Hi Lindsay, As I understand it, the current logic of bitd/scrubd does not address the problem you asked about "a process where all replicas are compared for inconsistencies." bitd/scrubd operate independently within each node, signing each file and validating the checksum - which is part of the answer. It basically protects the files on a brick from silent data corruption - it does not ensure that each replica is consistent with each other. I believe that replica compare and automatic healing, are features being worked on for a future release - not sure of timing, but maybe one of the devs can chime in.

RHGS 3.1.2 is the current version. -- Kaleb _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx <mailto:Gluster-users@xxxxxxxxxxx> http://www.gluster.org/mailman/listinfo/gluster-users _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-users
