The primary volume (tier1data) is mounted by all other clients, and I can see that 24 clients are connected using the following command:
Are you asking if I can mount the primary volume on the primary master node itself? From: Aravinda <aravinda@xxxxxxxxxxx>

Geo-rep delete and create will recreate the session and continue syncing from where it
stopped last time. Last sync time is remembered in the xattrs of Brick root of Primary volume (`trusted.glusterfs.<primary-volume-id>.<secondary-volume-id>.stime`).
If reset-sync-time option used with delete, then it will remove the above mentioned xattr.
When Geo-rep session is created again, it will start a new session.
New session starts with Hybrid crawl then switches to History crawl and then switches to
Changelog crawl. History crawl does file system crawl and all the files will be identified as to be synced. Geo-rep uses rsync to sync the files (Change detection is done externally and rsync only gets the list of files to be synced), rsync will only sync
the difference if any.
Only issue I see of using this option is it may take lot of time to reach the current
time and start syncing the recent files.

Please share the errors you see from Primary geo-rep logs.

Hi All,
Does anyone know what will happen if I delete
the geo-replication with reset-sync-time and create it again, Will it copy the whole data again, or will it just check the files and then copy the new remaining files?

Hello Everyone,
I'm running out of options, I've already tried rebooting the physical servers without any luck.
Now, I am thinking, should I try to delete the geo-replication with reset-sync-time? Will that resolve the issue? We have 6TB of data, so will running delete with reset-sync-time copy the whole 6TB of data again, or will it just check the files and then copy the new remaining files?
I have checked the documentation, and it's not clear what will happen with the files already present on the slave volume. Will they be recopied, or just checked and skipped in case of deleting the session and creating it again? Anyone have any experience around this situation?
Any help is appreciated.
Many thanks,

Hi Anant,

Still same thing happening, One thing I have noticed that everytime master1 is trying to be primary node,
how it's selected that which node will be primary node in the geo-replication?
Gsyncd worker from the first node of the Replica bricks will become Active and participate
in syncing. If the Active worker node goes down then the other worker becomes Active (Not when it is Faulty). Geo-rep can use Gluster meta volume to hold a lock and automatically switch when a Active worker is Faulty (Refer: Meta Volume config
https://docs.gluster.org/en/main/Administrator-Guide/Geo-Replication/#configurable-options).
I think we can enhance Geo-rep to accept configuration option to select a worker as Active
manually. I will think about it and update here if possible.

Second, I have noticed
in
the ".ssh/authorized_keys" file on the secondry node, master2 and master3
have 2 entries (command="/usr/libexec/glusterfs/gsyncd" AND command="tar ${SSH_ORIGINAL_COMMAND#* }", but
master1 node have only one entry with command="tar ${SSH_ORIGINAL_COMMAND#* }" , This indicates that there is a missing entry for master1 with the command="/usr/libexec/glusterfs/gsyncd",
Does it make any sense?
Missing entry is the problem as you observed. Delete /var/lib/glusterd/geo-replication/secret.pem.pub
file in master1 and then run gsec_create, georep create push pem again.

Hi

As advised, I have removed all the master server-related entries from the ".ssh/authorized_keys" file on the secondary node. Then, I ran the "ssh-copy-id root@drtier1data" command on all the masters for passwordless SSH and verified that I can access the drtier1data server from all the master nodes.

Hi
@Aravinda,
I used the exact same commands when I added master3 to the primary geo-replication. However, the issue is that the master3 node is in a passive state, and master1 is stuck in a loop of Initializing -> Active -> Faulty. It never considers master2 or master3 as the primary master for geo-replication.
If master1 can connect to the secondary (drtier1data) server, and I see the following message in the master1 logs which says "SSH connection between master and slave established.", do you still think it could be related to key issues? I am willing to rerun the commands from master1 if you advise. 2024-01-30 23:33:14.274611] I [resource(worker

Hi All,
As per the documentation, if we use `delete` only
it will start the replication from the time where it was left before deleting the session, So I tried that without any luck.

delete
gluster volume geo-replication tier1data drtier1data::drtier1data

Hello Everyone,
I am looking for some help. Can anyone please suggest if it's possible to promote a master node to be the primary in the geo-replication session?
We have three master nodes and one secondary node. We are facing issues where geo-replication is consistently failing from the primary master node. We want to check if it works fine from another master node.
Any guidance or assistance would be highly appreciated.

Hi
@Strahil Nikolov,
We have been running this geo-replication for
more than 5 years and it was working fine till last week, So I think it shouldn't be something which was missed in the initial setup, but I am unable to understand why it's not working now.
I have enabled SSH Debug on the secondary node(drtier1data),
and I can see this in the logs.

As per the above logs, drtier1data node is getting
SIGCHLD from
master1. (Received disconnect from XX.236.28.58 port 53082:11:
disconnected by user)
Also, I have checked the gsyncd.log on master1,
which says "SSH: SSH connection between master and slave established. [{duration=1.7277}]", which means passwordless ssh is working fine.
As per my understanding, Master1 can connect to
the drtier1data server, and then the geo-replication status changes to Active --> History Crawl and then something happens on the master1 which triggers the SSH disconnect.
is it possible to change the master node in geo-replication
so that we can mark master2 as primary, instead of master1?
I am really struggling to fix this issue, Please
help, any pointer is appreciated !!!
Many thanks,
Anant

Strahil,
As mentioned in my last email, I have copied the
gluster public key from master3 to secondary server, and I can now ssh from all master nodes to secondary server,
but still getting the same error.
[root@master1 geo-replication]# ssh root@drtier1data
-i /var/lib/glusterd/geo-replication/secret.pem

Gluster doesn't use the ssh key in /root/.ssh,
thus you need to exchange the public key that corresponds to /var/lib/glusterd/geo-replication/secret.pem . If you don't know the pub key, google how to obtain it from the private key.
Ensure that all hosts can ssh to the secondary
before proceeding with the troubleshooting.
