1. Создаём на диске новый раздел

sudo fdisk /dev/sdb

• Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

• After that, of course, the previous content won't be recoverable.

Changed system type of partition 1 to 8e (Linux LVM)

Hex code (type L to list codes): 8e // код Linux LVM - 8e

Command (m for help): w // записываем изменения на диск

• The partition table has been altered!
• Syncing disks.
• Calling ioctl() to re-read partition table.

Проверяем:

sudo fdisk -l /dev/sdb

• Disk /dev/sdb: 21.5 GB, 21474836480 bytes
• 255 heads, 63 sectors/track, 2610 cylinders
• Units = cylinders of 16065 * 512 = 8225280 bytes
• Sector size (logical/physical): 512 bytes / 512 bytes
• I/O size (minimum/optimal): 512 bytes / 512 bytes
• Disk identifier: 0x217118ba
• Device Boot Start End Blocks Id System
• /dev/sdb1 1 2610 20964793+ 8e Linux LVM

2. Инициализируем раздел

sudo pvcreate /dev/sdb1

Physical volume «/dev/sdb1» successfully created

Проверяем:

sudo pvdisplay

• --- Physical volume ---
• PV Name /dev/sda2
• VG Name vg_mainhome
• PV Size 19.51 GiB / not usable 3.00 MiB
• Allocatable yes (but full)
• PE Size 4.00 MiB
• Total PE 4994
• Free PE 0
• Allocated PE 4994
• PV UUID M6Rqrd-DDVf-0crg-pXCx-tmgX-SylT-T6TGxG
• «/dev/sdb1» is a new physical volume of «19.99 GiB»
• --- NEW Physical volume ---
• PV Name /dev/sdb1
• VG Name
• PV Size 19.99 GiB
• Allocatable NO
• PE Size 0
• Total PE 0
• Free PE 0
• Allocated PE 0
• PV UUID fbmaqp-LK9p-BNLb-65Nb-NMed-baq5-YITjq3

3. Создаём LVM раздел с именем «repository»

sudo vgcreate repository_vg /dev/sdb1

• Volume group «repository» successfully created

Проверяем:

sudo vgdisplay repository_vg

• --- Volume group ---
• VG Name repository
• System ID
• Format lvm2
• Metadata Areas 1
• Metadata Sequence No 1
• VG Access read/write
• VG Status resizable
• MAX LV 0
• Cur LV 0
• Open LV 0
• Max PV 0
• Cur PV 1
• Act PV 1
• VG Size 19.99 GiB
• PE Size 4.00 MiB
• Total PE 5118
• Alloc PE / Size 0 / 0
• Free PE / Size 5118 / 19.99 GiB
• VG UUID ZWuShS-Dc0z-fRQW-Fmv3-1PUz-i4B2-OFf0Yb

4. Создаём логический раздел на этой группе томов (хотя он тут один)

sudo lvcreate --name repository_lv --size 19G repository_vg

• Logical volume «repository» created

Проверяем:

sudo lvdisplay /dev/repository_vg/repository_lv

• --- Logical volume ---
• LV Path /dev/repository/repository
• LV Name repository
• VG Name repository
• LV UUID AwCKQS-kHpY-4dmu-sB1f-7Glm-jCtV-my5tfz
• LV Write Access read/write
• LV Creation host, time cent_1, 2015-01-16 09:53:18 +0200
• LV Status available

• open 0

• LV Size 19.00 GiB
• Current LE 4864
• Segments 1
• Allocation inherit
• Read ahead sectors auto
• • currently set to 256
• Block device 253:2

5. Создаём файловую систему на новом разделе

sudo mkfs.ext4 /dev/repository_vg/repository_lv

• mke2fs 1.41.12 (17-May-2010)
• Filesystem label=
• OS type: Linux
• Block size=4096 (log=2)
• ...
• Writing inode tables: done
• Creating journal (32768 blocks): done
• Writing superblocks and filesystem accounting information: done

Проверяем:

sudo blkid /dev/repository_vg/repository_lv

• /dev/repository/repository: UUID="92103a1a-790a-4732-9b25-e821ecf92dd1" TYPE="ext4"

6. Создаём каталог для монтирования

sudo mkdir /repository

7. Монтируем

sudo mount /dev/repository_vg/repository_lv /repository

Проверяем:

sudo mount

• /dev/mapper/vg_mainhome-lv_root on / type ext4 (rw)
• proc on /proc type proc (rw)
• sysfs on /sys type sysfs (rw)
• devpts on /dev/pts type devpts (rw,gid=5,mode=620)
• tmpfs on /dev/shm type tmpfs (rw)
• /dev/sda1 on /boot type ext4 (rw)
• none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
• /dev/mapper/repository-repository on /repository type ext4 (rw)

sudo ls -l /repository/

• total 16
• drwx------ 2 root root 16384 Jan 16 09:54 lost+found

8. Редактируем /etc/fstab

sudo nano /etc/fstab

Добавляем строку:

/dev/repository_vg/repository_lv /repository                  ext4    defaults        0 0

9. Перезапускаем машину

sudo reboot

После перезагрузки – проверяем:

df -h /repository/

• Filesystem Size Used Avail Use% Mounted on
• /dev/mapper/repository-repository
• 19G 44M 18G 1% /repository

Готово.
