i am using 2 local disk, exported via vblade (i have an aoe storage, this is the test environment).

on top of that right does not matter for me which fs, cause it will be used also by xen hvm (let say also ntfs).
anyway, tested with ext3 and reiserfs.
(but i think i will get a RTFM as you write down your questions ;( )

the tricky part is in lvs, i can see an open volume in pvsrv07 and not in pvsrv08.
