Hmm, SELinux appears to use the "security.selinux" xattr namespace,
and "security.*" is allowed through Ceph's filters. Can you check and
make sure that it's in fact using the xattr labeling scheme and not
something else? Maybe strace the process and check exactly which
syscall fails in what way.

I would expect this to work fine as CephFS enables xattrs by default,

perhaps we've made a mistake in filtering somewhere…

Hello,
I have mounted a cephfs filesystem on Fedora18 client. I am using

The filesystem cannot be labelled to allow it to work with SELinux.
