RAID 5 assumes equal sized disks. If you insert larger disks only the first 250 GB will be used - smaller will not work. Your best bet is backup, replace the disks, build new array and restore. If you have 3 open slots I can imagine a scenario where where you start a new RAID 5 (2 TB), migrate the data, delete the old 250GBx6 array and expand the new array one disk at a time. If you only have 2 extra slots, build a RAID 0, migrate, remove the old disks, build a new RAID 5 (4 disks), destroy the RAID 0 and add the disks to the RAID 5 one at a time. But backup first. -- George Bourozikas _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
