[ale] DRBD - anyone using this?

[Chuck Payne]

We are using where I work for 4 clusters each made of two nodes.  As Jim
stated it not a back up, it so that your data is synced at the same time.
We have the systems flip and are very happy because the data was in sync.
We are working with Linbit the people that wrote drbd because unless you
know someone that a master a pacemaker, corosync, and ipmi. Then you will
have issues. Our issues the size of DB, we are work with them to get
STONITH setup.

DRBD great for DB and Website. I don't recommend NFS. I did testing and
there are issues.
