Oracle Linux Fails Booting With "fsck.ext4: No such file or directory while trying to open /dev/mapper/vg_XXXXXX-lv_root"
Last updated on JULY 07, 2018
Applies to:Oracle VM - Version 3.3.3 and later
Linux OS - Version Oracle Linux 6.0 and later
The Linux system doesn't boot and messages like the following are shown on the console:
fsck.ext4: No such file or directory while trying to open /dev/mapper/vg_XXXXXX-lv_root
Possibly non-existent device?"
The system then offers to enter the root password to get into maintenance mode.
In maintenance mode, a df does show the device, but ls /dev/mapper doesn't show the root and swap device links but other logical volumes on the group are shown (if any).
ls -al /dev/mapper/vg_XXXXX-*
lrwxrwxrwx 1 root root 7 Jun 20 16:40 /dev/mapper/vg_XXXXX-lv_home -> ../dm-2
lrwxrwxrwx 1 root root 7 Jun 20 16:40 /dev/mapper/vg_XXXXX-LV_oracle -> ../dm-3
