Ceph

On a single node bobtail cluster,the ceph-auth setting is as mentioned below,

ubuntu@burnupi09:/etc/ceph$ sudo cat ceph.conf
[global]
auth service required = none
auth cluster required = none
auth client required = none

on a client running bobtail version of ceph-fuse, mount fails with the following error message,

ubuntu@burnupi13:~$ sudo ceph-fuse -v
ceph version 0.55.1-294-g0dd1302 (0dd1302543422e2bac65d634ed2f1f4260dcae79)

But, ceph-fuse mount succeeds when the flag "auth-client-required=none" is set

ubuntu@burnupi13:~$ sudo ceph-fuse -m 10.214.134.34:6789 /mnt/test --debug-auth=10 --debug-ms=10 --auth-client-required=none

as the default authentication in bobtail is "auth client required = cephx,none" , I expected it to work without a need for keyring or auth setting on the client. But looks like there has to be a explicit mention of "auth client required" on the client side.

also, please note that am able to successfully do a ceph-fuse mount with argonaut version of ceph-fuse on the same cluster[burnupi09] without any need for ceph.conf or keyring on the client side.

ubuntu@burnupi14:~$ sudo ceph-fuse -v

We may have to either fix this issue or make a note of this in the release notes as this is different from argonaut behaviour.
