Re: [Xen-users] cluster filesystems

Hello Brock

I did a lot of case studies with clustered
filesystems 1,5 years ago and I found out then, that the only usable and
free clustered filesystem that exists for linux is ocfs2. All the rest
isn't cost free or s...

I've you have the monney, go for veritas.

I use GFS on changeset 9029, but it craps out all of the time.  I
get a
lot of soft lockups in the GFS and CMAN drivers, unsynchrnoized GFS
partitions, etc.  I'm hoping that all of the bugs fixed in 3.0.2 will
make things more stable.  (If not, it's bug report time.)  Even
though I
would like to use it as the root partition for all of the VMs, I don't.

I also use NFS on a Xen 2 setup.  That one works fine, but the
performance is awful.
