Attaching a cloud disk, how to format disk if its larger than 2 TiB

Question

I found the device name of the disk by going to :

ECS Console > Block Storage > Disks > (Disk ID specific) More > Modify Atrributes.

The run

fdisk /dev/vdb

To create a new partition. But I do not think it is working for disk bigger than 2 TiB, so what is the procedure for doing the same for those.

Answer 1

using parted you can create a partition larger than 2TB.

Answer 2

You could create the file system directly on the disk, without a partition table:

# mkfs.xfs /dev/vdb

But GPT support was added to fdisk in util-linux in 2012, so this should not be necessary.

Answer 3

As 2TiB exceeds the limits of MBR you must use GPT partition.

Here you can find the list of the tools https://wiki.archlinux.org/index.php/partitioning#Partitioning_tools

You can use:

• gdisk
• parted
• GParted
