Hi all,
I hope to reshape a RAID10 (near,2) with 2 failed and physically
removed members [_U_U] into a RAID1 hopefully [UU], for the
benefit of seeing a healthy status.
Is following proposed invocation correct?
mdadm --grow /dev/md2 --level=1

root@mencius $ mdadm --query --verbose --detail /dev/md2
