Description Guillaume Abrioux 2017-06-02 10:38:44 UTC 
Description of problem:

The check of PGs is not really efficient because the current check might be satisfied as long as 1 PG is active+clean.


How reproducible:

The check occurs when the handler are triggered after any modification has been brought to ceph.conf.


Steps to Reproduce:
1. Deploy a new cluster
2. Make a change 
3. run the installer again so the daemons are restarted (OSD in this case)

Actual results:

When the OSD daemons are restarted, the check will be satisfied as long as the pattern 'active+clean' is found in the ceph status output.

Expected results:

The check is satisfied only if the total number of PGs are in 'active+clean' state.
