Hi Guys,
I have a server running CentOS 4.2 with a 2.6.9-22EL-smp kernel.
Why not run a fully updated centos-4?
The system contains a 2.3 TB RAID 5 array. There is a 20GB root partition with the remainder of the drive configured one large LVM volume. (/u0) ... I cannot do any of the following to the backup file: Use cat, dd or cp to copy the file. The first part of the file aproximately 24MB will copy and then I get the error message: Input/output error
Booting from it implies that you have a "normal" partition table on the 2.3T device, this does not work (dos style MBRs only works with <2T). Most people boot from a small and independent device and uses gpt (see parted) on the big device or no table at all (lvm directly on the device).
Good luck, Peter
