My main motivation is the desire for a compressed filesystem. I have experimented with using VDO for that purpose and it works, but the setup is complex and I donโt know if I trust it to work well when VDO is in a stack of Pacemaker cluster resources. If there a better way of getting compression to work above DRBD?

The lowest layer RAIDZ will serve as the DRBD backing device. Then I would build another ZFS filesystem on top to benefit from compression.
