Hello, Software RAID has the same limitation as LVM1 as it's not cluster aware. Even with LVM2 you have to use CLVM to make sure the appropriate cluster wide locking takes place before touching the metadata on the disk. Software RAID has no cluster awareness, so you could run into the same problem you would have if you mounted an ext3 filesystem RW between two nodes, you would end up with corruption. This isn't a limitation with GFS, but more a limitation with md RAID, as its not cluster aware.
