4. Backing Up and Restoring the Cluster Database

The Cluster Configuration Tool automatically retains backup copies of the three most recently
used configuration files (besides the currently used configuration file). Retaining the backup
copies is useful if the cluster does not function correctly because of misconfiguration and you
need to return to a previous working configuration.
Each time you save a configuration file, the Cluster Configuration Tool saves backup copies
of the three most recently used configuration files as
/etc/cluster/cluster.conf.bak.2
file
/etc/cluster/cluster.conf.bak.1
/etc/cluster/cluster.conf.bak.2
/etc/cluster/cluster.conf.bak.3
If a cluster member becomes inoperable because of misconfiguration, restore the configuration
file according to the following steps:
1. At the Cluster Configuration Tool tab of the Red Hat Cluster Suite management GUI, click
File => Open.
2. Clicking File => Open causes the system-config-cluster dialog box to be displayed.
3. At the the system-config-cluster dialog box, select a backup file (for example,
/etc/cluster/cluster.conf.bak.1
OK.
4. Increment the configuration version beyond the current working version number as follows:
a. Click Cluster => Edit Cluster Properties.
b. At the Cluster Properties dialog box, change the Config Version value and click OK.
5. Click File => Save As.
6. Clicking File => Save As causes the system-config-cluster dialog box to be displayed.
7. At the the system-config-cluster dialog box, select
OK. (Verify the file selection in the Selection box.)
8. Clicking OK causes an Information dialog box to be displayed. At that dialog box, click OK.
