Are you sure that the DRBD is working properly ?

I thought I had it working, but I keep running into problems. Sometimes when I demote a DRBD resource on Node A and promote it on Node B, and I try to mount the filesystem, the system complains that it cannot read the superblock. But when I move the DRBD primary back to Node A, the file system is mountable again. Also, I have problems with filesystems not mounting because the vdo devices are not present. All kinds of issues.

There is no VDO RA according to my knowledge, but you can use systemd service as a resource. Yet, the VDO service that comes with thr OS is a generic one and controlls all VDOs - so you need to create your own vdo service. Best Regards, Strahil Nikolov

But the cluster won’t fail over. Is there a VDO cluster RA out there somewhere already?

For DRBD there is enough info, so let's focus on VDO. There is a systemd service that starts all VDOs on the system. You can create the VDO once drbs is open for writes and then you can create your own systemd '.service' file which can be used as a cluster resource.
