Hello, I try to mount a cephfs filesystem from fresh luminous cluster. With the latest kernel 4.13.3, it works > $ sudo mount.ceph iccluster041.iccluster,iccluster042.iccluster,iccluster054.iccluster:/ /mnt -v -o name=container001,secretfile=/tmp/secret > parsing options: name=container001,secretfile=/tmp/secret > $ df -h /mnt > Filesystem Size Used Avail Use% Mounted on > 10.90.38.17,10.90.38.18,10.90.39.5:/ 66T 19G 66T 1% /mnt > root@iccluster054:~# ceph auth get client.container001 > exported keyring for client.container001 > [client.container001] > key = <snip> > caps mds = "allow rw" > caps mon = "allow r" > caps osd = "allow rw pool=cephfs_data" > root@iccluster05:~#:/var/log# ceph --cluster container fs authorize cephfs client.container001 / rw > [client.container001] > key = <snip> With the latest Ubuntu 16.04 LTS Kernel and ceph-common 12.2.0, I'm not able to mount it > Linux iccluster013 4.4.0-96-generic #119~14.04.1-Ubuntu SMP Wed Sep 13 08:40:48 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux > ii ceph-common 12.2.0-1trusty amd64 common utilities to mount and interact with a ceph storage cluster > root@iccluster013:~# mount.ceph iccluster041,iccluster042,iccluster054:/ /mnt -v -o name=container001,secretfile=/tmp/secret > parsing options: name=container001,secretfile=/tmp/secret > mount error 110 = Connection timed out here the dmesg : > [ 417.528621] Key type ceph registered > [ 417.528996] libceph: loaded (mon/osd proto 15/24) > [ 417.540534] FS-Cache: Netfs 'ceph' registered for caching > [ 417.540546] ceph: loaded (mds proto 32) > [...] > [ 2596.609885] libceph: mon1 10.90.38.18:6789 feature set mismatch, my 107b84a842aca < server's 40107b84a842aca, missing 400000000000000 > [ 2596.626797] libceph: mon1 10.90.38.18:6789 missing required protocol features > [ 2606.960704] libceph: mon0 10.90.38.17:6789 feature set mismatch, my 107b84a842aca < server's 40107b84a842aca, missing 400000000000000 > [ 2606.977621] libceph: mon0 10.90.38.17:6789 missing required protocol features > [ 2616.944998] libceph: mon0 10.90.38.17:6789 feature set mismatch, my 107b84a842aca < server's 40107b84a842aca, missing 400000000000000 > [ 2616.961917] libceph: mon0 10.90.38.17:6789 missing required protocol features > [ 2626.961329] libceph: mon0 10.90.38.17:6789 feature set mismatch, my 107b84a842aca < server's 40107b84a842aca, missing 400000000000000 > [ 2626.978290] libceph: mon0 10.90.38.17:6789 missing required protocol features > [ 2636.945765] libceph: mon0 10.90.38.17:6789 feature set mismatch, my 107b84a842aca < server's 40107b84a842aca, missing 400000000000000 > [ 2636.962677] libceph: mon0 10.90.38.17:6789 missing required protocol features > [ 2646.962255] libceph: mon1 10.90.38.18:6789 feature set mismatch, my 107b84a842aca < server's 40107b84a842aca, missing 400000000000000 > [ 2646.979228] libceph: mon1 10.90.38.18:6789 missing required protocol features Is there specific option to set on the cephfs to be able to mount it on a kernel 4.4 ?
