Hi Ernesto,
Do you have any kind of support matrix you want to achieve? O what are the
test you want to run?
Cheers!

Hi Cephers,
This is to sound out potential interest in supporting VMWare's Photon OS
distribution with Ceph/Cephadm. Photon OS is a lightweight distribution
that is optimized for deploying containers within virtual machines. It is
based on systemd, includes Docker, and uses the tdnf (Tiny DNF) pac
What's the CPU and RAM usage look like for the OSDs? CPU has often
been our bottleneck, with the main thread hitting 100%.

Hi Istvan,
I would like to add a few notes to what Burkhard mentioned already.
First, CephFS has a built-in feature that allows restricting access to
a certain directory:
ceph fs authorize cephfs client.public-only /public rw
This creates a key with the following caps:
caps mds = "allow rw pat
Hello everyone,
We've been experiencing on our quincy CephFS clusters (one 17.2.6 and

(Ceph 17.2.7 and version 4 Linux kernels on all clients) that seem to
originate from slow ops on osds despite the underlying hardware being

Hi Thorn,
so the problem is apparently bound to huge file sizes. I presume they're
split into multiple chunks at ceph side hence producing millions of objects.
And possibly something is wrong with this mapping.
If this pool has no write load at the moment you might want to run the

I was just looking at our crush rules as we need to change them from
failure domain host to failure domain datacenter. The replicated ones
seem trivial but what about this one for EC 4+2?

Hi,
Thanks Stefan.
Yes I do have separate port-channel interfaces, for public and cluster
networks.
I just didn't understand the documentation (which is sometimes not that
clear). For me when you put forward the --cluster_network option, it meant
that --mon-ip was in the public network by default

If you are using CephFS on Pacific v16.2.14(+), the MDS config
`defer_client_eviction_on_laggy_osds' is enabled by default. This
config is used to not evict cephfs clients if OSDs are laggy[1].
However, this can result in a single client holding up the MDS in
servicing other clients. To avoid this,
