What does "Error: /dev/mapper/lubuntu--vg-home: unrecognised disk label" mean for LV home? What can I do about it? Thanks.

  • The error showed up in the output of sudo parted -l, before I created a filesystem on LV home by lvcreate. The contents of /etc/fstab was the default content of Lubuntu, before I created a filesystem on LV /home by lvcreate and added a mount point for the LV. – Tim Feb 23 at 21:24
