One more thing,<br>
<br>
Need not worry too much about the SKIPPED_GFIDs list. Due to entry
failure Geo-rep is unable to create the entry and successive rsync
fails for that file, but all the GFIDs which were in the same batch
is logged as failures. Which is not true, Rsync does partial sync
skips the failed GFIDs and syncs rest of the files. I am working on
fixing the logging issue.<br>

Looks like GFID conflict in Slave. (Same filename with different
GFID exists in Slave undeleted may be due to unlink failure or any
other failure)
<br>
Need to identify the cause for GFID conflict. Please share the
workload details or share the changelogs from brick

"ENTRY FAILED" shows file exists error but shows different GFID

So something funky was happening for an hour 4 days ago. Given
the volume
<br>
is on EBS, maybe there was some glitch there.

<br>
I can also find the corresponding failures on the master:

What is the right way to retry failed items?
<br>
Can I get a list of them somehow so that I could touch them in
hopes to fix
<br>
this?
<br>
I wonder why does it not retry the items automatically?

Chris here[1] mentioned about a bug in rsync (thanks!). Could
that be
<br>
the issue here?
<br>
<br>
Mind checking rsync version used?

again
<br>
<blockquote type="cite">at some point.
<br>
<br>
Can someone provide me with information on how to check
which files are
<br>
causing failures, and what are the actual failures? Or point
me to the
<br>
relevant part in the docs?
