Depends on how you set it up, if you have 2 machines ( disk nodes ), exporting iscsi. 1 machine ( data node ) doing the import and sets up a raid1; you can afford to have one of those two machines down. You *cant* afford to have the data-node down. Thats where the filesystem lives. You can potentially have the same disks from the disk-nodes imported to a standby data node using something like drbd over the mdraid setup. Alternatively, you can look at using a clustered filesystem and have it go X way. But then you may as well use something like gnbd with gfs2 instead(!).
Looking up gfs2 was what lead me to glusterFS actually and because glusterFS had all the RAID stuff pointed out upfront, I stopped reading about gfs2. Googling gluster then lead to openFiler which then seemed like a simpler way to achieve the objectives.
No acls on Gluster...but I suppose you have no need for acl support...
