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

Hi Everyone,
As I was getting "OSError: [Errno 107] Transport endpoint is not connected: '.gfid/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8' " error in the primary master node gsyncd log, So I started searching this file details and I found this file in the brick, under the .glusterfs folder on master1 node.
Path on master1 - /opt/tier1data2019/brick/.glusterfs/d5/3f/d53fad8f-84e9-4b24-9eb0-ccbcbdc4baa8
[root at master1 ~]# ls -lrt /opt/tier1data2019/brick/.glusterfs/d5/3f/
-rw-r--r-- 2 root root 15996 Dec 14 10:10 d53feba6-dc8b-4645-a86c-befabd0e5069

-rw-r--r-- 2 root root 801740 Feb 8 11:40 d53f71f8-e88b-4ece-b66e-228c2b08d6c8
Now I have noticed two things:
First, this file is only present on the primary master node (master1) and doesn't exist on master2 and master3 nodes.
Second, this file has different file attributes than other files in the folder. If you check the second column of the above output, every file has "2", but this file has "1".
Now, can someone please guide me why this file has "1" and what I should do next? Is it safe to copy this file to the remaining two master nodes, or should I delete it from master1?
Many thanks,
Anant

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 ?
