How can I grow my existing software raid 1?
In my system there is a s/w raid 1 /dev/md1 with /dev/hda2 and /dev/hdb2 and mounted on "/".Now /dev/hda2 has been failed and removed from the array.
The capcity of the array is 40GB and I want to extend this to 80G by adding another 40GB HDD. In current scenario there is no more raid1, and I am not going for the raid 1 again. My only intention is to grow the /dev/md1 upto 80GB. Is it possible with
mdadm --grow command??
Help me please !!
Output of mdadm --detail /dev/md1
