There are three commands you can use to display properties of LVM physical volumes:
command provides physical volume information in a configurable form, displaying one line per physical volume. The
command provides a great deal of format control, and is useful for scripting. For information on using the
command to customize your output, see Section 5.8, “Customized Reporting for LVM”
pvdisplay command provides a verbose multi-line output for each physical volume. It displays physical properties (size, extents, volume group, and so on) in a fixed format.
The following example shows the output of the
pvdisplay command for a single physical volume.
--- Physical volume ---
PV Name /dev/sdc1
VG Name new_vg
PV Size 17.14 GB / not usable 3.40 MB
PE Size (KByte) 4096
Total PE 4388
Free PE 4375
Allocated PE 13
PV UUID Joqlch-yWSj-kuEn-IdwM-01S9-XO8M-mcpsVe
pvscan command scans all supported LVM block devices in the system for physical volumes.
The following command shows all physical devices found:
PV /dev/sdb2 VG vg0 lvm2 [964.00 MB / 0 free]
PV /dev/sdc1 VG vg0 lvm2 [964.00 MB / 428.00 MB free]
PV /dev/sdc2 lvm2 [964.84 MB]
Total: 3 [2.83 GB] / in use: 2 [1.88 GB] / in no VG: 1 [964.84 MB]
