[Gluster-users] geo-replication issues/questions

[Vijaykumar Koppad]

hi Matthew ,

   This is weird. There might be some inconsistency between gsyncd and glusterd communication. 
Just try restarting glusterd once. If it doesn't work, I guess we need some more info 
on what all you did before this happened.

Thanks,
Vijaykumar
