I typed the following three commands first: [liveu...@localhost ~]$ su - [r...@localhost ~]# kpartx -av /dev/sda [r...@localhost ~]# vgscan [r...@localhost ~]# vgchange -ay After that i run the following command: [r...@localhost ~]# ls /dev/mapper the output of which was: control live-osimg-min live-rw VolGroup-lv_root VolGroup-lv_swap [r...@localhost ~]# mount /dev/mapper/VolGroup-lv_root /mnt/oldfedora/ after that switched to the /mnt/oldfedora/ [r...@localhost ~]# cd /mnt/oldfedora and run the ls command [r...@localhost oldfedora]# ls which yielded: bin dev home lost+found mnt proc sbin srv tmp var boot etc lib media opt root selinux sys usr Means i got to that area. The output of the following command: [r...@localhost oldfedora]# cat /etc/fstab was: # # /etc/fstab # Created by anaconda on Tue Jul 6 16:51:55 2010 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or vol_id(8) for more info # # Adding (append) noatime, nodiratime after all 'defaults' entries in the following (back of this file already taken)( http://digitizor.com/2009/01/31/fedora-speed-tweaks-make-fedora-faster/) # See http://sites.google.com/site/indiadoor/home UUID=c6d4ce29-9af6-4c76-bbd2-c96e3fa4b8e7 /boot ext3 defaults, noatime, nodiratime 1 2 /dev/mapper/VolGroup-lv_root / ext4 defaults, noatime, nodiratime 1 1 /dev/mapper/VolGroup-lv_swap swap swap defaults, noatime, nodiratime 0 0 tmpfs /dev/shm tmpfs defaults, noatime, nodiratime 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 #devpts options modified by setup update to fix #515521 ugly way sysfs /sys sysfs defaults, noatime, nodiratime 0 0 proc /proc proc defaults, noatime, nodiratime 0 0 # Filesystem can be used for frequently use temp folders by add the following lines ( http://digitizor.com/2009/01/31/fedora-speed-tweaks-make-fedora-faster/) tmpfs /tmp tmpfs defaults 0 0 tmpfs /var/tmp tmpfs defaults 0 0 I don't understand why it is wrong? But after much pondering over, I just deleted the gap between the nodiratime,noatime and defaults, and really speaking after that only i was able to boot from the original fedora. > ---------- Forwarded message ---------- > > > > > From: Marko Vojinovic <vvma...@gmail.com> > > > To: users@lists.fedoraproject.org > > > Date: Sun, 18 Jul 2010 19:50:22 +0100 > > > Subject: Re: Can one now help? > > This is 100% correct.
