Hi Piotr!
I've used OCFS2 out of oVirt, so I can't tell you specifically about VM
environment, but I suggest you use OCFS2 in place of GFS2. It is simpler
to implement, so less components to configure and it care about fencing
for you.

Hi,
we are developing an application where would be great if multiple host
could have access to the same disk. I think that we can use features
like shared disk or direct LUN to attach the same storage to multiple
VM's. However to provide concurrent access to the resource, there
should be a cluster file system used. The most popular open source
cluster file systems are GFS2 and OCFS2. So my questions are:
1) Does anyone have share disk between VM's in oVirt? What fs did You
used?
2) Is it possible to use GFS2 on VM's that are running on oVirt? Does
anyone have run fencing mechanism with ovirt/libvirt?
Many thanks,
Piotr
