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. :
cluster:
id: 2d9bf17f-3d50-4a59-8359-abc8328fe801

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:
