cephfs creation error
Hi all, I just had created a ceph cluster to use cephfs. When i create the a ceph fs pool i get the filesystem below error. # ceph osd pool create cephfs_data 128 pool 'cephfs_data' created # ceph osd pool create cephfs_metadata 128 pool 'cephfs_metadata' created # ceph fs new cephfs cephfs_metadata cephfs_data new fs with metadata pool 6 and data pool 5 # ceph -s cluster: id: 1c27def45-f0f9-494d-sfke-eb4323432fd health: HEALTH_ERR 1 filesystem is offline 1 filesystem is online with fewer MDS than max_mds services: mon: 2 daemons, quorum ceph-mon01,ceph-mon02 mgr: ceph-adm01(active) mds: cephfs-0/0/1 up osd: 12 osds: 12 up, 12 in data: pools: 2 pools, 256 pgs objects: 0 objects, 0 B usage: 12 GiB used, 588 GiB / 600 GiB avail pgs: 256 active+clean but when i check the max_mds for the ceph fs it says 1 # ceph fs get cephfs | grep max_mds max_mds 1 Let anyone know what am i missing here? Any inputs is much appreciated. Regards, Ram Ceph-explorer..

You have no MDS available. Are you not running the daemon? -- Patrick Donnelly, Ph.D. He / Him / His Senior Software Engineer Red Hat Sunnyvale, CA GPG: 19F28A586F808C2402351B93C3301A3E258DD79D
Hi Patrick, Right I missed the daemons. After it’s creation cluster health returned OK. Thanks for your inputs.. Regards, Ram. On Tue, 20 Aug 2019 at 2:13 AM, Patrick Donnelly <pdonnell@redhat.com> wrote:
