Ceph » RADOS

Hi all,
We have 3 nodes ceph cluster, version 10.2.10.
new installing enviroment and prosessional rpms from download.ceph.com.
We had a test found that pg status keep always peering and stucked,
util I restart the pg mapped primary osd.
The restarted osd number is 22 at the node that cables is pulled and put.
I think it maybe a serious bug,due to the status will keeped util no end.
