I finally got 5.1 to boot after install (install couldn't keep the disk IDs from getting crossed up, so at reboot partitions were not where install said they would be).
I needed to compile vmware and nvidia modules, but decided to upgrade first. Told yumex to upgrade everything.
When I went to reboot the VG with / on it is not seen by the kernel. (root partition is LVM on top of RAID 1). If I go back to the old kernel everything boots fine. On the new kernel only the VG on sdc is seen by LVM.
1. How do I persuade the new kernel to notice the VG with my root partition on it.
2. If #1 is not possible, how do I downgrade kernel-headers to the old version without having to uninstall the dependencies, so I can compile my kernel modules?
+ Original install was network install of 5.1/x86_64 from CD1 (of 7) + VGs were created under Centos 4. + VG DriveAB01 is on md1(sda5+sdb5) + md2(sda6+sdb6), only seen by original 5.1 kernel + /boot is on md0 + VG DriveC01 is on sdc, and both kernels see it + hdd has Win2k on it for dual boot + hdb + hdc are DVD drives + hda is unused + Motherboard is Gigbyte k8n ultra 9 + AMD 3500 Athlon 64 (single core)
