Rebootless kernels

The next generation ASL Kernel based on the 4.4 branch is now available for Centos/RHEL 7 platforms in tortix-kernel and tortix-kernel-xen channels. A full list of capabilities added to this new generation will be coming up in another post, however the one I wanted to bring to everyones attention first is the ability to support rebootless updates. Also known as "ksplice", rebootless updates will allow you to update a running linux kernel without having any downtime. This is an exciting new capability for Atomicorp and will help to serve everyone by increasing overall uptimes.


Available for EL6 and EL7
In addition to supporting Centos/RHEL 7, we also have beta support for the 4.4 kernel available for Centos/RHEL 6 systems in the [tortix-kernel-testing] and [tortix-kernel-xen] channels that we are actively seeking testers for. If you are interested in testing the 4.4 branch on EL6 platforms, we support parallel installs with the newly named "kernel-asl" package on EL6. You can install kernel-asl on EL6 with:

yum --enablerepo=tortix-kernel-testing install kernel-asl

or for xen platforms (Rackspace, Amazon, etc):

yum --enablerepo=tortix-kernel-xen-testing

Release notes for 3rd party kmods on Centos/RHEL 6 platforms

As the 4.4 branch requires a much newer compiler to support builds, EL6 systems using 3rd party Kernel modules can use the Scientific Linux DevTools repository compiler yum repository:
Code:
[slc6-devtoolset]
name=Scientific Linux CERN 6 (SLC6) - Devtoolset addons
baseurl=http://linuxsoft.cern.ch/cern/devtoolset/slc6X/x86_64/yum/devtoolset/
enabled=1


This is an SCL packaged distribution of gcc and support utilities that installs a parallel version of GCC.
