Is it possible to use the same cephx key for all instances of MDS or do they each require their own? Mons require the same keyring so I tried following the same pattern by creating a keyring with "mds.", but the MDS is complaining about not being authorized when it tries to start. Am I missing something or is this not possible for MDS keys? If I create a unique key for each MDS instance it works fine, but it would simplify my scenario if I could use the same key. I'm running on Luminous. The key was generated with this: ceph auth get-or-create-key mds. osd allow * mds allow mon allow profile mds The keyring contents are: [mds.] key = AQD62spZw3zRGhAAkHHVokP3BDf8PEy4+vXGMg== I run the following with that keyring: ceph-mds --foreground --name=mds.mymds -i mymds And I see the error: 2017-09-26 22:55:55.973047 7fb004459200 -1 mds.mds81c2n ERROR: failed to authenticate: (22) Invalid argument Thanks, Travis -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
