How to install ocfs2 on redhat fedora11/15/2022 ![]() ![]() If you're running a cluster of openSUSE 13.1 VMs on an openSUSE 12.3 KVM host, multicast may stop working after a while, which will break your cluster. If you're not using a clustered filesystem or DLM, it's probably viable to put the cluster into maintenance mode, shut down the cluster, and upgrade each node in turn, but note that as of this has not been tested for upgrades from openSUSE 12.x to Factory. If you are using anything that requires DLM, or are using a clustered filesystem such as OCFS2, you will have to take the entire cluster offline for the duration of the upgrade. This means a bunch of stuff changes (corosync config, some protocol changes) which breaks online rolling upgrade. ![]() In openSUSE 13.x we moved from corosync 1.4.x to corosync 2.x, and from the v0 pacemaker plugin to the pacemaker MCP. Moving from openSUSE 12.x to 13.x/Leap/Tumbleweed The packages in openSUSE:Tumbleweed are tested by openQA and generally work well, but they are development versions so relying on them for production use is not recommended. For stable versions of the HA packages, see the packages available for openSUSE:Leap. The packages in network:ha-clustering:Stable are largely out of date and should not be relied on, and are mostly used to provide stable builds of crmsh for other distributions like Fedora. New development will generally occur in network:ha-clustering:Factory, with periodic submissions to openSUSE:Tumbleweed. All of this software is included in the base openSUSE distribution, but we also have repositories on OBS to provide newer versions of these packages for various distros.ĭevelopment of these packages occurs in the network:ha-clustering:Factory repository on the Open Build Service. OpenSUSE includes a suite of high availability clustering software, notably Corosync, Pacemaker, DRBD, OCFS2 and various related management tools.
