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

You have no MDS available. Are you not running the daemon?

Hi Patrick,
Right I missed the daemons. After it’s creation cluster health returned OK.
Thanks for your inputs..
Regards,
Ram.
