[Gluster-users] __Geo-replication status is getting Faulty after few seconds

Hi @Aravinda<mailto:aravinda at kadalu.tech>,


I have checked the rsync version, and it's the same on primary and secondary
nodes. We have rsync version 3.1.3, protocol version 31, on all servers.
It's very strange that we have not made any changes, that we are aware of,
and this geo-replication was working fine for the last 5 years, and suddenly it
has stopped, and we are unable to understand the root cause of it.


I have checked the tcpdump and I can see that the master node is sending RST to
the secondary node when geo-replication connects, but we are not seeing any RST
when we do the ssh using the root user from master to secondary node ourselves,
which makes me think that geo-replication is able to connect to the secondary
node but after that, it's not liking something and tries to reset the
connection, and this is repeating in a loop.


I have also enabled geo-replication debug logs and I am getting this error in
the master node gsyncd logs.

It will keep track of last sync time if you change to non-root user. But I
don't think the issue is related to root vs non-root user.

Even in non-root user based Geo-rep, Primary volume is mounted using root user
only. Only in the secondary node, it will use Glusterd mountbroker to allow
mounting the Secondary volume as non-priviliaged user.

Check the rsync version in Primary and secondary nodes. Please fix the versions
if not matching.

No, It was setup and running using the root user only.

Do you think I should setup using  a dedicated non-root user? will it keep the
track of old files or will it consider it as a new geo-replication and copy all
the files from the scratch?

Have you tried setting up gluster georep with a dedicated non-root user ?
