I got a confused issue in docker as below: After install ceph successfully, i want to mount cephfs but failed: [root@dbffa72704e4 ~]$ /bin/mount 172.17.0.4:/<http://172.17.0.4:/> /cephfs -t ceph -o name=admin,secretfile=/etc/ceph/admin.secret -v failed to load ceph kernel module (1) parsing options: rw,name=admin,secretfile=/etc/ceph/admin.secret mount error 5 = Input/output error But ceph related kernel modules have existed: [root@dbffa72704e4 ~]$ lsmod | grep ceph ceph 327687 0 libceph 287066 1 ceph dns_resolver 13140 2 nfsv4,libceph libcrc32c 12644 3 xfs,libceph,dm_persistent_data Check the ceph state(i only set data disk for osd): [root@dbffa72704e4 ~]$ ceph -s cluster: id: 20f51975-303e-446f-903f-04e1feaff7d0 health: HEALTH_WARN Reduced data availability: 128 pgs inactive Degraded data redundancy: 128 pgs unclean services: mon: 2 daemons, quorum dbffa72704e4,5807d12f920e mgr: dbffa72704e4(active), standbys: 5807d12f920e mds: cephfs-1/1/1 up {0=5807d12f920e=up:creating}, 1 up:standby osd: 0 osds: 0 up, 0 in data: pools: 2 pools, 128 pgs objects: 0 objects, 0 bytes usage: 0 kB used, 0 kB / 0 kB avail pgs: 100.000% pgs unknown 128 unknown [root@dbffa72704e4 ~]$ ceph version ceph version 12.2.1 (3e7492b9ada8bdc9a5cd0feafd42fbca27f9c38e) luminous (stable) My container is based on centos:centos7.2.1511, kernel is 3e0728877e22 3.10.0-514.el7.x86_64. I saw some ceph related images on docker hub so that i think above operation is ok, did i miss something important? -- Best Regards Dai Xiang
