I thought that I had corrected that already and apparently I was wrong. The permissions set on MDS for the user mounting the filesystem needs to be "rw". Mine was set to "r'.
ceph auth caps client.cephfs mon 'allow r' mds 'allow rw' osd 'allow rwx pool=cephfs_metadata,allow rwx pool=cephfs_data'
ceph auth caps client.cephfs mon 'allow r' mds 'allow rw' osd 'allow rwx pool=cephfs_metadata,allow rwx pool=cephfs_data'
Thanks!

Sounds like you've got your cephx permission caps set wrong.
