try

# rpm -qa | grep xfs

If you see anything with "kmod" you're running an exceptionally old xfs codebase.

2.6.18-138 and beyond should have a newer xfs backport built into the kernel
rpm itself, as shipped from Red Hat.  But the ancient xfs-kmod (or similar)
provided xfs.ko will take precedence even if you update that kernel.

If at all possible I'd try an updated kernel, especially if your xfs.ko
is provided by the very, very, very old centos xfs-kmod rpm.
