Logical Volume Woes

[zachsandberg]

Hi everyone.
Tonight I wanted to accomplish my goal of adding a second hard drive to my system. I used the logical volume manager to add my second Cheetah (sdb) to Volgroup 00 as to add room to the / directory. I spent the afternoon reading a few lvm faqs and how-tos and thought I understood the concept pretty good.

Anyway I rebooted, and must have done something horribly wrong as I am now am at the grub> prompt, and cant go any further. Ive manually tried typing "kernel /vmlinuz-2.6.18-1.2868.fc6 ro root=/dev/VolGroup00/LogVol00" but says it cannot mount selected partition.

I dislike having to ask for help or advice, but I am out of options, and wish to not loose data off the drive if at all possible.

I sincerely appreciate any advice.

Update:
I ran the FC6 rescue function on the disk, and came to the rescue shell. Typing LVM -help gives me a list of options. My physical volumes are as follows:

/dev/sda2 VolGroup00 lvm2 a- 34.06G (size) 32.00m (free)
/dev/sdb1 VolGroup00 lvm2 a- 34.16G 34.16G

Typing "vgs" gives me my volume group data:

VolGroup00 2(PV) 2(LV) 0(SN) wz--n-(Attr) 68.22G(Vsize) 34.19 (VFree)

My initial install of FC6 was the default hard drive layout. On one disk only. (sda) I am scared as ***** to merge groups/erase or whatnot without some additional advise from someone more knowlegable.

Thanks Again.
