Two questions. Are you running a clustered file system such at GFS or OCFS to allow the proper distributed locking required to have multiple systems mount one filesystem? And are you mounting this LUN from the virtual machines or in Dom0 and passing this to each of the virtual machines? – 3dinfluence Aug 25 '09 at 19:34

Standard filesystems (NTFS, FAT, EXT3-2, ...) cannot be accessed by multiple nodes at a time. They are meant to be accessed by a single node and are therefore simpler.

If you need a filesystem to be available by several nodes at block level, you should consider GFS or OCFS. If you need a filesystem to be available by serveral nodes at file level, you should consider NFS or CIFS.

In our company we use XenServer together with StarWind iSCSI SAN. Thus, we did not need to buy a special hardware but turned a generic server into SAN.
