[Gluster-users] never ending logging

Thanks for feedback.

No problem at all before node rejection, all worked fine but I had to renew SSL
certificates which were about to expire. The node rejection occured after
certificate renewal.

I'll send you links for sosreports (Debian) in separate mail.

Regards,
Nicolas.

Hi,
It seems to be like using the step mentioned here [
https://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Administrator%20Guide/Resolving%20Peer%20Rejected/
|
https://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Administrator%20Guide/Resolving%20Peer%20Rejected/
] is the reason you are facing so much problems. You said that the vol files in
all the nodes are different which should never happen, because that's the
purpose of shd to heal the vol files in case of any differences in the files,
but dues to several deletions of the files and starting the glusterd service
again and then disconnection of the nodes has lead to a state where that task is
left incomplete. And whenever you are again trying to start the volume or get
the status then that heal runs but it's not able to complete as it's not
able to get a proper head through which it could make the heal.
Before the node rejection part, and you applying those steps to rectify it, did
everything worked fine?
Also, can you share the sos-reports if not then the vol files which you see as
different. So, that I can be sure of that.

Hi,
It says syntax error in the log you shared, so there must be some mistake in
what you are passing as an argument or some spelling mistake. Otherwise, how
come it will run on one them and not on other having same configuration?
Also, can you please share the complete log file.
And try restarting all the nodes in the tsp, and execute the commands.

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/ |
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.

Nikhil Ladha

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/
|
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/ |
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 ?

Regards,
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

Objet: Re: [Gluster-users] never ending logging

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
