Thank you for your feedback.
We have a failure domain of "node".
The question here is a rather simple one:
when you add to an existing Ceph cluster a new node having disks twice (12TB)
the size of the existing disks (6TB), how do you let Ceph evenly distribute the
data across all disks ?
You m

This is one of many reasons for not using HDDs ;)
One nuance that is easy overlooked is the CRUSH weight of failure domains.
If, say, you have a failure domain of "rack" with size=3 replicated pools and
3x CRUSH racks, if you add the new, larger OSDs to only one rack, you will not

Hi,
I'd like to know cache hit rate in ceph osd. I installed prometheus and
grafana. But there aren't cache hit rate on grafana dashbords...
Does Ceph have a cache hit rate counter? I'd like to know the impact of READ
performance on Ceph cluster.
Regards,

Frank,
The only changes in ceph.conf are just the compression settings, most of
the cluster configuration is in the monitor database thus my ceph.conf is
rather short:

mon_host = [list of mons]

I started with Octopus. It had one very serious flaw that I only fixed
by having Ceph self-upgrade to Pacific. Octopus required perfect health
to alter daemons and often the health problems were themselves issues
with daemons. Pacific can overlook most of those problems, so it's a
lot easier to rep

So now we need to empty these OSDs.
The device class was SSD. I changed it to HDD and moved the OSDs
inside the Crush tree to the other HDD OSDs of the host.

Hello Eugen,
I was wrong. I am sorry.
The PGs are not empty and orphaned.
Most of the PGs are empty but a few are indeed used.
And the pool for these PGs is still there. It is the metadata pool of

successfully.
