Otu esi etinye diski ọhụrụ site na iji LVM na sistemụ Linux dị adị

kewara ma ọ bụ ekewa.

Ụfọdụ n'ime okwu ndị ịchọrọ ịghọta mgbe ị na-eji LVM:

  • Mpịakọta anụ ahụ (PV): Ihe mejupụtara diski Raw ma ọ bụ arrays RAID ma ọ bụ ngwaọrụ nchekwa ndị ọzọ.
  • Otu olu (VG): Na-ejikọta mpịakọta anụ ahụ n'ime otu nchekwa.
  • Logical Volume (LV): E kewara VG ka ọ bụrụ nke LV ma tinye ya dị ka nkebi.

N'isiokwu a, anyị ga-ewere gị site na usoro iji hazie diski site na iji LVM na igwe Linux dị ugbu a site na ịmepụta PV, VG's na LV's.

Mara: Ọ bụrụ na ịmeghị ihe ị ga-eji LVM, ịnwere ike itinye diski ozugbo na sistemụ Linux dị ugbu a site na iji ntuziaka ndị a.

  1. Etu esi etinye diski ọhụrụ na sistemụ Linux
  2. Etu esi etinye diski ọhụrụ buru ibu karịa 2TB na sistemụ Linux

Ka anyị tụlee ọnọdụ ebe enwere 2 HDD nke 20GB na 10GB, mana anyị kwesịrị ịgbakwunye naanị akụkụ abụọ otu n'ime 12GB yana 13GB ọzọ. Anyị nwere ike nweta nke a site na iji usoro LVM naanị.

Ozugbo agbakwunyere diski ahụ, ịnwere ike depụta ha site na iji iwu na-esonụ.

# fdisk -l

1. Ugbu a partitions ma diski /dev/xvdcna /dev/xvdd iji fdisk iwu dị ka egosiri.

# fdisk /dev/xvdc
# fdisk /dev/xvdd

Jiri n mepụta nkebi ma chekwaa mgbanwe ndị ahụ site na iji iwu w.

2. Mgbe nkewa gasịrị, jiri iwu na-esonụ iji nyochaa nkebi.

# fdisk -l

3. Mepụta ụda anụ ahụ (PV).

# pvcreate /dev/xvdc1
# pvcreate /dev/xvdd1

4. Mepụta otu olu (VG).

# vgcreate testvg /dev/xvdc1 /dev/xvdd1

Ebe a, \tesvg bụ aha VG.

5. Ugbu a jiri \vgdisplay depụta nkọwa niile gbasara VG dị na sistemụ.

# vgdisplay
OR
# vgdisplay testvg

6. Mepụta mpịakọta ezi uche (LV).

# lvcreate -n lv_data1 --size 12G testvg
# lvcreate -n lv_data2 --size 14G testvg

Ebe a, \lv_data1 na \lv_data2 bụ aha LV.

7. Ugbu a jiri \lvdisplay depụta nkọwa niile gbasara mpịakọta ezi uche dị na sistemụ.

# lvdisplay
OR
# lvdisplay testvg

8. Hazie mpịakọta Logical (LV's) ka ọ bụrụ ext4.

# mkfs.ext4 /dev/testvg/lv_data1
# mkfs.ext4/dev/testvg/lv_data2

9. N'ikpeazụ, bulie faịlụ usoro.

# mount /dev/testvg/lv_data1 /data1
# mount /dev/testvg/lv_data2 /data2

Gbaa mbọ hụ na ịmepụta data1 na data2 akwụkwọ ndekọ aha tupu ị wụnye sistemụ faịlụ.

Ọ bụ ya! N'isiokwu a, anyị tụlere otu esi emepụta nkebi site na iji LVM. Ọ bụrụ na ị nwere ajụjụ ọ bụla ma ọ bụ ajụjụ gbasara nke a, nweere onwe gị biputere na nkwupụta.
