how to validate this? any particular command to execute? description?
when tiering rebalancer runs you will find this file /var/lib/glusterd/vols/test/tier/<uuid>.pid thatz the validation of this bug. It will not the pid file of dht rebalancer.
Noting this snippet from parent bug for QE reference and understanding: ============ tiering/rebalance: Use separate pid/socket file for tiering When promotion/demotion daemon starts, it uses the same pidfile as rebalance. This patch will introduce a different pid file for the same. =============
I have verified the bug in following scenarios: 1)attach-tier ---> tier deamon kicks off 2)detach-tier start------->tier deamon stops 3)rebalance volumename tier start------->tier deamon kicks off 4)stop tier volume--->tier deamon dies 5)New volume has new tier deamon kicked of per node per volume seperately The Process socket was available at /var/lib/glusterd/vols/<volname>/tier/<pidname>.pid hence moving the bug to verified Logs and sosreports are attached Note: But for a detach-tier start, a seperate PID under rebalance folder is getting created to move files to cold tier
