Format And Mount local2

Format Disk

Do these commands as root:

• fdisk -l
  • Find disks/RAID disks to format
• parted
• print
• mklabel gpt
• mkpart logical 0GB 9995GB. (based on what we read in result of print above)
• print. (to confirm)
• quit

Mount storage disks using LVM

Reference guide: https://www.thegeekdiary.com/redhat-centos-a-beginners-guide-to-lvm-logical-volume-manager/

Scan devices to be used as physical volumes (PV)

• lvmdiskscan

Initialize the block devices

• pvcreate <drive1> <drive2> <...> ...
  • Example: pvcreate /dev/sdb /dev/sdc /dev/sdd

To double check PV

• pvdisplay
• pvscan
• pvs

After PV, create a Volume Group (VG)

• vgcreate <name of volume> <drive1> <drive2> <...> ...
  • Example: vgcreate soft2 /dev/sdb /dev/sdc /dev/sdd

To double check VG

• vgs <VG name>
• vgdisplay <VG name>

After VG, create a Logical Volume (LV)

• lvcreate <options> <name of LV> <VG Name>
  • Example: lvcreate -l 100%FREE -n soft_lv soft2
    • -l is for storage space in percent, 100%FREE means use all space in VG
    • -n is for name of LV

Double Check LV

• lvs /dev/<VG NAME>/<LV NAME>
• lvdisplay /dev/<VG NAME>/<LV NAME>
• lvscan

Last step, create a File System

• mkfs.ext4 <options> /dev/<VG NAME>/<LV NAME>
• Example: mkfs.ext4 /dev/soft2/soft_lv

It's time to mount Make the directory first:

• mkdir <somewhere>
  • Example: mkdir /export/soft2
• mount /dev/<VG NAME>/<LV NAME> <somewhere>
  • Example: mount /dev/soft2/soft_lv /export/soft2/

Make it permanent by editing fstab:

• vim /etc/fstab

/dev/<VG NAME>/<LV NAME>      <somewhere>       <type of file system>      <mount options>      <dump>         <fsck>
example:
/dev/soft2/soft_lv	/export/soft2	ext4	defaults	1	2
