Updating Your Cluster to SUSE
Linux Enterprise 11
If you have an existing cluster based on SUSE® Linux Enterprise Server 10 SP2, you
can update your cluster to run with the High Availability Extension on SUSE® Linux
Enterprise Server 11. For migration purposes, all cluster nodes must be offline and the
cluster must be migrated as a whole—mixed SUSE Linux Enterprise Server 10/SUSE
Linux Enterprise Server 11 clusters are not supported.
For convenience, SUSE® Linux Enterprise High Availability Extension includes a
hb2openais.sh
script with which to convert your data while moving from the
Heartbeat to the OpenAIS cluster stack. The script parses the configuration stored in
/etc/ha.d/ha.cf
and generates a new configuration file for the OpenAIS cluster
stack. Furthermore, it adjusts the CIB to match the OpenAIS conventions, converts the
OCFS2 file system and replaces EVMS with cLVM.
To successfully migrate your cluster from SUSE Linux Enterprise Server 10 SP2 to
SUSE Linux Enterprise Server 11, you need to execute the following steps:
1. Preparing your SUSE Linux Enterprise Server 10 SP2 Cluster (page 100)
2. Updating to SUSE Linux Enterprise 11 (page 101)
3. Testing the Conversion (page 102)
4. Converting the Data (page 102)
After the conversion has been successfully completed, you can bring the updated cluster
online again.
