I've run through many upgrades without anyone noticing, including in
very busy openstack environments.
As a rule of thumb you should upgrade MONs, OSDs, MDSs and RadosGWs in
that order, however you should always read the upgrade instructions on
the release notes page

Hi ,
We are validating kraken 11.2.0 with bluestore on 5 node cluster with EC
4+1.
When an OSD is down , the peering is not happening and ceph health status
moved to ERR state after few mins. This was working in previous development
releases. Any additional configuration required in v11.2.0

Probably, but still, it's not a requirement. All I'm
Hi,
Is the current strange DNS issue with docs.ceph.com related to this also? I
noticed that docs.ceph.com is getting a different A record from
ns4.redhat.com vs ns{1..3}.redhat.com

I don't know exactly where but I'm guessing in the database of the
monitor server which should be located at
"/var/lib/ceph/mon/".

This is the first release of the Kraken series. It is suitable for
use in production deployments and will be maintained until the next
stable release, Luminous, is completed in the Spring of 2017.

Hello ceph users,
My graphs of several counters in our Ceph cluster are showing abnormal
behaviour after changing the pg_num and pgp_num respectively.
We're using "http://eu.ceph.com/debian-hammer/ jessie/main".
Is this a bug, or will the counters stabilize at some time in the near
future? Or,
Only in that we changed the zone and apparently it hasn't propagated properly.
I'll check with RHIT.

This email is better suited for the 'ceph-users' list (CC'ed).

Here's a really good write up on how to cluster NFS servers backed by RBD
volumes. It could be adapted to use CephFS with relative ease.

What counters exactly? Like pg information? It could be that it needs a scrub
What does `ceph -s` say?

CephFS does not require a central NFS server. Any Linux server can mount the
CephFS volume at the same time. There is also a windows client for CephFS
(https://drupal.star.bnl.gov/STAR/blog/mpoat/cephfs-client-windows-based-dokan-060).
I don't see the need for the NFS/SMB server or complicate
I'm pretty sure the default configs won't let an EC PG go active with
only "k" OSDs in its PG; it needs at least k+1 (or possibly more? Not
certain). Running an "n+1" EC config is just not a good idea.
For testing you could probably adjust this with the equivalent of
min_size for EC pools, but I do
This is resolved. Apparently ns3 was shutdown a while ago and ns4 just

ceph.com, download.ceph.com, and docs.ceph.com all have updated DNS records.

I think he needs the “gateway” servers because he wishes to expose the storage
to clients which won’t speak Ceph natively. I’m not sure I would entirely trust
that windows port of CephFS and there are also security concerns with allowing
end users to talk directly to Ceph. There’s also future st
