and odd reporting

[Joel Young]

Folks,

With gluster 1.4.0 on fedora 19:

I have a four node gluster peer group (ir0, ir1, ir2, ir3).  I've got
two distributed filesystems on the cluster.

One (work) distributed with bricks on ir0, ir1, and ir2.  The other
(home) replicated and distributed with replication across the
distribution pairs (ir0, ir3) and (ir1, ir2).

When doing a gluster volume rebalance home start and gluster volume
rebalance work start, it does rebalance operations on every node in
the peer group.  For work, it ran a rebalance on ir3 even though there
is no brick on ir3.  For home, it ran a rebalance on ir1 and ir3 and
did no work on those.

[root at ir0]# gluster volume rebalance home status; gluster volume
rebalance work status

Sometimes I would get:

volume rebalance: work: success:
[root at ir0 ghenders]# gluster volume rebalance home status; gluster
volume rebalance work status

Where it only reports progress on one node.

Should I file bugs on these?
