Re: [ceph-users] v14.2.0 Nautilus released

[Frank Yu]

Hi guys，

I have try to setup a cluster with this version, I found the mgr prometheus
metrics has been changed a lot compared with version 13.2.x.
e.g: there is no ceph_mds_* related metrics, or there is some
configurations I missed ?
These metrics are very important for monitoring a cluster used for
productions.

thanks

Martin, my thanks to Croit for making this repository available.
I have been building Ceph from source on Ubuntu Cosmic for the last few
days.
It is much more convenient to use a repo.

Re: [ceph-users] v14.2.0 Nautilus released

[Martin Verges]

Hello,

we strongly believe it would be good for Ceph to have the packaged
directly on the official Debian mirrors, but for everyone out there
having trouble with Ceph on Debian we are glad to help.
If Ceph is not available on Debian, it might affect a lot of other
Software, for example Proxmox.

You can find Ceph Nautilus 14.2.0 for Debian 10 Buster on our public mirror.

$ curl https://mirror.croit.io/keys/release.asc | apt-key add -
$ echo 'deb https://mirror.croit.io/debian-nautilus/ buster main' >>
/etc/apt/sources.list.d/croit-ceph.list

If we can help to get the packages on the official mirrors, please
feel free contact us!

Re: [ceph-users] v14.2.0 Nautilus released

[Ronny Aasen]

with Debian buster frozen, If there are issues with ceph on debian that 
would best be fixed in debian, now is the last chance to get anything 
into buster before the next release.


it is also important to get mimic and luminous packages built for 
Buster. Since you want to avoid a situation where you have to upgrade 
both the OS and ceph at the same time.

There aren't any Debian packages built for this release because we

yet.

Re: [ceph-users] v14.2.0 Nautilus released

[Sean Purdy]

Hi,


Will debian packages be released?  I don't see them in the nautilus repo.  I 
thought that Nautilus was going to be debian-friendly, unlike Mimic.

[ceph-users] v14.2.0 Nautilus released

[Abhishek Lekshmanan]

We're glad to announce the first release of Nautilus v14.2.0 stable
series. There have been a lot of changes across components from the
previous Ceph releases, and we advise everyone to go through the release
and upgrade notes carefully.

The release also saw commits from over 300 contributors and we'd like to
thank everyone from the community for making this release happen. The
next major release of Ceph will be called Octopus. Consider joining
us in the second edition of Cephalocon, at Barcelona this year
https://ceph.com/cephalocon/barcelona-2019/

For a detailed changelog please refer to the official blog entry at
http://ceph.com/releases/v14-2-0-nautilus-released/

Major Changes from Mimic


- *Dashboard*:

  The Ceph Dashboard has gained a lot of new functionality:

  * Support for multiple users / roles
  * SSO (SAMLv2) for user authentication
  * Auditing support
  * New landing page, showing more metrics and health info
  * I18N support
  * REST API documentation with Swagger API

  New Ceph management features include:

  * OSD management (mark as down/out, change OSD settings, recovery profiles)
  * Cluster config settings editor
  * Ceph Pool management (create/modify/delete)
  * ECP management
  * RBD mirroring configuration
  * Embedded Grafana Dashboards (derived from Ceph Metrics)
  * CRUSH map viewer
  * NFS Ganesha management
  * iSCSI target management (via ceph-iscsi)
  * RBD QoS configuration
  * Ceph Manager (ceph-mgr) module management
  * Prometheus alert Management

  Also, the Ceph Dashboard is now split into its own package named
  ``ceph-mgr-dashboard``. You might want to install it separately,
  if your package management software fails to do so when it installs
  ``ceph-mgr``.

- *RADOS*:

  * The number of placement groups (PGs) per pool can now be decreased
at any time, and the cluster can `automatically tune the PG count 
`_
based on cluster utilization or administrator hints.
  * The new :ref:`v2 wire protocol ` brings support for encryption on 
the wire.
  * Physical `storage devices `_ consumed by OSD and Monitor daemons 
are
now tracked by the cluster along with health metrics (i.e.,
SMART), and the cluster can apply a pre-trained prediction model
or a cloud-based prediction service to `warn about expected
HDD or SSD failures `_.
  * The NUMA node for OSD daemons can easily be monitored via the
``ceph osd numa-status`` command, and configured via the
``osd_numa_node`` config option.
  * When BlueStore OSDs are used, space utilization is now broken down
by object data, omap data, and internal metadata, by pool, and by
pre- and post- compression sizes.
  * OSDs more effectively prioritize the most important PGs and
objects when performing recovery and backfill.
  * Progress for long-running background processes--like recovery
after a device failure--is now reported as part of ``ceph
status``.
  * An experimental `Coupled-Layer "Clay" erasure code
`_
plugin has been added that reduces network bandwidth and IO needed
for most recovery operations.

- *RGW*:

  * S3 lifecycle transition for tiering between storage classes.
  * A new web frontend (Beast) has replaced civetweb as the default,
improving overall performance.
  * A new publish/subscribe infrastructure allows RGW to feed events
to serverless frameworks like knative or data pipelies like Kafka.
  * A range of authentication features, including STS federation using
OAuth2 and OpenID::connect and an OPA (Open Policy Agent)
authentication delegation prototype.
  * The new archive zone federation feature enables full preservation
of all objects (including history) in a separate zone.

- *CephFS*:

  * MDS stability has been greatly improved for large caches and
long-running clients with a lot of RAM. Cache trimming and client
capability recall is now throttled to prevent overloading the MDS.
  * CephFS may now be exported via NFS-Ganesha clusters in environments managed
by Rook. Ceph manages the clusters and ensures high-availability and
scalability. An `introductory demo
`_
is available. More automation of this feature is expected to be forthcoming
in future minor releases of Nautilus.
  * The MDS ``mds_standby_for_*``, ``mon_force_standby_active``, and
``mds_standby_replay`` configuration options have been obsoleted. Instead,
the operator :ref:`may now set ` the new
``allow_standby_replay`` flag on the CephFS file system. This setting
causes standbys to become standby-replay for any available rank in the file
system.
  * MDS now supports dropping its cache which concurrently asks clients
to trim their caches. This is done using MDS admin socket ``cache drop``
command.
  * It is now possible to check the progress of an
