About Kaspersky Security Center Linux failover cluster

A Kaspersky Security Center Linux failover cluster provides high availability of Kaspersky Security Center Linux and minimizes downtime of Administration Server in case of a failure. The failover cluster is based on two identical instances of Kaspersky Security Center Linux installed on two computers. One of the instances works as an active node and the other one is a passive node. The active node manages protection of the client devices, while the passive one is prepared to take all of the functions of the active node in case the active node fails. When a failure occurs, the passive node becomes active and the active node becomes passive.

In a Kaspersky Security Center Linux failover cluster, all Kaspersky Security Center Linux services are managed automatically. Do not try to restart the services manually.

Use the syslog feature for troubleshooting.

Switch conditions

The failover cluster switches protection management of the client devices from the active node to the passive one, if any of the following events occurs on the active node:

• The active node is broken due to a software or hardware failure.
• The active node was temporarily stopped for maintenance activities.
• At least one of the Kaspersky Security Center Linux services (or processes) failed or incidentally terminated. The Kaspersky Security Center Linux services are the following ones: klnagent_klfoc, kladminserver_klfoc, klactprx_klfoc, klwebsrv_klfoc.
• The network connection between the active node and the storage on the file server was interrupted or terminated.
