Hi,
I have two OSD and Mon nodes.
I'm going to add third osd and mon on this cluster but before I want to fix
this error:
```
# ceph -s
cluster 8461e3b5-abda-4471-98c0-913e56aec890
health HEALTH_WARN
64 pgs degraded
64 pgs stuck unclean

64 active+undersized+degraded

```
I have executed this command:
```
# ceph pg ls degraded | tail -n +2 | awk '{print $1}' | xargs -n 1 ceph pg
force_create_pg
```
after which I have:
```
# ceph health
HEALTH_ERR 45 pgs are stuck inactive for more than 300 seconds; 19 pgs
degraded; 45 pgs stuck inactive; 19 pgs stuck unclean; 19 pgs undersized;
recovery 2514/5028 objects degraded (50.000%)
```
If I look the pg detail like explain here
http://docs.ceph.com/docs/infernalis/rados/troubleshooting/troubleshooting-pg/#placement-group-down-peering-failure
I have:
```

I don't understand what it's mean.
Now, I don't know what I need to do to fix it.
Some tips?
Best regards,
Stéphane
