Releasing crmsh version 3.0.0

2017-01-31T10:00:00UTC


Hello everyone!

I'm happy to announce the release of crmsh version 3.0.0 today. The
main reason for the major version bump is because I have merged the
sleha-bootstrap project with crmsh, replacing the cluster
init/add/remove commands with the corresponding commands from
sleha-bootstrap.

At the moment, these commands are highly specific to SLE and openSUSE,
unfortunately. I am working on making them as distribution agnostic as
possible, but would appreciate help from users of other distributions
in making them work as well on those platforms as they do on
SLE/openSUSE.

Briefly, the "cluster init" command configures a complete cluster from
scratch, including optional configuration of fencing via SBD, shared
storage using OCFS2, setting up the Hawk web interface etc.

There are some other changes in this release as well, see the
ChangeLog for the complete list of changes:

* https://github.com/ClusterLabs/crmsh/blob/3.0.0/ChangeLog

The source code can be downloaded from Github:

* https://github.com/ClusterLabs/crmsh/releases/tag/3.0.0

This version of crmsh will be available in openSUSE Tumbleweed as soon
as possible, and packages for several popular Linux distributions are
available from the Stable repository at the OBS:

* http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/

Releasing crmsh version 2.3.1

2016-09-02T10:00:00UTC


Hello everyone!

Today I am releasing crmsh version 2.3.1. The only change this time is
to lower the Python version requirement from 2.7 to 2.6. This is so
that crmsh remains compatible with centOS 6, where there is no
standardized Python 2.7 version available. For users of other
distributions where Python 2.7 is available, there are no other
changes in this release and no need to upgrade.

The source code can be downloaded from Github:

* https://github.com/ClusterLabs/crmsh/releases/tag/2.3.1

Packages for several popular Linux distributions can be downloaded
from the Stable repository at the OBS:

* http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/

Archives of the tagged release:

* https://github.com/ClusterLabs/crmsh/archive/2.3.1.tar.gz

Announcing crmsh stable release 2.1.7

2016-09-01T09:00:00UTC


Today I are proud to announce the release of `crmsh` version 2.1.7!
The major new thing in this release is a backports of the events-based
alerts support from the 2.3 branch.

Big thanks to Hideo Yamauchi for his patience and testing of the
alerts backport.

This time, the list of changes is small enough that I can add it right
here:

- high: parse: Backport of event-driven alerts parser (#150)
- high: hb_report: Don't collect logs from journalctl if -M is set (bsc#990025)
- high: hb_report: Skip lines without timestamps in log correctly (bsc#989810)
- high: constants: Add maintenance to set of known attributes (bsc#981659)
- high: utils: Avoid deadlock if DC changes during idle wait (bsc#978480)
- medium: scripts: no-quorum-policy=ignore is deprecated (bsc#981056)
- low: cibconfig: Don't mix up CLI name with XML tag

You can also get the list of changes from the changelog:

* https://github.com/ClusterLabs/crmsh/blob/2.1.7/ChangeLog

Right now, I don't have a set of pre-built rpm packages for Linux
distributions ready, but I am going to make this available soon. This
is in particular for centOS 6.x which still relies on Python 2.6
support which makes running the later releases there more
difficult. These packages will most likely appear as a subrepository
here (more details coming soon):

* http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/

Releasing crmsh version 2.3.0

2016-08-12T10:30:00UTC


Hello everyone!

I am proud to present crmsh version 2.3.0, the latest stable
release. I would recommend all users to upgrade to 2.3.0 if they
can.

For this release, I would like to begin by highlighting the new
contributors to crmsh since 2.2.0 was released in January:

* Marc A. Smith added the new subcommand "configure load push", which
  removes any configuration lines that aren't included in the cib
  provided when pushing.

* Andrei Maruha added an optional name parameter to the "corosync
  add-node" command, and made the add-node command recycle old node
  IDs if possible.

* Kai Kang fixed a build system bug when removing generated docs,
  causing issues with parallel make.

* Daniel Hoffend contributed various fixes improving support for
  building crmsh for Debian and Ubuntu.

* Pedro Salgado fixed a bug in the graph rendering code in crmsh,
  added a tox configuration file to make testing with multiple
  versions of Python easy, and updated the Travis CI configuration to
  use tox.

* Nate Clark fixed a bug in the parser for fencing hierarchies.

I would also like to thank all the other contributors, testers and
users who have helped in making this release as stable and reliable as
possible.

Some of the other major features in 2.3.0 include:

* Support for the new event-based alerts feature in Pacemaker 1.1.15

* Greatly improved timezone handling in crm report and the history
  explorer

* Improvements to the cluster scripts / wizards, as well as new
  wizards for LVM on DRBD, and NFS on LVM and DRBD and VMware/vCenter

* Better support for fencing remote nodes

The source code can be downloaded from Github:

* https://github.com/ClusterLabs/crmsh/releases/tag/2.3.0

Packages for several popular Linux distributions can be downloaded
from the Stable repository at the OBS:

* http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/

crmsh 2.2.0 is released

2016-01-15T15:00:00UTC


In June of last year, I released Release Candidate 3 of crmsh 2.2.0,
and I honestly expected to have the final version ready no more than a
few weeks later. Well, it took around 6 months, but now it is finally
here!

The source code can be downloaded from Github:

* https://github.com/ClusterLabs/crmsh/releases/tag/2.2.0

Packages for several popular Linux distributions can be downloaded
from the Stable repository at the OBS:

* http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/

Archives of the tagged release:

* https://github.com/ClusterLabs/crmsh/archive/2.2.0.tar.gz
* https://github.com/ClusterLabs/crmsh/archive/2.2.0.zip

There are many new features and quite a few bug fixes, but I'll try to
describe some of the major changes below. For the full list of changes
since version 2.1, see the ChangeLog. I am also including the list
of changes since RC3 in the release notes below.

* https://github.com/ClusterLabs/crmsh/blob/2.2.0/ChangeLog

New features introduced in this version:

* Support for many of the new features introduced in Pacemaker
  1.1.14, including improved support for Pacemaker Remote and
  pattern-based fencing topology configurations.

* The cluster scripts have been greatly improved and are now used as
  the wizards backend for hawk. Together with the improvements in the
  cluster scripts, the crmsh template sublevel has been deprecated,
  and all of the templates are now available as cluster scripts. The
  template sublevel will be removed in a future version.

* The history explorer now replaces the combined log and event files
  from hb_report using the commands crm history log and crm history
  events. Additionally, the info summary now highlights transitions
  that contain error logs or other potentially interesting events.

* Improved verification before committing new changes, for example
  crmsh now warns if colocation constraints are applied to group
  children.

* resource start / stop / restart now take multiple resource arguments.

* Added a maintenance sublevel with commands intended to simplify the
  use of maintenance mode.

* Switched to using the python parallax library instead of pssh for
  remote node communication. Parallax is a fork of pssh with
  additional features added specifically for using it as a python
  library rather than a command line tool. Packages for
  python-parallax can be downloaded from the OBS, or it can be
  installed from PyPI.

Announcing crmsh stable release 2.1.4

2015-05-13T15:30:00UTC


Today we are proud to announce the release of `crmsh` version 2.1.4!
2.1.4 is a minor bug fix release with no major issues, so users
already running 2.1.3 are mostly fine. Instead, the main reason
for releasing 2.1.4 is as an excuse to talk about some other things
that are happening with crmsh!

The details for this release are available below.

History Guide
~~~~~~~~~~~~~

Dejan has written a guide to using the crmsh history
command. For those who are unfamiliar with the history explorer or
want to know more about how to use it, this guide is a great
introduction to what it does and how to use it.

History is not a new crmsh feature, but, as we failed to
advertise it and nothing works without proper marketing, it
probably hasn't seen a very wide use. That's surely a pity and we
hope that this gentle history guide is going to help. 

So, if you use crmsh and if you need help troubleshooting
clusters (I surely do!), take a look here:

http://crmsh.github.io/history-guide/

FYI, the comprehensive crmsh help also has a short description of
the feature:

Goes without saying: all commands are described too.

If you don't use crmsh, you'll still find a lot of useful
information in the guide, so don't skip it.

Hawk Presentation
~~~~~~~~~~~~~~~~~

I presented Hawk [1] and the History Explorer interface which
builds upon the crmsh history feature at openSUSE conf in The Hague
earlier this month. The video of that presentation is online here:

2.2.0 Development News
~~~~~~~~~~~~~~~~~~~~~~~

While 2.1.4 is the latest stable release, I am also working on releasing
2.2.0 which will come with a bunch of new features. I'm still working
on some of these and not everything is in the repository yet, so
2.2.0 is probably at least a month or so away still. I was perhaps
a bit optimistic when I tagged RC1 back in October last year. ;)

However, right now I'd like to focus on one thing that is already in
2.2.0 and which is available if you use the development packages from
OBS: command shorthands. This makes crmsh a lot more convenient to use
from the command line. Basically, you can use any unambiguous subset
of a command name to refer to that command, and crmsh will figure out
what you mean. This may sound confusing, so an example will help with
explaining what I mean:

This is one way of showing the current cluster configuration:

........
crm configure show
........

However, now you can shorten this to the following:

........
crm cfg show
........

Other examples of shorthand are `crm rsc stop r1` or `crm st`
for status. And of course, tab completion in bash still works for
the shorthand variants.

The examples used here are not comprehensive. crmsh is pretty clever
at figuring out which command was intended. Download the development
release and try it out!
