Version 1.4.10
|
|
A
little while back version 1.4.10 was released - the first for some
time. This release fixed a good number of smaller problems that have
been found and is a recommended upgrade for anyone using earlier
versions. The "download [1.4]" link to the left will show a page for
suitable package downloads.
The sources for linuxha.net as a subversion repository are also available at the projects Google code page - click here.

Version 1.4.8
|
|
Although
this web page has not been updated in a little while development of
linuxha.net and it's successor - TrueCL - is continuing. The latest
version of linuxha.net adds supports for raw logical volumes. This is
particularly useful since it also allows a new feature to be fully used
- virtual machine live migration. This allows an application in the
cluster which is a virtual machine to be moved between machines without
having to stop/start the application.

|
|
| Versions 1.2.9 and 1.4.2 Available |
| Again
two releases of Linuxha.net - 1.2.9 using DRBD 0.7.25 to run on Linux
2.4 and 2.6 based kernels, whilst 1.4.2 uses DRBD 8.2.4 to run on Linux
2.6 based kernels only. Both have been through some significant testing
resulting in many small improvements and bug fixes; the release notes
for each contain the necessary details. |

|
| Versions 1.2.7 and 1.4.0 Now Available |
|
| Not
one but two new versions of Linuxha.net have just been posted! 1.2.7 is
a minor bug fix release whilst 1.4.0 offers identical functionality but
is built on DRBD 8.2.1 rather then DRBD 0.7.23. If you wish to upgrade
to the newer version of DRBD you now can! A document describing the
update process from 1.2.x to 1.4.x of Linuxha.net is available on the
resources page. |

|
| Version 1.2.6 Released |
|
| Several
minor improvements and bug fixes have now finally passed necessary
testing and so have been released as version 1.2.6. Users are
encouraged to upgrade after reading the release notes from the
resources page. |

|
| Version 1.2.5 Passes Initial RHEL 5 Testing |
|
| Initial
testing and deployment of Linuxha.net version 1.2.5 has been successful
on RHEL5 and Clones. The full test suite and results will be performed
[and posted] in the next few weeks. |
|

|
|
| Version 1.2.5 Available |
This
minor release includes several minor fixes, but more importantly
removes on of the only restrictions on dynamic application
reconfiguration - the netmask settings can now be changed for an
application even if the application is running.
The latest 0.7.23 of DRBD is also bundled in this release. DRBD version
8.x is not supported as yet, though much of the ground work for support
of this version has also been included in 1.2.5. |
| Posted 28/02/2007 |
|
|
| Version 1.2.4 Available |
Another
release in the 1.2.x series introduces some useful features for
administrators with clustered applications requiring complex IP
configurations, including support for multiple network classes hosts on
the same network cards and more flexible netmask configuration.
A few minor bugs were also found and fixed - see the change log on the development site, or the release notes on the resources page for more details. |

|
| Updated Step-by-Step Guides |
| The
Resources page [link to the left] has tweaked versions of the
step-by-step guides for clustering common applications. Also added at
this time is information on clustering the 'Bind' DNS Server. |
|
Posted 25/10/2006 |
|
|
| Version 1.2.3 Available - and more Application Clustering Guides |
| Version
1.2.3 of Linuxha.net should now be available via the download link to
the left. It features an updated DRBD version and some minor updates.
More importantly more guides to clustering well known applications such
as Mysql, Samba and Apache are also available via the Resources link.
Other applications should hopefully follow shortly. |
|
Posted 07/09/2006 |
|
|
| Oracle 10g Clustering Guide Available |
| Although
Mysql and PostgreSQL may be preferred by many Oracle is a database that
many large organizations rely on. Linuxha.net proves its flexibility by
allowing this database to be configured in a classic fail-over
configuration. For more information see the "Resources" link to the
left. |

|
|
| 1.2.1 Now Available |
|
| This
is a minor update to coincide with the release of the "step-by-step"
guide for 1.2 versions. It includes fixes for two minor bugs and a raft
of manual page updates. |
|
Posted 28/06/2006 |
|
|
| 1.2.0 Now Out! |
|
The
first major upgrade to Linuxha.net since version 1.0.0 was launched is
now considered production ready. This release is an evolution of
the 1.0.x series and offers many benefits, whilst ensuring the
migration from 1.0.x is as painless as possible. Key benefits of 1.2.0
include:
- Improved architecture - more resilient to network failure and more responsive in dealing with them
- Simplified algorithms - several internal algorithms,
including cluster formation, have been simplified - resulting in
improved performance.
- Easier application management - the process of adding or changing applications has been greatly simplified.
- Dynamic IP management - application IP changes can be changed whilst the application is running.
- Reduction in fail-over times
Added to this a migration document describing the upgrade process is available via the 'Resources' link - and this upgrade is on line - no downtime is required. |

| 1.0.11 Released |
|
| Version
1.0.11 is now available. This version contains several bug fixes that
were identified as part of the testing for the up coming 1.2.0 release.
When applicable bug fixes were then back-ported to the 1.0.x series.
Although not major problems were identified the fixes continue to
improve the stability of Linuxha.net. |

|
| 1.0.10 Released & More Resources! |
|
Version
1.0.10 of Linuxha.net has now been released. This is a very minor - but
important - update. It includes the latest version of DRBD to ensure it
works on the very latest kernels. This build has been tested
successfully on Fedora Core 5 for example.
Also
the "Resources" page has been improved with more documentation -
including Fedora Core 5 specific installation notes. More documentation
is due on this page shortly - and some of the older documents will be
updated to reflect the very latest changes as soon as time allows! |

|
| 1.0.8 and 1.1.03 Released |
|
| Versions
1.0.8 and 1.1.03 have been released simultaneously. The changes to each
are almost identical in terms of functionality, if not execution. This
release has several IP fail-over improvements over previous releases.
The 1.1.03 release also introduces a mechanism for checking on lems
daemon functionality and both versions provide more resilience to
problems in Lems modules. The usual release notes can be found here... |
| Posted 11/03/2006 |
|
|
| 1.1.02 Released |
|
The
2nd Beta release of what will become Linuxha.net 1.2.x has been
released. It extends the changes introduced with the first Beta and
improves stability further. One often requested feature has also been
added - support for network throughput statistics, for example:
Network status for slack10s1
Network Status Link Check?
Interface Monitor? R
Kb/S W Kb/S
drbd

|
|
| 1.0.7 Released |
|
| This
releases represents the most stable Linuxha.net release as yet. It
fixes several problems and users are encouraged to upgrade their
clusters when appropriate. Users are invited to read the releases notes first of course... |
| Posted 07/02/2006 |
|
|
| 1.1.01 Released |
|
The
first Beta release of the 1.1 series of Linuxha.net is now available
for download. The pages have been altered to provide suitable links
both both 1.0.x series - known as "production" and "1.1.x" known as
development.
This early Beta still has some rough edges and a conversion document
describing the process of migrating from a 1.0.x cluster to 1.1.x
clusters will appear here in the next few days. |
| Posted 31/01/2006 |
|
| Two new releases soon! |
|
Linuxha.net development is continuing at a good pace. In the next week or so two new releases are expected:
1.0.7 - the stable release - several minor changes, no functionality changes.
1.1.01 - the first of the releases containing significant architecture changes.
1.1.01
attempts to evolve Linuxha.net to ensure it maintains the simplicity of
the solution, whilst improving performance, responsiveness and error
recovery handling. This version involves a separate heart-beat daemon
and many cluster formation and node-failure improvements - and yet the
core cluster daemon contains 10% less code.
Also development on
the code base that will become version 2 is continuing. The
architecture will be very different from 1.x.y releases - though again
the key driver will be to ensure flexibility, performance and features
do not impair simplicity, ease of use and stability. |
