[Gluster-users] Ownership changed to root

[Anand Avati]

Is it possible a gluster volume rebalance (or remove brick) was in progress
in the background? If so you might have hit
http://review.gluster.org/3861. If not, can you please file a bug with the
client logs (of all the machines where 'disk' file was possibly getting
modified?

Thanks,
Avati
