Hi All, After restoring data from a backup image set for a 500GB harddisk to a 1000 GB harddisk, I am unable to boot up my F11 OS. I have already restored *both* the MBR backup and the dump output from sfdisk. What else is missing? I am stuck at a blinking cursor at the top left corner of the screen. GRUB is not loading and I am unable to select any kernel to boot. Using System Rescue CD, I am able to activate all the logical volumes and all the volume groups that were restored. I am also able to mount all the logical volumes and access the restored filesystems. So I think the filesystems are restored properly. So I think it is the problem with MBR, sfdisk dump output restoration, or GRUB. Is there a problem with restoring data of a 500 GB harddisk to a 1 TB harddisk?
Well, let's see...the geometry between the two disks are going to be different so the partition table's going to be screwed up. That may cause an issue with grub. It's always dangerous to use block-level backups and restores when the drives are of different sizes or geometries. I'd recommend you boot off the DVD in rescue mode, then use fdisk and the other tools to verify that the partition tables are in good shape. You should also probably fsck each filesystem just to make sure. Once all that's done, you may have to rebuild the grub environment: chroot /mnt/sysimage grub-install /dev/sda (or whichever disk it is) exit (gets out of the chroot) exit (gets out of the rescue boot) Pop the DVD out and try to boot again. That may fix it. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer ricks@xxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - We have enough youth, how about a fountain of SMART? - ---------------------------------------------------------------------- -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
