FSTAB Missing... Can't boot in Fedora Core

So I started this job around 2 months ago and even though this Software Development company had been around for 7 years they have never had someone hired on whose main duty was System/Network Administration & Network Security. So needless to say having a couple different people randomly doing things when they need to be done creates a huge unorganized mess after 7 years.

So besides trying to move into a network & organize everything as well as learn what's going on I'm having to deal with things that just quit working for no apparent reason except probably it was setup by someone who doesn't know what they're doing.

So anyways, we have this server that's running our wiki database, our bot controller, as well as some other random things. But last week most of the services on it went down so after some looking around I found that it had run out of space. It was using LVM file system and to tell you how long ago this was setup it was running Fedora Core 2 and was on a 160GB Sata 1.5 hard drive. Holy crap... It's also in some ancient dell tower which was sideways sitting on top of a switch that was mounted in the rack. ohhh me I have too much work to do here.

So anyways I cloned the disk over to a 1.5 TB drive and attempted to extend the Volume Group... I asked around on here and the directions I got seemed to match up with ones on other websites. I did the commands and I think I must have forgot something that has to do with fstab because now I'm getting this message upon boot...

Reading All Physical Volumes.... This could take a while.

Couldn't find device with UID FKTS-etc etc... (I'm guessing this is because I changed hard drives..)

Couldn't find all physical volumes for volume group

Now even when I try to boot into Fedora Rescue CD it looks for old Linux Filesystems and says it didn't find any linux partitions and that it would restart after I exited the shell.

The shell came up as sh-3.1#

I tried to mount /dev/sda and it says couldn't find /etc/fstab

Sure enough... /etc/fstab is not there. It doesn't seem to mount my disk for use anywhere... I don't know how to fix this issue. I get the grub loader when I boot the computer and everything.

If I do the fdisk -l command I get this...

Device    Boot              Start              End        Blocks      Id       System
/dev/sda1    *                     1            13024   31257568+  83        Linux
/dev/sda2                     13025         78084  156143767+  8e        Linux LVM
/dev/sda3                    130238      130238   125169600   8e        Linux LVM


So this is obviously on the new drive... (I accidentally left the old one I had cloned it too plugged into SATA and accidentally ran some commands that well... Also ruined the VolGroups. I'm awesome I know)

So /dev/sda3 was made by me following the directions I got. I created it with the rest of the unpartitioned space. Here are the commands I did... (Well pretty sure I did... maybe I left one of them out and that's why everything is messed up)

This is the output on the guys computer... So he's doing sdb and I had sda etc.. You get the drift.

Step 1: Create a new physical volume to take up all that lovely free space

# fdisk -u /dev/sdb

You can just accept the default values like I did, thats why it shows no reply to some of the questions, I just pressed enter and it will make a new partition that takes up all the space.

Step 2: Create a new PHYSICAL VOLUME for use with your VOLUME GROUP.

bob:~ # pvcreate /dev/sdb2
  Physical volume "/dev/sdb2" successfully created

If you receive an error about ignored by filtering, reboot your machine and try again.

Step 3: Add new volume to volume group

bob:~ # vgextend VolGroup00 /dev/sdb2
  Volume group "VolGroup00" successfully extended

(My volume group has a cool name, but I put yours in so you can copy and paste)

Step 4: Add space to the logical volume you want. Probably your root one LogVol00

bob:~ # lvs
  LV   VG   Attr   LSize  Origin Snap%  Move Log Copy%  Convert
  root pc   -wi-ao 53.23g                                      
  swap pc   -wi-ao 12.00g                                      

Those show mine, you want to add space to LogVol00 though so you go:

bob:~ # lvextend -l +100%FREE /dev/mapper/VolGroup00-LogVol00
  Extending logical volume root to 99.72 GiB
  Logical volume root successfully resized

bob:~ # lvs
  LV   VG   Attr   LSize  Origin Snap%  Move Log Copy%  Convert
  root pc   -wi-ao 99.72g                                      
  swap pc   -wi-ao 12.00g                                      
bob:~ #


So that's what I did or am pretty sure I did.

So any help at least telling me what I did wrong would be cool.

Also... now since I accidentally jacked my original install I still have it on a 1.5TB drive but the only issue is I told clonezilla to make the filesystem use the rest of the free space for the partition and now /dev/sda2 on that drive takes up all the space, but it's still saying it has 0 disk space. So I need to either make sda2 see all the rest of the space or extract all the information and somehow get it working properly.

Thanks in advance... This topic seems to always take a lot of work for both the person answering and myself. Lol
