XFS grow not working

Before running xfs_growfs

Give this one a go:

sudo growpart /dev/xvda 1

As per https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/recognize-expanded-volume-linux.html

You have a 4GB xfs file system on a 4GB partition, so there is no work to do.

To overcome, enlarge the partition with parted then use xfs_growfs to expand the fs. You can use parted rm without losing data.

# umount /data
# parted

(parted) quit

# xfs_growfs /dev/xvda2
# mount /dev/xvda2 /data

Done. No need to update /etc/fstab as the partition numbers are the same.

Before running xfs_growfs, Please do the following step first:

#growpart <devicenametobeextend> 

# growpart /dev/xvda 1
