Me too (I did in on a real physical SAN before).

GlusterFS is really designed to allow such things... So is GFS. But
these are filesystems...
DRBD isn't really designed to scale this way. A SAN or NAS is.

You are comparing filesystems to storage/mirroring systems. Not a

GNDB is a standard part of GFS. No more patching than GFS or DRBD in
any case... Red Hat and clones all come with support for GFS and
GNDB built in. DRBD is another issue...
GNDB should be known to anyone using GFS, since it is part of the standard
reading (manual, etc) for GFS.

I didn't mean to single you out in my reply... Assume the "you"
is a generic you, not specifically aimed at any one individual...
Sorry if I miss-attributed anything to you... Very busy, and trying
to reply to these emails as fast as I can when I get a minute or two
of time, so I may make some mistakes as to who said what...
I'm not trying to convert or convince any one... I'm just replying and
expressing my experiences and thoughts... If glusterfs works for you,
then great. If not, there are alternatives... I happen to champion
some, others champion others...
Personally, I like SAN storage, but the price has always kept me from
using it (except once, when I was setting it up on someone else's SAN).
