Due to a necessary upgrade to larger disks in a Dell server I'd like to image the existing CentOS 5.3 installation and recover this onto new disks.
Because the existing disks are RAID-1 and take up both slots in the machine I can't simultaneously have the new and old disks in at the same time. It's a Dell R300.
I can take server down and I'm comfortable using rescue disks for CentOS, and creating partitions etc, just a question of the data transfer. It'll likely either be to a USB disk or over NFS to another server (NFS probably preferred, as Gigabit so faster).
I presume this is something like running rsync/tar with the right options on the various partitions - anyone done this and can suggest suitable commands to achieve it?
