Created page with "How to make a partition, label the partition and create a file system type. In /media I created a directory backup fdisk -l -> To see a list of devices. Say the device is ..."

New page

How to make a partition, label the partition and create a file system type.

In /media I created a directory backup
fdisk -l -> To see a list of devices. Say the device is listed as /dev/sdf
Note the size, so for our example: Disk /dev/sdf: 3000.6 GB, 3000592981504 bytes

parted /dev/sdf
print
It should say this:
(parted) print
Error: /dev/sdf: unrecognised disk label
If not, exit and try to select the device again.
(parted) mklabel gpt
(parted) mkpart logical 0TB 3TB
(parted) print
Model: Initio INIC-1610P (scsi)
Disk /dev/sdf: 3001GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number Start End Size File system Name Flags
1 1049kB 3001GB 3001GB xfs logical

(parted)

(parted) quit

Now when you type fdisk -l you should see under /dev/sdf a “/dev/sdf1” line
Now type:
pvcreate /dev/sdf1
pvdisplay -> sanity check
vgcreate nfs_backup_vg /dev/sdf1
vgdisplay -> sanity check
lvcreate -l 100%FREE -n nfs_backup_lv nfs_backup_vg
mkfs.xfs -L nfs_backup /dev/mapper/nfs_backup_vg-nfs_backup_lv
mount -t xfs /dev/mapper/nfs_backup_vg-nfs_backup_lv /media/backup
