All, I have yet to find THE definitive word (via any search and forums) if this is possible; expanding a raid0 set by adding drives. (Please, I know there is no redundancy, and that is fine as these volumes are really Amazon WS EBS volumes, so we only strip for speed improvements) It seem this works: more /proc/diskstats mdadm --create /dev/md0 --chunk=256 --level=0 --raid-devices=2 /dev/sd[b-c] mdadm --detail /dev/md0 mkfs.xfs /dev/md0 mount /dev/md0 /mnt vi /mnt/test umount /dev/md0 mdadm --grow /dev/md0 --level=0 --backup-file=/tmp/grow --raid-devices=3 --add /dev/sdd <= changes to raid4 mdadm --detail /dev/md0 mdadm --grow /dev/md0 --level=0 --backup-file=/tmp/grow <== changes to raid0 mdadm --detail /dev/md0 Can someone please confirm this correct and that raid0 can be expanded, or is there a better means to expand an raid0 raid set?
