Re: never ending logging

Hi.

Not really worked well, I restarted node 2 at least a dozen of times until almost all bricks go online but the Rejected state disapeared after applying the fix.
I'm not able to create a volume as all gluster commands are issuing the "Another transaction is in progress" error.
All ping are less than 0.5ms.

I noticed another error in brick logs for a failed brick :

Hi,
Okay. So, after applying the fix everything worked well? Means all the peers were in connected state?
If so, can you try creating a new volume without enabling SSL and share the log, and also for the volume that is not starting can you try the steps mentioned here https://docs.gluster.org/en/latest/Troubleshooting/troubleshooting-glusterd/ only in the 'Common issues how to resolve them section" and what logs do you get?
Also, could you ping test all the peers?
And the error 'failed to fetch volume files' occurs as it is not able to fetch the vol file from it's peers, as all the peers in the cluster share the same vol file for a volume.

Hi.

No operation on any volume nor brick, the only change was SSL certificate renewal on 3 nodes and all clients. Then, node 2 was rejected and I applied following steps to fix : https://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Administrator%20Guide/Resolving%20Peer%20Rejected/
I also saw https://docs.gluster.org/en/latest/Troubleshooting/troubleshooting-glusterd/ but solution wasn't compatible as cluster.max-op-version doesn't exist and all op-version are the same on all 3 nodes. 

The strange thing is error  "failed to fetch volume file" occurs on the node owning the brick, does it means it can't access it's own brick ?

Nicolas.

Hi,
Since, all things are working fine except few bricks which are not coming up, I doubt there is any issue with gluster itself. Did you by chance made any changes to those bricks or the volume or the node to which they are linked?
And as far as SSL logs are concerned, I am looking into that matter.

Thanks for reply.

I updated storage pool in 7.5 and restarted all 3 nodes sequentially.
All nodes now appear in Connected state from every node and gluster volume list show all 74 volumes.
SSL log lines are still flooding glusterd log file on all nodes but don't appear on grick log files. As there's no information about volume nor client on these lines I'm not able to check if a certain volume produce this error or not.
I alos tried pstack after installing Debian package glusterfs-dbg but still getting "No symbols" error

I found that 5 brick processes didn't start on node 2 and 1 on node 3

Hi,
As you mentioned that the node 2 is in "semi-connected" state, I think due to that the locking of volume is failing, and since it is failing in one of the volumes the transaction is not complete and you are seeing a transaction error on another volume.
Moreover, for the repeated logging of lines :
SSL support on the I/O path is enabled, SSL support for glusterd is enabled and using certificate depth 1
If you can try creating a volume without having ssl enabled and then check if the same log messages appear.
Also, if you update to 7.5, and find any change in log message with SSL ENABLED, then please do share that.

Regards
Nikhil Ladha
