It honestly just looks like your MDS and MGR daemons are not configured to start automatically. Try starting them manually and then if that fixes the things, go through and enable them to start automatically. Assuming you use systemctl the commands to check and fix this would be something like these. The first one will show you all of the things started with ceph.target.
sudo systemctl list-dependencies ceph.target
sudo systemctl enable ceph-mgr@servername
sudo systemctl enable ceph-mgr@servername
sudo systemctl enable ceph-mds@servername

Hi all,
hope that somebody can help me. I have home ceph installation.
After power failure (it can happen in datacenter also) my ceph booted in
non-consistent state.
I was backfilling data on one new disk during power failure. First time
it booted without some OSDs, but I fixed that. Now I have all my OSD's
running, but cluster state looks like this after some time. :

There are all OSD's up and running. Before that I completed
ceph osd out
on one of my disk and removed that disk from cluster because I don't
want to use it anymore. It triggered crush reweight and started to
rebuild my date. I thinkg that should not put my data in danger even I
saw that some of my PG's were undersized (why?) - but it is not now the
think.
When I try to do
ceph pg dump
I have no response.
But ceph osd dump show weird number of osd's on temporary PG's like
number 2147483647. I thing that there is some problem in some mon or
other database and peering process cannot complete.
What can I do next? I believed that cluster so much, so I have some data
I want back. Thank you very much. for help.
My ceph osd dump looks like this:
