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
