So I have the following setup:
[ec2-user@ip-172-31-9-177 ~]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 80G 0 disk
├─xvda1 202:1 0 6G 0 part /
└─xvda2 202:2 0 4G 0 part /data
All the tutorials I find say to use xfs_growfs <mountpoint> but that has no effect, nor has the -d option:
[ec2-user@ip-172-31-9-177 ~]$ sudo xfs_growfs -d /
meta-data=/dev/xvda1 isize=256 agcount=4, agsize=393216 blks
= sectsz=512 attr=2, projid32bit=1
= crc=0
data = bsize=4096 blocks=1572864, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=0
log =internal bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
data size unchanged, skipping
I should add that I am using:
[ec2-user@ip-172-31-9-177 ~]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.0 (Maipo)
[ec2-user@ip-172-31-9-177 ~]$ xfs_info -V
xfs_info version 3.2.0-alpha2
[ec2-user@ip-172-31-9-177 ~]$ xfs_growfs -V
xfs_growfs version 3.2.0-alpha2
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
GNU Parted 3.1
Using /dev/xvda

(parted) mkpart

(parted) quit
# xfs_growfs /dev/xvda2
# mount /dev/xvda2 /data
Done. No need to update /etc/fstab as the partition numbers are the same.
