Do a 'cat /proc/mdstatus' and check whether md still thinks you have two hard disk in the raid setup. 2. Assuming it shows three or more hard disk with one in failed status. Run 'mdadm /dev/md0 -r /dev/hdd1' which should remove the failed device from the RAID array. 3. Run 'mdadm /dev/md0 -a /dev/hdd1' which should add the new hard disk back into the array. 4. Regularly check the output of 'cat /proc/mdstatus' to see the Raid array being recreated. If possible try not to shutdown the server till the array is recreated. Following command might be helpful 'watch -n 10 cat /proc/mdstatus' 5. RAID devices dont necessarily have a filesystem therefore you can't mount the device/array itself. Assuming your filesystem didnt get wiped out you should not have to mount anything. RAID will recover itself and become healthy in the background without your intervention. Ofcourse system performance would go for a toss meanwhile. Do note I have made assumptions as to what your devices and raid setup are. Check the man page to understand what options I have given and their implications. Mithun __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
