GULM is 1 option, DLM is another. I have been using lock_dlm
(distributed lock manager), along with cman (Cluster manager). It
ships standard with Centos, and also have it running on Gentoo.

Yes. Dont need a GULM server if you are using dlm though.

Centos modinfo on gfs also shows gfs2 as dependancy. locking is a
seperate service from gfs, and from what I understand, both gfs and
gfs2 use locking (lock_dlm). Not sure why there is this module
dependancy. Have no idea why there is this depedancy though.
