Hi all,
I use glusterfs 4.1.3 non-root user geo-replication in a cascading setup. The gsyncd.log on the master is fine, but I have some strange changelog warnings and errors on the interimmaster:

I had those issues in the past with 4.1.2 as well. I could fix it only by deleting the geo-replication and the gluster volume and re-create everything.
If I delete the geo-replication and delete the changelogs directory or the CHANGELOG files, I get this error:
gsyncd.log

I read somewhere that if I delete the geo-replication with “reset-sync-time”, the changelogs are cleared, but this doesn’t happen.
How can I reset the changelog without deleting all data?
