[Gluster-users] never ending logging

Tue Apr 28 07:31:45 UTC 2020

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.

Regards
Nikhil Ladha
