Hello gents,
Please understand that DRBD is block based replication.
It replicates devices (disks, LVM logical volumes etc.)
It cannot replicate a single directory (e.g. /usr/local/pf ).
You would have to mount /usr/local/pf in it's own volume.
While doable, it's probably just overkill for most people.
Regards,
