If I was on your shoes, I would backup drbd resource files usually stored within /var/lib/linstor.d on each satellite node. Those are resource config files which linstor is managing centrally from the controller to orchestrate the cluster. The chances are that you will loose all those files once the satellites are brought back online, so it would be a good idea to keep them as a point of reference when rebuilding the controller. That being said, it might be a good idea to consult professional support from Linbit if this is a production environment.</span></p>

backup systems) but both are offline for at least the next week.<br>

So, is there any other method to "re-create" or otherwise setup a <br>

I know, would be a good idea to setup some HA and/or some regular DB <br>
backup and replication to other nodes, but in the meantime, what are the <br>
options to get linstor-controller or at least linstor-satellites all up <br>
and running?<br>
