[DRBD-user] DRBD + ZFS

[Eric Robinson]

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 don’t 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?

Not sure ZFS is the right choice as an underline for a resource,
it is powerful but also complex (as a code base), which will probably will make it slow.

unless you are going to expose the ZVOL or the dataset directly to be consumed,
stacking ZFS over DRBD over ZFS, seems to me as a bad idea.

I’m considering deploying DRBD between ZFS layers. The lowest layer RAIDZ will serve as the DRBD backing device. Then I would build another ZFS filesystem on top to benefit from compression. Any thoughs, experiences, opinions, positive or negative?
