Hello All,
I have a machine that crashed. Some part of the motherboard (power supply-related) went south.
The motherboard, CPU and memory have been replaced with a much newer architecture. The OS and data are intact on two SATA drives that were RAID1 with LVM.
I am going to use 'linux rescue' to recover the LVM backup so I can mount the RAIDs (there were two) in a new CentOS install, on a third disk.
I have no indication that I could recover the previous CentOS (somewhere between CentOS 5.1 and 5.2 on updates).
Can I use 'linux rescue' to fix that OS up to boot it? The kernel panics in its current state (because the hardware architecture is so strikingly different). What is the methodology of fixing the kernel in this circumstance?
I don't know that this will be a major problem if my experience years ago going from Caldera OpenLinux something-or-other to SuSE Pro was any example. The old Caldera system had a multi-disk LVM RAID which I had moved to a newer system, fully expecting to lose the data after installing a new Linux OS on the system.
I did a fresh install on the primary HD without touching the external RAID drives, and, much to my surprise, the new Linux found the RAID drives, asking if I wanted to mount them.
