Replacing a Raid disk
 
Hi All

Been playing with software raid 1 using this document
https://help.ubuntu.com/11.04/server...tallation.html

I have built it and all works fine. I have removed a disk and installed another 1 but what I need to know is how do I partition the new disk using the command line ready to add back in to the array

Thanks

Glenn

Just clone the partitioning of the first drive to the second drive, you can use sfdisk for that:
Code:
sfdisk -d /dev/sda | sfdisk /dev/sdb
Assuming here that sda is the old disk and sdb is the new one, change according to your situation.
Warning: Double check the drive names, or you may destroy the partition table of the old disk
