I'm a bit confused. The NameNode is only used by HDFS, and so shouldn't be running at all if you're using CephFS. Nor do I have any idea why you've changed anything in a way that tells the NameNode to bind to the monitor's IP address; none of the instructions that I see can do that, and they certainly shouldn't be. -Greg _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
