Yes and no. You can only mount an ext2fs disk on one of the connected machines at once if you have multi-ported disks. However, if you have control software running at a higher level, there's nothing to stop you from dismounting on one and remounting on another, or mounting on one machine if another dies.
Bear in mind that until we have the ext2fs journaling work finished, remounting the filesystem like that after a system failure will require the pain of an e2fsck, and you'll have to be careful to flush the buffer cache before remounting such a disk.
