[Gluster-users] Self healing metadata info

Hi,

If a brick is down and comes back up later, how does Glusterfs know which
files in this brick need to be 'self-healed'?

Since the metadata of whether to 'heal' is stored as an xattr in a replica
on *other* bricks. Does Glusterfs scan these files on the other bricks to
see if one is "accusing" its replica and therefore need to "heal" its
replica?

In short, does Glusterfs keep a record of "writes" to a brick when a brick
is down and apply these "writes" to the brick when its backup?


Thanks,
JPro
