CentOS packages DRBD in -extra.
http://mirrors.ircam.fr/pub/CentOS/5.2/extras/x86_64/RPMS/

Ubuntu has it, including the 8.04 LTS :
http://packages.ubuntu.com/search?suite=hardy&searchon=names&keywords=drbd

Gentoo has it :
http://packages.gentoo.org/package/sys-cluster/drbd

As others have already pointed out, it seems present in all if not all
major distributions used in any server role. Having it in Fedora/RHEL
would provide us with a very nice SAN-like capability (coupled with
iSCSI target support).

I've used the CentOS-extra package in master/slave replication as in :
http://www.drbd.org/home/mirroring/
It also supports master/master but I've never needed it and it's not
recommended to use it anyway.

I am seriously considering to use it at work to replicate about 2TB of data
(Xen VMs) accross a 4x1Gb/s aggregated link.
I have not been able to fault it yet and I will probably have more results
in the coming weeks.
