Your CRUSH rule specifies to select 3 different chassis but your CRUSH
ma defines no chassis.
Add buckets of type chassis or change the rule to select hosts.

log messages while recovering from an outage. The following flags are set
on the cluster
flags nodown,noout,nobackfill,norebalance,norecover,noscrub,nodeep-scrub
How do we get these OSDs back to active state? Or

Hi Ceph Users,

Hi,
I suspect your generated CRUSH rule is incorret because of
osd_crush_cooseleaf_type=2 and by default chassis bucket are not created.
Changing the type of bucket to host (osd_crush_cooseleaf_type=1 which is the
default when using old ceph-deploy or ceph-ansible) for your deployment should
Hello,
I have a bright new cluster with 2 pools, but cluster keeps pgs in inactive
state.
I have 3 OSDs and 1 Mon… all seems ok except I could not have pgs in
clean+active state !
I might miss something obvious but I really don’t know what…. Someone could
help me ?
I tried to seek answers
Dear Ceph Users,
As the number of OSDs increase in our cluster, we reach a point where
pg/osd is lower than recommend value and we want to increase it from 4096
to 8192.
Somebody recommends that this adjustment should be done in multiple stages,
e.g. increase 1024 pg each time. Is this a good

We use https://github.com/cernceph/ceph-scripts ceph-gentle-split script to
slowly increase by 16 pgs at a time until we hit the target.

Hi,
it might be dumb question - our ceph-cluster runs with dedicated client and
cluster network.
I understand it like this : client -network is the network interface from where
the client connections come from (from the mon & osd perspective), regardless
of the source-ip-address.
So as long
Hi,
I'm looking for some details about the limits of the metadata used by Ceph.
I founded some restrictions from XFS :
- Max total keys/values size : 64 kB
- Max key size : 255 bytes
Does Ceph has limits for this metadata ?
Thanks in advance !

upgraded from which version? have you try downgrade ceph-mds to old version?

Hey folks - I'm using Luminous (12.2.10) and I was wondering if there's
anything out of the box I need to change performance wise to get the most out
of OpenStack on Ceph. I'm running Rocky (Deployed with Kolla) and running Ceph
deployed via ceph-deploy.
Any tips / tricks / gotchas are greatly
