Synchronizing cluster files

The files available on the configuration coordinator are called cluster files. These files are automatically synchronized on the other cluster nodes when the node is added to the cluster and periodically, during the lifetime of the cluster. Also, you can manually synchronize the cluster files.

Important: Removing any certificate or key files in a cluster environment restricts further configuration on the ADC appliance. Add the files back at the same location to make any configuration changes.

The directories and files from the configuration coordinator that are synchronized are:

  • /nsconfig/ssl/
  • /var/netscaler/ssl/
  • /var/vpn/bookmark/
  • /nsconfig/dns/
  • /nsconfig/htmlinjection/
  • /netscaler/htmlinjection/ens/
  • /nsconfig/monitors/
  • /nsconfig/nstemplates/
  • /nsconfig/ssh/
  • /nsconfig/rc.netscaler
  • /nsconfig/resolv.conf
  • /nsconfig/inetd.conf
  • /nsconfig/syslog.conf
  • /nsconfig/snmpd.conf
  • /nsconfig/ntp.conf
  • /nsconfig/httpd.conf
  • /nsconfig/sshd_config
  • /nsconfig/hosts
  • /nsconfig/enckey
  • /var/nslw.bin/etc/krb5.conf
  • /var/nslw.bin/etc/krb5.keytab
  • /var/lib/likewise/db/
  • /var/download/
  • /var/wi/tomcat/webapps/
  • /var/wi/tomcat/conf/Catalina/localhost/
  • /var/wi/java_home/lib/security/cacerts
  • /var/wi/java_home/jre/lib/security/cacerts
  • /nsconfig/license/
  • /nsconfig/rc.conf


Files (certificates and key files) that are copied to the cluster configuration coordinator manually (or through the shell) are not automatically available on the other cluster nodes. Run the “sync cluster files” command from the cluster IP address before running a command that depends on these files.

To synchronize cluster files by using the command line interface

At the command prompt of the cluster IP address, type:

sync cluster files <mode>

To synchronize cluster files by using the configuration utility

  1. Log on to the cluster IP address.
  2. Navigate to System > Cluster.
  3. In the details pane, under Utilities, click Synchronize cluster files.
  4. In the Synchronize cluster files dialog box, select the files to be synchronized in the Mode drop-down list.
  5. Click OK.
