RAID 1 Error
 
1 Attachment(s)
I had just configure RAID 1 on my IBM X3400 Server ..Partition information is md0 boot , md1 swap and md2 is root ....but after resyn when i run cat /proc/mdstat I realize that md0 and md1 is ok and present with [UU] status. 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.

You appear to have some kind of error. What are the outputs of
Code:

mdadm --detail status /dev/md2 and cat /proc/mdstat
