Hello,

just to put my mind at ease, I suppose using the 8.0.7 userland tools from
Debian backports on my Etch machines with a custom kernel and a 8.0.11
drbd module is not going to send my data to the big bitbucket in the sky,
right? I mean, API and protocol are the same, so.... 

Also I'm pondering about enabling use-bmbv, the machines and all disks are
indeed identical. Though I what scares me a bit is the 
"the physical disks of the software raid are of exactly the same type"
statement. If a drive fails in a RAID 5, obviously the physical
characteristics are no longer the same, but isn't the MD driver masking
all that from DRBD anyway? Also if a drive gets replaced at some stage by
a newer/different model with the same or larger capacity while keeping the
actual MD partition(s) exactly the same size as on the other RAID members,
shouldn't that be fine and transparent?

Regards,

Christian
