[Storage Disk] Use parted and xfs_growfs to resize XFS disk partition size

Posted on Edited on In , , , Views: Word count in article: 4.3k Reading time ≈ 4 mins.

Resize XFS disk partition size

XFS is a high-performance journaling file system created by Silicon Graphics, Inc. XFS is particularly proficient at parallel IO due to its allocation group based design. This enables extreme scalability of IO threads, filesystem bandwidth, file and filesystem size when spanning multiple storage devices.

GNU Parted is a program for creating and manipulating partition tables.

This article describe how to use parted and xfs_growfs to resize XFS disk partition size dynamically.

Prerequites

Before resizing the disk partition or file system, please backup the data on that disk.

Run

There are two options to resize disk partition.

Option1. Run parted with disk partition

Use lsblk to check disk partition.

$ lsblk
NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda      8:0    0   1T  0 disk
└─sda1   8:1    0  10G  0 part /

Use parted to resize /dev/sda1 disk partition to 300 GB.

# parted /dev/sda resizepart 1
Warning: Partition /dev/sda1 is being used. Are you sure you want to continue?
Yes/No? Yes
End?  [10.7GB]? 300000
Information: You may need to update /etc/fstab.

Use xfs_growfs to growth filesystem on /dev/sda1.
