Hi,

Those issues are fixed in gluster v6.6. Please try 6.6. Non-root geo-rep is stable in v6.6.

Hi
We are using Gluster 5.6 now.
We tested 6.2 earlier but it had the gluster-mountbroker issue.(https://bugzilla.redhat.com/show_bug.cgi?id=1709248).

Hi Deepu,

Hi Users/Development Team
We have set up a Geo-replication session with non-root in slave setup in our DC.
It was working well with Active Status and Changelogcrawl.

We were mounting the master node and the file is being written in it.
We were running some process as the root user so the process wrote some file and folder with root permission.
After stopping the geo-replication and starting the process the session went to the faulty state.
How to recover?
