Cannot read superblock on /dev/mapper/<VG>-<LV>
After an in-place restore of an OCI instance, if the LVM was created as part of the disk partition, then the LVM cannot determine the state of the volume group, and the LVM is not mounted by default.
Workaround:
Reactivate the volume group to solve the issue, run these command, one by one:
vgchange -a n <volume group name>
vgchange -a y <volume group name>
mount /dev/<volume group name>/<Logical_Volume> <mount_point>
