400. Centos/RHEL 7 - Fix LVM boot issues after migration from ESXi to VirtualBox 2018-04-20

     tags: boot, bootloader/grub, filesystem, filesystem/lvm, fstab, linux, linux/centos, linux/kernel, linux/red-hat

     [ permalink ]

     Here are the steps I used to migrate a CentOS 7 VM from (presumably?) an ESXi server, to a local VirtualBox environment.

     The LVM volumes were not detected at boot, and after the boot timeout, the OS fell back to the Dracut emergency shell.

     • get a CentOS minimal installation CD
     • check the VM's resources and peripherals:
       • ensure there are no floppy drives (!)
       • setup CPU and RAM resources
       • check virtual drives
       • add an SCSI optical drive if needed
     • optional: convert the virtual drive images from VMDK to VDI
     • mount the CentOS installation disc
     • boot on the installation disc:
       • select "Troubleshooting", then "Rescue"
       • let the rescue utility detect filesystems and mountpoints
     • $ chroot to the detected environment
     • backup files:
       • /etc/fstab
       • /boot/grub/grub.cfg
     • under /boot, backup the initrd and initramfs for the current configuration (these will be overwritten)
     • compare the current /etc/fstab with the output of $ lsblk and $ blkid
     • if needed, manually edit /etc/fstab to use the appropriate block device UUIDs, identifiers and mountpoints
     • regenerate GRUB configuration:
       • $ grub2-mkconfig -o /boot/grub2/grub.cfg
     • if needed, reinstall GRUB:
       • $ grub-install /dev/sda
     • rebuild initrd:
       • $ mkinitrd --force /boot/<initrd_image> <kernel_version>
     • rebuild initramfs:
       • $ dracut --force <kernel_version>
     • exit the chroot
     • unmount the installation disc
     • reboot
     • optional but highly recommended: cross your fingers
     • ...
     • profit!
