Cannot create CephFS without keyring

[tinduong1337]

Hello,

I have running Ceph cluster without cephx and now I would like to create CephFS but encountered this error:

ceph not fully configured - missing '/etc/pve/priv/ceph.client.admin.keyring' (500)

is cephx required for CephFS? if not what is the best approach to create CephFS in this case?
