From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030312 Description of problem: The file /etc/fstab contain the line: LABEL=/ This implies that the apparently mounted partition is not the real mounted partition. The root file system will also not be checked while the system is booting. On my system RH 7.3 was installed on hda2, the complete system was copied to a partition on a new drive (hdd, hdc is a cdrom). df / show "/dev/hdda2 ..." instead of "/dev/hdd7 ..." The size reported correspond to the correct partition. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. install RH 2. create a partition on an other drive and copy the content of the actual system to the new partition, edit the file /boot/grub/menu.lst in order to be able to boot the new "installation" 3. reboot the system with / at the new partition. Actual Results: see description, Expected Results: correct information about the real mounted file system Additional info: The idea of using LABEL=/ within /etc/fstab is good but the boot process work not correctly. Modifying the lile "LABEL=/ ..." with e.g. /dev/hdd7 / ..." solve the problem but is not as pretty as the original line.
If you copy and are using a new root fs, then you need to update the label on the destination partition as well. The label is set in the filesystem superblock, it's not really very deep magic.
