[Gluster-users] Reliable Geo-Replication

[Shwetha Acharya]

Hi Felix,

Have you deleted the session with reset-sync-time and recreated the session?

If yes, the crawling starts from beginning.
Which happens in this way:

It begins with hybrid crawl, as data is already in  master before re
creating the geo-rep session. If geo-rep session is craeted before creating
data on master, hybrid crawl does not occur. *Note*:  renames and deletes
will not be synced in hybrid crawl.

Then it gradually changes to history crawl and changelog crawl.

You can wait for sync to complete by setting a checkpoint, need not try #
setfattr -n glusterfs.geo-rep.trigger-sync -v "1" <file-path>
reset-sync-time will take considerable time to finish syncing, as I stated
earlier, it is time consuming one.

Modes does not affect # setfattr -n glusterfs.geo-rep.trigger-sync -v "1"
<file-path>

Regards,
Shwetha
