...llation DVD, with an already existing CentOS 5.5 system on my hard disks. I have separate boot, root, and home partitions. I have moved the boot partition and now I need to re-initialize grub from rescue mode. Attempting to use 'rescue mode" to automatically mount my system under /mnt/sysimage eventally fails with an error message, which essentially says 'mount error' and nothing else. I am then put at a command prompt as root. So now I decide to manually mount my partitions at /mnt/sysimage and then do a chroot to /mnt/sysimage. This succeeds and when I look at my files the...

If I boot C5 from DVD in rescue mode, chroot to /mnt/sysimage, and try to do a grub-install /dev/sda it will fail because the /dev folder is empty (in the chroot environment). Until now I've then created the missing nodes manually, but is there a smarter way of doing this? Some devfs that needs to be mounted on top of /dev? Mogens -- Mogens Kjaer, Carl...

On this URL: http://www.centos.org/docs/5/html/Installation_Guide-en-US/s1-rescuemode-boot.html there is a description of "linux rescue" which includes the following: From the prompt, you can run many useful commands, such as: ssh, scp, and ping if the network is started dump and restore for users with tape drives parted and fdisk for managing partitions

...mounted. When I boot from the install DVD and type "linux rescue" I eventually get the message, after attempting to have one of the screens mount my partitions in read/write mode: "An error occurred trying to mount some or all of your system. Some of it may be mounted under /mnt/sysimage." But nothing appears mounted under /mnt/sysimage. Does anybody have any idea of why this error is happening ? Should I try mounting my CentOS 5.5 partitions manually at this point ?

Hi all, I had the same problem with my UEFI bios machine and I fixed it so for Centos 7: 1) Boot from an rescue linux usb 2) When the rescue system is running: ??? 2.1) #chroot /mnt/sysimage 3) Config network: ??? 3.1) # ip addr add X.X.X.X/X dev X ??? 3.2) # ip route add default via X.X.X.X??? <--- default router 4) And finally: ??? #yum downgrade shim\* grub2\* mokutil ??? #exit ??? #reboot I hope you can fix it with these steps.

Sorry, I am not an expert, but it does seem to NOT be under tmpfs: Filesystem Size Used Avail Use% Mounted on ... /dev/vdal 497M 192M 306M 39% /mnt/sysimage/boot ... Why do you say that the boot partition is under tmpfs? Nick

I had to unmount the boot partition (being in Troubleshooting mode), run the above command, which provided a new UUID and at last the partition was recognized as xfs. (I forgot to copy the output to paste here.) I then mounted the boot partition again, chrooted, grub2-install'ed successfully,

Hi Updated the firmware on a PERC RAID card as it was out of date and causing a monitoring error - Everything went fine but on the reboot the box now tells me it cant find a valid boot device - I am thinking maybe somehow the boot block on the logical disk is shot. Can anyone advise me on how to rebuild the bootloader on lilo using a rescue CD? thanks

...l 2 days back. Suddenly when the PC was booted-up, it wouldn't bootup. It gets stuck displaying the following message. exec of init (/sbin/init) failed !!!: 80 umount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init! I entered the rescue mode and attempted chroot /mnt/sysimage It spitted an error "chroot : cannot execute /bin/sh: Accessing a corrupted shared library." I tried to google-out the problem in vain Any clues as to whats the problem and the remedy? TIA, Balaji
