[DRBD-user] Stacked resource not syncing

[Tony den Haan]

Hi,


I've tried setting up three-way replication following
https://docs.linbit.com/docs/users-guide-8.4/#s-three-nodes
This seems to work, no errors, but when i try taking lvm snapshot of the
resource on the backup node i see data is not synced until i actually
force a sync using drbdadm invalidate or verify
Am i wrong in assuming this approach should work?
Could it be because the initial 2 nodes are managed by pacemaker and the
backup node isn't?


BTW i think the users guide should mention "drbdadm --stacked  --
--overwrite-data-of-peer primary drbdX-U" to get it going
