No, it just manages volumes.

ext3 is fine if it won't be mounted by two things at once. If it's
mounted read-only by every mounter, ext3 can be shared.

If you want to export the DRBD block device to the network, you can use
iSCSI, AoE, GNBD, etc. It would still have LVM volumes on it, though.
It would probably be easiest to use RHCS stuff (CLVM, GNBD, and GFS)
together. They all use the same locking system and configuration.
