Description

Hi there.
Today,I runned a script to do some test on my ceph cluster via a cephfs client,include dd/rm/cp files less than 10K.
After 1 hour,the cephfs client was freezed,So I check my ceph health was below:
[root@MON_137 ceph-deploy]# ceph -s
cluster fe614861-e6fb-426f-90f7-682fd6f2def3
health HEALTH_WARN mds ceph239 is laggy
monmap e3: 3 mons at {MON_137=10.118.202.137:6789/0,MON_156=10.118.202.156:6789/0,MON_9=10.118.202.9:6789/0}, election epoch 130, quorum 0,1,2 MON_9,MON_137,MON_156
