--- Comment #2 from Aravinda VK <avishwan at redhat.com> ---
Root caused the issue:

If files created before Geo-rep create, xtime xattr will not be available.
After geo-rep create it enables indexing. Marker will update xtime for all the
files which are created/modified after indexing is enabled.

Geo-rep uses changelog register time as upper limit for xsync to decide a file
should be synced or not. It compares xtime of each file >= upper_limit, If
xtime is not found it updates xtime with current time. But this updated xtime
is greater than upper_limit, xsync skips this file by thinking that changelog
will pick this. But changelog will not have CREATE info for this file only
SETXATTR/DATA is recorded.
