Hi All,
# 1 #
I encountered 2 problems, I found that one of newly created ceph pool is full that I do not know the reason.
[root@ceph-adm ceph-cluster]# ceph -s
cluster 6dfd4779-3c75-49f4-bd47-6f4c31df0cb2
health HEALTH_WARN
pool 'pool_cephfs' is full
monmap e1: 3 mons at {ceph-mon1=172.19.7.83:6789/0,ceph-mon2=172.19.7.84:6789/0,ceph-mon3=172.19.7.85:6789/0}
election epoch 4, quorum 0,1,2 ceph-mon1,ceph-mon2,ceph-mon3
fsmap e39: 1/1/0 up {0=ceph-adm=up:active}
osdmap e126: 6 osds: 6 up, 6 in
flags sortbitwise
pgmap v508288: 274 pgs, 11 pools, 20172 kB data, 216 objects

Thus, I try to delete the problem pool ''pool_cephfs'', when I tried to delete the pool, error pop up and warn me that "Error EBUSY: pool 'pool_metadata_cephfs' is in use by CephFS". I search thru the mailing list and internet. I has tried several solution but seem not work for me including
1. ceph mds cluster_down
2. systemctl stop ceph-mds@ceph-adm.service
3. ceph fs rm cephfs --yes-i-really-mean-it
4. ceph osd pool delete pool_metadata_cephfs pool_metadata_cephfs --yes-i-really-really-mean-it
Could anyone has idea about it? thanks for advise!
Kelvin
