Re: [Xen-users] EVMS or GFS
There is an easy solution for that (rpm in Mandriva has the same
problem). Create a file on your OCFS2 filsystem, let's say 500M. Setup
loop device and create ext3 fs inside it. Use is as a second disk in
your DomU then and mount it into /var/lib/rpm or whatever Debian uses
for apt-get.
Not the best one, but it works for me with NFS shared device for
DomUs. NFS doesn't support mmap as well

I have tried that at it worked fine, but the problem is that apt-get in
debian uses mmap and ocfs2 does not support that. So I am affried that
that is not an option.
