Thank you for the reply. This is a feature that we would like to see.
Should I write a cephfs tracker report on this as a possible future
enhancement?

We don't implement the GETFLAGS and SETFLAGS ioctls used for +i.
Adding the ioctls is pretty easy, but then we need somewhere to put
the flags. Currently we don't store a "flags" attribute on inodes,
but maybe we could borrow the high bits of the mode attribute for this
if we wanted to implement
Should chattr +i work with cephfs?
Using ceph v0.91 and a 3.18 kernel on the CephFS client, I tried this:
# mount | grep ceph
172.16.30.10:/ on /cephfs/test01 type ceph (name=cephfs,key=client.cephfs)
# echo 1 > /cephfs/test01/test.1
# ls -l /cephfs/test01/test.1
