one of our server's drive failed due to power cord issue.
however i plug it back and due to less experience with "parted" i messed the whole thing.
i have 2tbx2 RAID 1 mirror and have 4x500GB partitions.
even i selected the right drive by "select command" and deleted the right partition but parted did something worst though, i take it as my own mistake as i am not that experience with parted i am usually using fdisk.
so the case is. i destroyed 1 partition data. and 3 are still save and accessible. though i do had a backup of the first drive that way things are still in my hand taking all the 3 partitions backup on another drive fore safe side.
now the problem part is i can not re attach the fail drive partition with RAID /dev/md[2,3,4] devices.

please ignore partition 1 of both drives as i already messed them up. however i can not make all other remaining partition back on track as RAID.
when i pass this command.

mdadm: add new device failed for /dev/sdc2 as 2: Invalid argument
i did googled but didn't found something near to my issue. please help.
Thanks
