Thanks John, that did the trick for ceph-fuse. But the kernel mount using 4.9.15 kernel still hangs. I guess I might need newer kernel ? -- Deepak -----Original Message----- From: John Spray [mailto:jspray@xxxxxxxxxx] Sent: Friday, March 31, 2017 1:19 AM To: Deepak Naidu Cc: ceph-users Subject: Re: How to mount different ceph FS using ceph-fuse or kernel cephfs mount Hmm, now that I look, the --client_mds_namespace in jewel only took an integer. So do "ceph fs dump", and use the number after the name of the filesystem you want (e.g. where mine says "Filesystem 'cephfs_a' (1)", I would use --client_mds_namespace=1).
