Recently we have noticed some issue with one of our filesystem having issue and realized wrong flags on partition which was used as a Physical Volume (PV) in LVM (Logical Volume Management). You must properly set the lvm flag using any tool like fdisk or parted.

Open parted tool

[[email protected] ~]# parted
GNU Parted 3.1
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted

Check the partitions and free space. We can see /dev/sda is already selected; otherwise you use the correct disk.

(parted) print free
Model: DELL PERC H730P Adp (scsi)
Disk /dev/sda: 600GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
32.3kB 1049kB 1016kB Free Space
1 1049kB 1075MB 1074MB primary xfs boot
2 1075MB 71.4GB 70.3GB primary lvm
3 71.4GB 109GB 37.6GB primary lvm
4 109GB 600GB 491GB extended
5 109GB 136GB 26.8GB logical lvm
6 136GB 137GB 1078MB logical lvm
137GB 600GB 463GB Free Space

Create a partition with xfs format.

(parted) mkpart logical xfs 137GB 317G

Check current partions; you can see the partition 7 with 180GB size which we have created just now.
