Optional: To create a partition, use the GNU parted command :

<code bash>
parted /dev/volume
</code>

<code ->
mklabel gpt
</code>

<code ->
Warning: The existing disk label on /dev/volume will be
destroyed and all data on this disk will be lost. Do you want to
continue?
</code>

<code ->
mkpart primary 0% 100%
</code>

<code ->
unit TB
</code>

<code ->
print
print free
</code>

<code ->
quit
</code>

<code bash>
partprobe /dev/volume
</code>
Ou ''addpart'' / ''delpart'' ?

<code bash>
cat /proc/partitions
</code>

To create an XFS file system, type the following command : 
<code bash>
mkfs.xfs -f /dev/partition
</code>
    
For an ext4 files system, type the following command : 
<code bash>
mkfs.ext4 /dev/partition
</code>

<code bash>
#parted /dev/sdb mklabel gpt mkpart P1 0% 100%
parted /dev/sdb mklabel gpt mkpart primary ext4 0% 100%
</code>

<code bash>
parted /dev/sdb unit s print > sdb-pt.parted
</code>

<code bash>
parted -ms /dev/sdb print > sdb-pt.parted2
</code>

<code - sdb.parted2>

=== Exemple 

<code bash>
parted /dev/sdb mklabel msdos mkpart p xfs 0% 100%
