Hi, I tried to preupgrade without a backup from Fedora 16 to 17. Fedora 16 was previously running fine in vmware workstation.

The preupgrade failed trying to unpack the moodle archive and my system is hosed.


1) GRUB menu is frozen at Fedora 16 and immediately boots 16, doesn't let me go up to the Preupgrade entry or down to a previous OS version

2) I get "Welcome to emergency mode"

  2a) If I logon as root, I can continue in Fedora 16

  2b) If I do ^D to continue, it tries to load Fedora 17 and then welcomes me to emergency mode again

Current situation logging in as root to Fedora 16 (case "2a)"):

I can cd to / and see bin, boot, dev, etc, home and so on, and I want to back up /home to a usb drive.

However, when I cd to /home and ls, I get nothing, so I assume I need to mount the drive.

When I mount , I get :

   mount -t ext4 home
   mount: special device /dev/mapper/vg_jsbf16-lv_home does not exist

When I ls -l /dev/mapper, I see three files:


So now what I want to do is get /dev/mapper/vg_jsbf16-lv_home to exist, get a usb drive to mount, and back up the \home directory.

How do I do this?

If your home is not encrypted then just boot Parted Magic live usb and copy what you need (regular file copy).

On a longshot, post what your selinux labels are:

ls -latrZ /dev/mapper/  
ls -latrZ /dev/dm*  
ls -latrZ /dev/sd*  
ls -latrZ /home
