Hi,

An older Proliant DL-145 server is installed using Linux software raid
on a 40 (primary) and 80 gb disk (secondary). Strange and not an
efficient setup, so we want to re-place the 40 GB disk with an 80 GB
disk and also resize one partition to use the full 80 GB. After some
googling and faq reading, this seems to be an option :

- make sure grub is also setup on the old 80 gb disk
- remove the 40 gb disk from the array with raidsetfaulty and
raidhotremove
- shutdown the system and replace the 40 gb disk with the new 80 gb disk
- boot from CD and repartition the old 80 gb disk
- boot the system from the old 80 gb disk
- safe partition layout to file : sfdisk -d  /dev/hdb > partitions.file
- partition new 80 gb disk : sfdisk /dev/hda < partitions.file 
- add new 80 gb disks partition to the raidset

We have a backup so the removed partition can be restored ;)

Any ideas or comment is welcome!

Cheers,
Andre
