consider you are creating a raid5 device with three drives.
mdadm --create /dev/md0 --leve=5 --raid-disk=3 /dev/sda1 /dev/sdb1 /dev/sdc1
After issuing this command , I can see the progress of md device creating using cat /proc/mdstat.
During the progress ITSELF, can I create a file ssytem partition say ext2 on md0 device like: mkfs.ext2 /dev/md0.
Actually I am able to create this and want to confirm whether doing this before 100% completion of md device creation is CORRECT?
