Hello Team,
We are running a setup of 3-way replica HC gluster setup configured during
the initial deployment from the cockpit console using ansible.
NODE1
- /dev/sda (OS)
- /dev/sdb ( Gluster Bricks )
* /gluster_bricks/engine/engine/
* /gluster_bricks/data/data/
* /gluster_bricks/vmstore/vmstore/
NODE2 and NODE3 with a similar setup.
Hosted engine was running on node2.
- While moving NODE1 to maintenance mode along with stopping the
gluster service as it prompts before, Hosted engine instantly went down.
- I start the gluster service back on node1 and start the hosted engine
again and found hosted engine started properly but getting crashed again
and again within frames of second after a successful start because HE
itself stopping glusterd on node1. (not sure) but cross-verified by
checking glusterd status.
*Is it possible to clear pending tasks or not let the HE to stop
glusterd on node1?*
*Or we can start the HE using other gluster node?*

The Hosted Engine storage domain should have the backup-volfile-servers
mount options specified, so that even if the node used to mount the gluster
volume initially goes down, it can try with an alternate server.
Can you check if this is set? ( check
/etc/ovirt-hosted-engine/hosted-engine.conf
or hosted-engine --get-shared-config mnt_options --type=he_shared)
If not set, you can update the mount options for HE domain using
hosted-engine --set-shared-config
mnt_options="backup-volfile-servers=<server2>:<server3>"
--type=he_shared
