GFS?
GFS (GFS2 being the supported version) is about multiple nodes using the same shared block devices, pretty much the opposite of what you need. If you want multiple block devices of different sizes in one array then BTRFS is the only option. But RAID-1 is the only level of RAID that should be considered safe with BTRFS at this time. Also this files the "remove one drive" criteria. To satisfy the "remove one drive" criteria you want to have some user-space system for synchronising files by copying them around. Whatever you choose make sure you have checksums, USB devices aren't the most reliable ways of storing data. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/ _______________________________________________ luv-main mailing list [email protected] https://lists.luv.asn.au/cgi-bin/mailman/listinfo/luv-main
