The safest option would be: - add in the new disks - partition to at least the same size as your existing partitions (they can be larger) - add the new partitions into the arrays (they'll go in as spares) - grow the arrays to 4 members (this avoids any loss of redundancy) - wait for the resync to complete - install grub/lilo/syslinux to the new disks
Ok.. got here.
- fail and remove the old disk partitions from the arrays
Now.. I may need some guidance for the next steps.. please correct me if I'm wrong..
to fail the old disk partition from the arrays I should: mdadm -f /dev/md0 /dev/sda1 mdadm -f /dev/md1 /dev/sda2 mdadm -f /dev/md2 /dev/sda3 mdadm -f /dev/md0 /dev/sdc1 mdadm -f /dev/md1 /dev/sdc2 mdadm -f /dev/md2 /dev/sdc3 and to remove the old disk partition from the arrays I should: mdadm -r /dev/md0 /dev/sda1 mdadm -r /dev/md1 /dev/sda2 mdadm -r /dev/md2 /dev/sda3 mdadm -r /dev/md0 /dev/sdc1 mdadm -r /dev/md1 /dev/sdc2 mdadm -r /dev/md2 /dev/sdc3 correct?
- shrink the arrays back down to 2 members
to shrink the arrays back down to two members: mdadm --grow --raid-devices=2 /dev/md0 mdadm --grow --raid-devices=2 /dev/md1 mdadm --grow --raid-devices=2 /dev/md2 correct?
