Description Vasishta 2018-08-10 15:24:49 UTC 
Created attachment 1475108 [details]
File contains snippet of journald logs of an OSD service with verbose enabled

Description of problem:
When multiple cluster confs are there in ceph directory (/etc/ceph) OSD containers fail to start after service restart

Version-Release number of selected component (if applicable):
ceph-3.1-rhel-7-containers-candidate-64277-20180806190637

How reproducible:
Always (1/1)

Steps to Reproduce:
1. Configure containerized cluster 
2. copy some other clusters conf (or any file with ' fsid ' in the file) file to /etc/ceph
3. Restart OSD

Actual results:
OSD containers fail to restart

Expected results:
OSD containers must be up and running

Additional info:
1) other conf file was included to configure rbd-mirroring
2) We were trying to upgrade from 3.0.z5 to 3.1

It was observed that -
"basename "$(grep -R fsid /etc/ceph/ | grep -oE '^[^.]*')" in [1] is returning cluster name of unexpected cluster (The other one)
