Result:
During Geo-replication session, if the master node experiences a connectivity issue, the changes identified by the file system crawl process is not retained when the process is terminated. When the master nodes is back online, the file system crawl restarts and identifies the changes again. As a result, there is a performance degradation.

Kotresh HR 2014-01-02 10:30:43 UTC Doc Text During Geo-replication session, if the master node experiences a connectivity issue, the changes identified by the file system crawl process is not retained when the process is terminated. When the master nodes is back online, the file system crawl restarts and identifies the changes again. As a result, there is a performance degradation. Cause: The xtime updation was maintained only at root
directory. It was not maintained per directory.

Consequence: While doing first xsync crawl, disconnection
with slave causes the geo-rep to re-crawl the whole
file system and generate XSYNC-CHANGELOGS again.

Fix:
The fix is given to maintain the xtime per directory
and is updated with slave's stime after the successful
sync of all the files and subdirectories under it. This
provides the infrastructure for the xsync to skip the
directories which are already synced when it restarts.

Result:
xsync does not generate XSYNC-CHANGELOGS for already
synced directory when it re-crawls the file system due
to disconnection of the geo-rep session with the
slave.

Previously, when the first xsync crawl was in progress, disconnection with the slave volume caused Geo-replication to re-crawl the entire file system and generate XSYNC-CHANGELOGS. With this update, xsync skips the directories which are already synced to the slave volume.
