Help!
I used "yum update" updated my system the other day, then I
restarted
the computer, but it couldn't get in!
So I used the DVD containing Fedora ISO to rescue the system, but I
still saw nothing in /home/houghes which stores all my important
files!
But then my first aim was to get the system up, and I used the DVD and
chose "update existing sytem" hoping to get back to the point where I
hadn't updated Fedora using "yum update". Though this is not the
result, I got it!
But I still couldn't see anything in /home/houghes !
And since the system start-up process is so different from before, I
covered /boot/grub/grub.conf with /boot/grub/grub.conf~ , and the
start-up is normal now!
But how Can I Get My /home/houghes data back?! Help!

Is it possible that /home was on a separate partition and isn't mounted?
what do you get when run
the following commands?
fdisk -l /dev/sda
mount
Craig
following is got by running fdisk -l /dev/sda and mount:

/dev/sda2 ought to be the partition I seperated for /home,
and /dev/sda7, /dev/sda8 are seperated for /usr/local and /tmp
respectively, so I tried to add three lines in /etc/mtab for them as
follows:
/dev/sda2 /home ext3 rw 0 0
/dev/sda7 /usr/local ext3 rw 0 0
/dev/sda8 /tmp ext3 rw 0 0
and in /etc/fstab as follows:
UUID=61b8990c-043e-4d1f-9a37-7f330cc49eb5 /home
ext3 defaults 1 1
UUID=0cf03423-386b-407b-a60b-54c076692d77 /usr/local
ext3 defaults 1 1
UUID=d8297ee9-bd48-4b2c-a81a-ba0afdf42d0d /tmp
ext3 defaults 1 1
but my files in /home/houghes still don't come out!
What should I do?
----
first, take a looksee at /dev/sda2 and see if that really is your
old /home...
mkdir /home/oldhome
mount /dev/sda2 /home/oldhome
ls -l /home/oldhome
if it is, you can figure out the UUID of /dev/sda2, probably just by
doing...
# ls -l /dev/disk/by-uuid/
and putting that UUID into /etc/fstab for a /home mount
I don't think that editing mtab is going to be useful.
May I suggest 'blkid' for stuff like this? Far easier to understand.
