I did search the H3LL out of google and nothing came back on what Im attempting to do……. <o:p></o:p> <o:p> </o:p> <Novel><o:p></o:p> <o:p> </o:p> I really need some insight on this one as Im very confused as to why my Dual boot system is not working. I am attempting a dual boot OS with RHEL 4 and FC5 using Grub Boot loader. I have attempted several configurations trying to sort this out and have ended with the following and don’t understand why this wont boot.<o:p></o:p> <o:p> </o:p> I have created 3 partitions (I created the sda3 for FC5 via the FC5 installer through an NFS install, not sure if that matters or not):<o:p></o:p> <o:p> </o:p> /dev/sda1 as /boot<o:p></o:p> /dev/sda2 as PV 1 aka VolGroup00<o:p></o:p> /dev/sda3 as PV 2 aka VolGroup01<o:p></o:p> <o:p> </o:p> Under both of the VolGroup’s I have created two Logical Volume’s:<o:p></o:p> / aka VolGroup00/LogVol00<o:p></o:p> SWAP VolGroup00/LogVol01<o:p></o:p> <o:p> </o:p> And<o:p></o:p> <o:p> </o:p> / aka VolGroup01/LogVol00<o:p></o:p> SWAP VolGroup01/LogVol01<o:p></o:p> <o:p> </o:p> I installed RHEL 4 first under VolGroup00 (/dev/sda2 – booted fine) and then installed FC5 under VolGroup01. I was expecting Grub to pick up the new install and just create a new Stanza that referred to the newly installed VolGroup01 (FC5). By default FC5 came up and apparently over wrote the grub.conf file with only the FC5 Stanza pointing to VolGroup01. FC5 boots fine but RHEL4 does not. When I altered the grub.conf file to have the older RHEL4 Stanza and attempted a boot the boot process threw a kernel panic attack. I thought it might have something to do with the LABEL and attempted the boot with the partition name (/dev/sda2) and still received the same kernel panic attack.<o:p></o:p> <o:p> </o:p> After examining the fstab file on the FC5 instance I noticed that my VolGroup00/LogVol00 entry for my original RHEL 4 / LABEL was removed. I was actually expecting to see two entries here, one for the VolGroup00/LogVol00 for RHEL4 / and one for the VolGroup01/LogVol01 for FC5 /. Instead I only saw the FC5 / entry. I asked a colleague of mine about this and he mentioned that I could not use the RH install Wizard to create multiple LV / partitions under the same VolGroup and that I needed to do it manually using lvcreate, mk32fs and then e2label labeling the newly create LV as /. This approachdid in fact work, but Im still not sure why my original approach didn’t. Im very confused as to why neither approach has worked for me. In theory a machine with 3 partitions as described aboved should render two PV’s and essentially two bootable OS’s, shouldn’t it???? Do you really need to have all / partitions for both OS’s under the same VG? Wouldn’t two separate VGs with the same <st1:City><st1:place>LV</st1:place></st1:City>’s (/ and SWAP) perform the same task???<o:p></o:p> <o:p> </o:p> </Novel><o:p></o:p> <o:p> </o:p> Any explanations here is greatly appreciated!<o:p></o:p> <o:p> </o:p> Thanks,<o:p></o:p> <o:p> </o:p> Interp01<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> <o:p> </o:p> </div> </body> </html>
