JohnnyElvis commented 2 years ago

It wouold be awesome to have DRBD covered in cockpit-storaged.

Priority in descending order:

!. (would be awesome) Show replication status of "cat /proc/drbd" via UI. Detailed status message information can be found here - https://support.sciencelogic.com/s/article/1176

sample output

############

  1. (would be nice) Switch between primary/secondary node - via Pacemaker/Heartbeat - we can discuss this

  2. Set up block device replication - we can discuss this as well

    Steps 3-6 from this documentation - https://www.tecmint.com/setup-drbd-storage-replication-on-centos-7/

Duplicate of https://github.com/cockpit-project/cockpit/issues/13362 From ^:

This is definitively something that we won't do in the cockpit project itself -- it should be developed as a separate project, by someone with the necessary domain knowledge. Thus closing this for the cockpit project. Thanks!
