Missing physical volume after adding disklabel to the disk
Issue
-
System is using LVM on a disk without a disklabel (Partition Table):
# parted /dev/vdb u s p Error: /dev/vdb: unrecognised disk label Model: Virtio Block Device (virtblk) Disk /dev/vdb: 2097152s Sector size (logical/physical): 512B/512B Partition Table: unknown Disk Flags: # lsblk /dev/vdb NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vdb 252:16 0 1G 0 disk └─vgtest-lvtest 253:2 0 1020M 0 lvm /test
-
After running
parted /dev/vdb mklabel msdos
by mistake, LVM is not listed anymore:# parted /dev/vdb u s p Model: Virtio Block Device (virtblk) Disk /dev/vdb: 2097152s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags # lsblk /dev/vdb NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vdb 252:16 0 1G 0 disk
