BUT the md2 is showing on one [U_].. that means my root partition is not properly in RAID 1..
Please suggest how can i make it active in both drive. Or i need to reinstall complete system again. Screen shot attached
If I try to make the raid again with command...
$ mdadm /dev/md2 -- add /dev/sdb1
then it give error that
mdadm: Cannot open /dev/sdb1 : Device or resource busy
How can i manage to get the raid back on the root partition.
