Installing XFS & Creating XFS File System on Ubuntu

XFS file system gives its user many advantages and is becoming one of the preferred file systems. It is now also the default file system in RHEL 7. We have got many requests to make a tutorial on creating XFS filesystem on Ubuntu as by default XFS package is not present in Ubuntu.

In this tutorial, we will learn how to install the XFS package in Ubuntu, create xfs filesystem and then mount it.


Installing XFS and Creating XFS File System on Ubuntu


It is good to know that XFS is fully supported by all Ubuntu versions, though its package is not installed by default and we will have to install the package first. Read about advantage and disadvantage of XFS filesystem at Ubuntu wiki page.


Steps to Install XFS Package in Ubuntu


1. Verify if the “xfsprogs package” is installed or not on your server. Also, if the package is not installed on the server, you will not find “mkfs.xfs” command.

apt list --installed | grep -i xfs


2. Now, install the xfsprogs package if not present. Below is the command and output from our Ubuntu terminal.

apt-get install xfsprogs
root@ubuntu:~# apt-get install xfsprogs

Steps to Create XFS File System in Ubuntu


3. Now, once you have installed the XFS package following above steps, now it is time to create your XFS file system. Take the block device and format it using “mkfs.xfs” command as given below.

root@ubuntu:~# mkfs.xfs /dev/sdb
meta-data=/dev/sdb               isize=512    agcount=4, agsize=32768 blks
         =                       sectsz=512   attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=0
data     =                       bsize=4096   blocks=131072, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0 ftype=1
log      =internal log           bsize=4096   blocks=855, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

If you don’t have extra space on your server, please add additional disk and scan it on the server without rebooting it.


4. Now, once your block device is formatted as XFS, you can mount it using “mount” command.

root@ubuntu:~# mount /dev/sdb /mnt
root@ubuntu:~# df -hP /mnt
Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb        509M   27M  483M   6% /mnt

In the above example, we have mounted the file system temporarily, to mount it permanently put its entry in /etc/fstab file.


This is how simply you can install the XFS package and create your XFS filesystem.
