Montarea volumelor logice in Linux (LVM)

Recommended Posts

Uneori aveti nevoie sa faceti mount la volume facute cu LVM si nu puteti utiliza clasicul mount direct pe device. (sdXX)

Cam asa arata partiitia lvm vazuta la fdisk:


root@debian:~# fdisk -l /dev/sda

Disk /dev/sda: 240.1 GB, 240057409536 bytes
255 heads, 63 sectors/track, 29185 cylinders, total 468862128 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0001f2d1

Device Boot Start End Blocks Id System
/dev/sda1 * 2048 514047 256000 83 Linux
/dev/sda2 514048 468860927 234173440 8e [B]Linux LVM[/B]
root@debian:~#

Contrar asteptarilor, se face extrem de simplu utilizand utilitarul lvdisplay pentru a afisa volumele:


root@debian:~# lvdisplay
--- Logical volume ---
LV Path /dev/vg/root
LV Name root
VG Name vg
LV UUID QzUpJS-161D-2cwR-n0fs-jPRw-wkaS-cZ6SrR
LV Write Access read/write
LV Creation host, time devel02.vm, 2014-11-25 14:40:45 +0000
LV Status available
# open 0
LV Size 214.62 GiB
Current LE 6868
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 252:0

--- Logical volume ---
LV Path /dev/vg/tmp
LV Name tmp
VG Name vg
LV UUID 7QpmhZ-8Fi1-ajzg-8803-2Bl1-qdee-KgyszE
LV Write Access read/write
LV Creation host, time devel02.vm, 2014-11-25 14:41:06 +0000
LV Status available
# open 0
LV Size 1.00 GiB
Current LE 32
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 252:1

--- Logical volume ---
LV Path /dev/vg/swap
LV Name swap
VG Name vg
LV UUID IXmZCW-rC3A-v8da-aLnQ-4jqA-amhq-TqRfhQ
LV Write Access read/write
LV Creation host, time devel02.vm, 2014-11-25 14:41:06 +0000
LV Status available
# open 0
LV Size 7.69 GiB
Current LE 246
Segments 1
Allocation inherit
Read ahead sectors auto
- currently set to 256
Block device 252:2

Volumul care ne intereseaza este 'root' (lv name). Acum putem face mount folosind LV Path de la root + un director temporar


root@debian:~# mkdir x
root@debian:~# mount /dev/vg/root x/
