Also I see:

/var/log/glusterfs/img-rebalance.log-20150430
[2015-04-29 14:49:40.793369] E [dht-rebalance.c:1515:gf_defrag_fix_layout] 0-img-dht: Fix layout failed for /www/thumbs
[2015-04-29 14:49:40.793625] E [dht-rebalance.c:1515:gf_defrag_fix_layout] 0-img-dht: Fix layout failed for /www

Have you recently run a rebalance?  Are you having trouble access those directories?  It looks like the fix layout failed for those two.
