[Gluster-users] never ending logging

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/
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.

Regards
Nikhil Ladha
