Hi!
First, sorry for the wall of text I tried to be thorough.

We got a sun x4540 with CentOS 5.8 x64 full with 1TB disks. One of the OS disks reported smart errors so we asked Oracle for a replacement.
First added a spare disk ( /dev/sds{,1,2,3} to md{,0,1,2} ) and let them rebuild by failing and then removing /dev/sdi devices, however after rebuild we decided to change back to the same device id as it had before ( /dev/sdi instead of /dev/sds - this because /dev/sdi is already in device.maps).
To copy partition table we ran "sfdisk -d /dev/sda|sfdisk /dev/sdi"

Howdy, Stranger!
