All you have to do is figure out why osd.0, osd.1, and osd.2 are down and get the daemons running. They have PGs assigned to them, but since they are not up and running those PGs are in a down state. You can check the logs for them in /var/log/ceph/. Did you have any errors when deploying these OSDs?

Hi List
I've just begun using ceph and installed a small cluster on ubuntu
16.04 nodes using this the process in this guide:
https://www.howtoforge.com/tutorial/how-to-install-a-ceph-cluster-on-ubuntu-16-04/
However, once the installation is complete, I see the newly installed
cluster is not healthy, and complaining about pgs stuck in inactive:

Why is this, and how can troubleshoot and I fix it? (I've googled
extensively but couldn't find a solution to this).
My osd tree looks like this:
----
ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY
-1 10.46080 root default
-2 2.98880 host anx-dp02-046
0 1.49440 osd.0 down 0 1.00000
4 1.49440 osd.4 up 1.00000 1.00000
-3 2.98880 host anx-dp02-047
1 1.49440 osd.1 down 0 1.00000
5 1.49440 osd.5 up 1.00000 1.00000
-4 2.98880 host anx-dp02-048
2 1.49440 osd.2 down 0 1.00000
6 1.49440 osd.6 up 1.00000 1.00000
-5 1.49440 host anx-dp02-049
7 1.49440 osd.7 up 1.00000 1.00000

Many thanks in advance,
