I recently built an F16 system that had two 80gb drives inside. During the build, I formatted the primary drive with mbr area, /boot, / and swap and left the second drive for later.
After juggling the partition sizes with gparted, now I want to tack the second drive space to the back of the / root partition as a linear 'array' (no redundancy etc.). I have done this before, but this time I can't get started!!!
I checked that mdadm is installed but when I try to launch it, bash comes back to say command not found!?
I was going to do:
mdadm -C --level linear -n 2 /dev/sda4 /dev/sdb1
Anyone able to suggest what went wrong? I have used both yum and packagekit to remove and install mdadm several times.
