I feel sorry for you. But welcome to LQ anyway
Things like "Virtual Machines" and "Volume Groups" scare the pants off me - I like to keep it all SIMPLE, and rather old-fashioned. Then when things go wrong, it's easy to fix, without all the layers of abstraction and virtuality. Maybe I'm just a linux-coward.
I wouldn't be posting this except you have already answered your own thread yourself (so it is no longer "zero-replies"), so I now view it as a free-for-all rather than "wait for someone who knows what they are talking about" to post the first answer. 'nuff said
If you are in a mess and a muddle, the best thing to do is boot from a "Live CD" distro. Knoppix is famous for this, and kubuntu does very well too, but there are others. Maybe even your own distro's disk will do this (I am not familiar with FC).
Boot and run from that
live CD. Do
not install. (It'll be a little slow to start applications, as you haven't installed it to a HDD, but no matter, we are desperate). Mount your problematic disk. Sort it out.
Unmount the disk. Reboot (without the CD).
Alternatively, you
may be able to boot from the (nearly full - but some emergency spare space is always reserved for the root user, just in case this happens) HDD by choosing "Recovery Mode" from grub's (or lilo's) menu - this'll boot to a text terminal with root priviledges. You get no GUI, but you can fix things up from the terminal (I hope you know how to use a terminal editor like
vi or even
nano, and are familiar with
bash basics).
You might be able to do something simple (eg
rm -rF /usr/src/linux*) to free up enough space for you to be able to boot normally. You can always restore
/usr/src/linux* (If you have made a note of what was there before you deleted it!) when you have migrated to a bigger disk, and you won't be needing it meanwhile, as you will not be installing any new software until this is fixed.
Oh and your mount command may break something unless you first create a mountpoint:
Code:
mkdir /mnt/mountpoint
mount -t ext3 /dev/VolGroup01/LogVol00 /mnt/mountpoint
But then I know
nothing about VolGroups
Hope this helps.
