I'm running into a kernel panic when I change the VolGroup that the system is in. I'll go more into how I do this in a minute. But the reason I do it is that I must take a hard drive out of another system put it in another system so the data can be copied. I have 9 systems that have the default lvm install config. The 9th system is used to put the harddrives from the 8 systems one at a time to read the data from the drives. I'm trying to change the VG VolGroup00 of system 9 to VolGroup99 so that I can mount the other system with VolGroup00 when I need too. Hopefully, with a usb adaptor or something of that sort. What I do is boot system 9 with the Rescue CD and do a # lvm vgchange -a n and then # lvm vgrename VolGroup00 VolGroup99 and I get a success message that the VG has been changed. I test mount the lv and I can read and write data fine. I then reboot the system edit the line in grub on bootup to VolGroup99 and get the kernel panic message below the line. I'm using RedHat Enterprise Linux WS 4 Update 4 with kernel 2.6.9-46.ELsmp which I found from the message forums. Is their some sort of config I'm not changing that I'm supposed too? I thought the kernel update I applied was supposed to fix this.
