I have an EBS volume that originally was 1 Tb:

# df -h | grep data
/dev/xvdcl     1000G   54G  946G   6% /usr/share/elasticsearch/data

I then grew it to 3 Tb via the AWS console. Now I want to grow the fs on that volume. First I check the mount point and fs type:

# mount | grep xfs
/dev/xvdcl on /usr/share/elasticsearch/data type xfs (rw,relatime,attr2,inode64,noquota)

But when I run xfs_growfs it tells me it is not actually mounted:

# xfs_growfs -d /usr/share/elasticsearch/data
xfs_growfs: /usr/share/elasticsearch/data is not a mounted XFS filesystem

Could this be because I'm doing it from inside of a docker container running under kubernetes?

Yes, it had something to do with docker. When I logged in to the actual node and ran xfs_growfs it worked as expected.
