Building an HA Cluster Configuration
Setting up the Quorum Server
Chapter 5152
Installing the Quorum Server
Use the Linux rpm command to install the quorum server, product
number B8467BA, on the system or systems where it will be running.
You do not need to install the product on nodes that are simply using
quorum services. More details on installation are in the Quorum Server
Release Notes for your version of Quorum Server.
The quorum server executable file, qs, is installed in the
/usr/local/qs/bin directory for Red Hat or /opt/qs/bin for SUSE.
When the installation is complete, you need to create an authorization
file on the server where the QS will be running to allow specific host
systems to obtain quorum services. The required pathname for this file is
/usr/local/qs/conf/qs_authfile for Red Hat or
/opt/qs/conf/qs_authfile for SUSE. Add to the file the names of all
cluster nodes that will access cluster services from this quorum server.
Enter one node per line, or enter “+” (followed by a
CR) to allow access by
all nodes. Use one line per node, as in the following example:
ftsys9.localdomain.com
ftsys10.localdomain.com
NOTE The quorum server reads the authorization file at startup. Whenever you
modify the file qs_authfile, run the following command to force a
re-read of the file. For example on a Red Hat distribution:
/usr/local/qs/bin/qs -update
On a SUSE distribution:
/opt/qs/bin/qs -update
