Hi Eduardo,
yes fencing method used in OCFS2 is probably better for vitalized
environments. Thanks for advice!
Many thanks,
Piotr

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
