Linux software RAID5 can extend a software RAID5 array, by shuffling data around on the existing and new disks, and recalculating the checksums (see the raidreconf command). With hardware RAID5, however, unless your hardware vendor has provided a tool to do this, you're stuck with saving off the data to another location, rebuilding the array, and copying the data back. Maybe the ICP folks can help you, Jeff _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
