I was wondering what people use / recommend for a cluster fs for use with xen ?

We use GFS.

Also with this cluster fs, will the domU's be using flat files / lvm ? (it should be the former as per my guess since these flat files will be stored on the cluster fs, but then won't performance hit will be there for these domU's ? )

We use CLVM.
I hear talk of CLVM, but I'm trying to understand what the difference is between CLVM and normal LVM, where the CLVM software is and what I have to do to turn my LVM system into a CLVM?????

I'd also be interested to know if you can combine CLVM with a dm-raid solution, to create a clustered raid device? I understand that dm-raid0/1 has been released, and there's a dm-raid4/5 in alpha at the moment.

Thanks,

Tony Wright.
