You can, if you connect the iscsi block devices into one machine that can combine them in one or more md raid devices, put a filesystem on them, and export via nfs and/or smb to the systems that want shared space. However, the
If you did this, took a handful of machines, exported their storage via iSCSI and had a single server taking each of those iSCSI exported drives and combining into a single giant md device, would the theory of redundancy still hold?
Say, I had 4 devices with 500 GB drives exported using iSCSI. If a single larger server took those four iSCSI export drives, and created one md RAID 5 device, could a single server be turned off, and just degrade the array until it was either replaced entirely or brought back online?
I suspect so. After all, it is just seen as a disk as far as md is concerned and it will do the same normal thing if you unplugged a single disk from the array.
