I am currently testing HA linstor controller vm as explained in:
As recommennded, I enabled the drbd service (and set the --keep-res flag
in linstor-satellite startup) in in order to have the controller vm
storage resource brought up at boot.
I noted that after boot more or less half of links in /dev/drbd/by-res
are missing, and this has the unpleasant effect to block startup of
This issue started appearing after having enabled drbd systemd unit, and
does not happens if I keep only one of the two services enabled.
I guess that there is some race condition between drbd and
linstor-satellite startup (with the latter deleting .res files while
drbd bis basing on them to bring resorces up). So I tried to setup a
dependency on drbd using "systemctl edit linstore-satellite" (similarly
to the "Service" stance which I already set)
This seems to resolve, may be there are more elegant ways to cope with that.
