A detailed how-to for getting the drive properly replaced and then the new drive added is located here: http://consultancy.edvoncken.net/ind...oftware_RAID-5
However, if you are getting errors like
'no superblock on /dev/sdb1' when trying to add the new drive to the array, you can try running the following:
Code:
mdadm --create /dev/md0 --level=5 --raid-devices=5 /dev/sd[d-h]1
This will recreate the array, called /dev/md0, raid5 with 5 devices, using disks sdd through sdh, and you can then rebuild it, later accessing the files after having it mounted.
You then need to be sure to update your fstab correctly and your mdamd.conf file.

There are some several very useful suggestions on how to re-add a new drive to the array.

I recently switched to AYK Solutions from Softlayer for my dedicated server requirements. I received a much better specification server at significantly reduced cost from what Softlayer could offer me, with many of the previously 'extra' features at Softlayer included in the base price offered by AYK. The support was second to none, and they were extremely helpful in transferring all of my old server accounts over for no additional fee whatsoever.
I have never experienced a more professional and personal client-based service such as I am enjoying from AYKSolutions. This is no plotted statement either. I'm not a guru by no means, and they have been unbelievably superb in helping me promptly, professionally, courteously, and completely. Thank you Artyom & team.
