And I though DRDB is not a filesystem at all, but a block sharing 
protocol.

http://www.drbd.org/home/mirroring/

is very clear about it:

"A consequence of mirroring data on block device level is that you can 
only access your data (using a file system) on the active node. This is 
not a shortcoming of DRBD; this is caused due to the nature of most file 
systems (ext3, XFS, JFS, ext4, ...). These file systems are designed for 
one computer accessing one disk, so they cannot cope with two computers 
accessing one (virtually) shared disk."

Just use a filesystem that allows to be accessed multiple times natively. 
Unfortunately, DRDB.org does not mention a filesystem to overcome the 
restriction.

Bye.
