Description

I successfully deployed Ceph cluster with 16 OSDs and created CephFS before.
But after crash due to mds slow request, when creating CephFS, Ceph mds goes creating status and never changes.
Seeing Ceph status, there is no other problem I think. Here is 'ceph -s' result:

csl@hpc1:~/iodc$ ceph -s
cluster:
id: 1a32c483-cb2e-4ab3-ac60-02966a8fd327
health: HEALTH_OK

services:
    mon: 1 daemons, quorum hpc1
    mgr: hpc1(active)
    mds: cephfs-1/1/1 up  {0=hpc1=up:creating}
    osd: 16 osds: 16 up, 16 in
data:
    pools:   2 pools, 640 pgs
    objects: 7 objects, 124B
    usage:   34.3GiB used, 116TiB / 116TiB avail
    pgs:     640 active+clean

However, CephFS still works in case of 8 OSDs.

Is there any doubt of this phenomenon, please let me know. Thank you.

PS. I attached my ceph.conf contents:
