Hi 
@Aravinda,

Thanks for opening the gitlab issue.

I tried to remove the secret.pem.pub from master1 and create it again. Then, I ran georep
 create push pem, which copied the missing entry to the drtier1data (slave) node. However, I am still getting the same error. I have also checked the logs on drtier1data (slave) node and found the following logs.

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 
@Aravinda,

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.
After that, I ran the following commands.

gluster system:: execute gsec_create
gluster volume geo-replication tier1data drtier1data::drtier1data

In one of the thread, I saw the SSH public key is manually copied to secondary node's authorized_keys
 file. Check if that entry starts with "command=" or not. If not added, delete the entry in that file (or delete all Georep related entries in that file) and run Georep create push-pem force again.

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.

Hi Anant,

You need to run the gsec_create command when a new node is added to Primary or secondary

gluster system:: execute gsec_create
gluster volume geo-replication tier1data drtier1data::drtier1data create push-pem force
gluster volume geo-replication tier1data drtier1data::drtier1data start
gluster volume geo-replication tier1data drtier1data::drtier1data status

Or use the Geo-rep setup tool fix the key related issues and resetup (https://github.com/aravindavk/gluster-georep-tools)

gluster-georep-setup tier1data drtier1data::drtier1data

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.

gluster volume geo-replication tier1data drtier1data::drtier1data
 delete
gluster volume geo-replication tier1data drtier1data::drtier1data
 create push-pem force
gluster volume geo-replication tier1data drtier1data::drtier1data
 start
gluster volume geo-replication tier1data drtier1data::drtier1data
 status

I have tried to check the drtier1data logs as
 well, and all I can see is master1 connects to drtier1data and send disconnect after 5 seconds, please check the following logs from 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.

Many thanks,

Anant

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

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.

Strahil Nikolov

Hi 
@Strahil Nikolov,

I have checked the ssh connection from all the master servers and I can ssh
drtier1data from master1 and master2 server(old
 master servers), but I am unable to ssh drtier1data from
 master3 (new node).

[root@master3 ~]# ssh -i /var/lib/glusterd/geo-replication/secret.pem root@drtier1data
Traceback (most recent call last):
  File "/usr/libexec/glusterfs/python/syncdaemon/gsyncd.py", line 325, in <module>
    main()
  File "/usr/libexec/glusterfs/python/syncdaemon/gsyncd.py", line 259, in main
    if args.subcmd in ("worker"):
TypeError: 'in <string>' requires string as left operand, not NoneType
Connection to drtier1data closed.

But I am able to ssh
 drtier1data from
 master3 without using the
georep key.

[root@master3 ~]# ssh  root@drtier1data
Last login: Sun Jan 28 01:16:25 2024 from 87.246.74.32

Also, today I restarted the gluster server on master1 as geo-replication is trying to be active from master1 server, and sometimes I
 am getting the following error in gsyncd.log

Don't forget to test with the georep key. I think it was /var/lib/glusterd/geo-replication/secret.pem

Hi Anant,

i would first start checking if you can do ssh from all masters to the slave node.If you haven't setup a dedicated user for the session, then gluster is using root.

Hi All,

I have run the following commands on master3, and that has added master3 to geo-replication.

gluster system:: execute gsec_create

gluster volume geo-replication tier1data drtier1data::drtier1data create push-pem force

gluster volume geo-replication tier1data drtier1data::drtier1data stop

gluster volume geo-replication tier1data drtier1data::drtier1data start

Now I am able to start the geo-replication, but I am getting the same error.

Hi There,

We have a Gluster setup with three master nodes in replicated mode and one slave node with geo-replication.

# gluster volume info

Volume Name: tier1data

Type: Replicate

Volume ID: 93c45c14-f700-4d50-962b-7653be471e27

Status: Started

Snapshot Count: 0

Number of Bricks: 1 x 3 = 3

Transport-type: tcp

Bricks:

Brick1: master1:/opt/tier1data2019/brick

Brick2: master2:/opt/tier1data2019/brick

Brick3: master3:/opt/tier1data2019/brick

master1 |master2 |  ------------------------------geo-replication----------------------------- | drtier1datamaster3 |

We added the master3 node a few months back, the initial setup consisted of 2 master nodes and one geo-replicated slave(drtier1data).

Our geo-replication was functioning well with the initial two master nodes (master1 and master2), where master1 was active and master2 was in passive mode. However, today, we started experiencing issues where geo-replication suddenly stopped and became stuck
 in a loop of Initializing..., Active.. Faulty on master1, while master2 remained in passive mode.

Upon checking the gsyncd.log on the master1 node, we observed the following error (please refer to the attached logs for more details):

E [syncdutils(worker /opt/tier1data2019/brick):346:log_raise_exception] <top>: Gluster Mount process exited [{error=ENOTCONN}]

# gluster volume geo-replication tier1data status

MASTER NODE            MASTER VOL    MASTER BRICK                SLAVE USER    SLAVE                                            SLAVE NODE    STATUS             CRAWL STATUS    LAST_SYNCED

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

master1    tier1data     /opt/tier1data2019/brick    root          ssh://drtier1data::drtier1data    N/A           Faulty           N/A             N/A

master2    tier1data     /opt/tier1data2019/brick    root          ssh://drtier1data::drtier1data                  Passive            N/A             N/A

Suspecting an issue on the drtier1data(slave), I attempted to restart Gluster on the slave node, also tried to restart drtier1data server without any luck.

After that I tried the following command to get the Primary-log-file for geo-replication on master1, and got the following error.

# gluster volume geo-replication tier1data drtier1data::drtier1data config log-file

Staging failed on master3. Error: Geo-replication session between tier1data and drtier1data::drtier1data does not exist.

geo-replication command failed

Master3 was the new node added a few months back, but geo-replication was working until today, and we never added this node under geo-replication.

After that, I forcefully stopped the geo-replication, thinking that restarting geo-replication might fix the issue. However, now the geo-replication is not starting and is giving the same error.

# gluster volume geo-replication tier1data drtier1data::drtier1data start force

Staging failed on master3. Error: Geo-replication session between tier1data and drtier1data::drtier1data does not exist.

geo-replication command failed

Can anyone please suggest what I should do next to resolve this issue? As there is 5TB of data in this volume, I don't want to resync the entire data to drtier1data. Instead, I want to resume the sync from where it last stopped.

Thanks in advance for any guidance/help.

Kind regards,

Anant
