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 to do that and output from our Ubuntu terminal.
apt-get install xfsprogs

Steps to Create XFS File System in Ubuntu
3. Now, once you have installed the XFS package following the 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
root@ubuntu:~#
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.
