[email protected] − System unit to (de)activate backing LVM2 LVs for a specific DRBD resource
drbd−lvchange@RESNAME.service
If you try to start (configure) a DRBD using the drbd@RESNAME.service, chances are that this fails because at the time its backing block devices are not (yet) available.
If you know those backing devices are LVM2 LVs, enable this optional service, to add an explicit dependency on those LVs and try to activate them first. It will also de−activate them on stop.
systemctl enable drbd−[email protected]
