|Fixed In Version:||glusterfs-3.8.4-1||Doc Type:||Bug Fix|
If geo-replication status was requested after an upgrade but before glusterd was started again, an empty monitor.status was created and the session status was listed as 'Started'. This meant that when glusterd restarted, because monitor.status was empty, a fresh geo-replication session started instead of the previous session being resumed. This has been corrected so that an empty monitor.status results in an error, and geo-replication status is listed as 'Stopped' after an upgrade but before glusterd restarts.

Description Rahul Hinduja 2016-06-17 09:31:29 UTC
Description of problem: ======================= Found the situation, where stopped the existing geo-replication session and upgraded each master node one by one. Upgraded nodes needed reboot since, they upgraded the kernel version. Had 3 master nodes: <n1,n2 and n3> all with 3.1.2 bits and geo-replication in stopped state. 1. Upgrade n1 to 3.1.3 and do not reboot 2. Check geo-rep session, it is in stopped state. 3. Upgrade n2 to 3.1.3 and reboot 4. Check geo-rep session, it is in stoppped state. 5. Upgrade n3 to 3.1.3 and reboot 6. Check geo-rep session, it is in stopped state. 7. reboot n1 7. Check geo-rep session, it is in started state. Expected is to be in stopped state. Version-Release number of selected component (if applicable): ============================================================= glusterfs-3.7.9-10 How reproducible: ================= 2/2 Additional info: ================ I have tested reboot scenarios as part of 3.1.3 and as mentioned above, the stopped state remains in stop state until all gets rebooted once. I will try to narrow down the use case without upgrade.

Upgraded from 3.1.2 to 3.2.0 (glusterfs-geo-replication-3.8.4-18.el7rhgs.x86_64). Geo-rep sessions remains in stopped state after rebooting all nodes in cluster. Moving this bug to verified state.
