These are my recommendations for controlling access to the LINSTOR controller:

To backup the LINSTOR controller’s DB, currently, you’d have to do something like this:

  • drbdreactor-ctl disable --now <controller service> on all nodes
  • mount /dev/drbdX /somewhere
  • copy the database out of the mount point to somewhere as your backup
  • umount /dev/drbdX
  • drbdreactor-ctl enable --now <controller service> on all nodes
