I am preparing for my first deployment of DRBD and have a few
questions.
My initial setup is two servers. One is a functioning server and
will
be the primary and the second is currently not used and will be my
secondary.
The DRBD instructions say:
"After you have installed DRBD, you must set aside a roughly
identically sized storage area on both cluster nodes. This will
become
the lower-level device for your DRBD resource."
What is this storage area for?
This is where the data you want replicated will go. So if you have
/dev/sdb as the block device you want to replicate, you will need a
block device of the same size on your secondary to replicate to.
How big does it need to be?
However big you want it :)
Is this just where DRBD keeps it's own data to function or is this
where the actual replicated source data needs to be and where the
destination will go?
Thanks!
Cameron

Thanks Brian!
So I don't need to do anything on the primary and I can use the
existing device where the data lives now as the lower-level location?
I know about the internal meta data at the end and allowing for it.
So for my secondary can I do the same with that? It has an existing OS
and different files in /etc than the primary and I want to make it
identical to the primary so in case of the primary failing the
secondary would become a live system identical to the primary.
How do I achieve this?
How do I remove the files from the secondary and populate the
secondary with matching data from the primary?
Also is /dev/mapper/VolGroup01-LogVol00 the appropriate
