1. Linuxga kirish

Tayyor RAIDga disk qo’shish
1.>sudo mdadm - - add /dev/md5 /dev/sdc
>cat /proc/mdstat
>cat /etc/mdadm/mdadm.conf (mdadmni konfiguratsiyalarini ko’rish)
>sudo mdadm - - detail - - scan > /etc/mdadm/mdadm.conf
Rebootdan keyin ishlashi uchun configuratsion filega yozib quyamiz.
>cat /etc/mdadm/mdadm.conf
>reboot now
2.Disklarni qismlarga bo’lib,RAID ga qo’shish.
1.1 ta kattaroq disk qo’shamiz.
>ls /dev/sd* (qo’shilgan diskni ko’ramiz)
>sudo apt install fdisk
>sudo fdisk -l (fdisk orqali disklarning ro’yhatini chiqarish)
1.Partitionning tipini o’zgartirib olishimiz kerak
2.3 ta razdelga bo’lishimiz kerak
3.Formatlarni o’zgartirib chiqishimiz kerak
>sudo fdisk /dev/sdb

13-lesson.Mounting.
1.Mount haqida tushuncha
2.>ls /dev/sd* (Bizdagi bor disklarni chiqaradi)
3.>df -h (Sistemaga mount qilingan disklarni ko’rish)
4.>sudo apt update
>sudo apt install fdisk parted
>sudo fdisk /dev/sdd (hali mount qilinmagan disk)

>ls /sbin/mkfs.* (qanaqa fayl tizimi borligini ko’ramiz)

>ls /dev/sdd*
>sudo mkfs.ext4 /dev/sdd1
>sudo mkfs.vfat /dev/sdd2
>sudo mount | grep ext4 (ext4 formatidagi fayl sistemani ko’rsatadi)
(2 ta diskni formatlab oldik,endi ularni mount qilamiz)

>sudo mkdir /mnt/disk1 /mnt/disk2

>sudo mount /dev/sdd1 /mnt/disk1
>sudo mount /dev/sdd2 /mnt/disk2
(1 ta papkaga 2 ta diskni mount qilib bo’lmaydi)
