[Gluster-users] geo-rep: remote operation failed - No such file or directory

Mon Feb 22 07:57:14 UTC 2016

Hi Milind,

Any news on this issue? I was wondering how can I fix and restart my geo-replication? Can I simply delete the problematic file(s) on my slave and restart geo-rep?

Regards
ML

Hi Milind,

Thank you for your short analysis. Indeed that's exactly what happens, as soon as I restart geo-rep it replays the same over and over as it does not succeed. 

Now regarding the sequence of the file management operations I am not totally sure how it works but I can tell you that we are using ownCloud v8.2.2 (www.owncloud.org) and as storage for this cloud software we use GlusterFS. So it is very probable that ownCloud works like that: when a user uploads a new file if first creates it with another temporary name which it then either renames or moves after successful upload. 

I have the feeling this issue is related to my initial issue which I have reported earlier this month: 
https://www.gluster.org/pipermail/gluster-users/2016-February/025176.html

For now my question would be how do I get to restart geo-replication succesfully?

Regards
ML

As per the slave logs, there is an attempt to RENAME files
i.e. a .part file getting renamed to a name without the
.part suffix

Just restarting geo-rep isn't going to help much if
you've already hit the problem. Since the last CHANGELOG
is replayed by geo-rep on a restart, you'll most probably
encounter the same log messages in the logs.

Are the .part files CREATEd, RENAMEd and DELETEd with the
same name often? Are the operations somewhat in the following
sequence that happen on the geo-replication master cluster?

CREATE f1.part
RENAME f1.part f1
DELETE f1
CREATE f1.part
RENAME f1.part f1
...
...

If not, then it would help if you could send the sequence
of file management operations.
