Chapter 6. High Availability (HA)
6.3.1. Recovering from Minor Failures
If the primary went down because of a minor failure (overheating trouble, faulty processor, faulty
memory etc.) and the contents of the files in /var/lib/vsm are untouched, recovery is very simple and
fully automatic. Simply start the server and let the two VSM servers resynchronize with eachother.
6.3.2. Recovering from Catastrophic Failure
If a catastrophic failure has occured, and no data on the disks of the primary can be recovered, ThinLinc
needs to be reinstalled and HA must be reinitialized.
Install ThinLinc as described in Section 6.2.1, but before starting the VSM server after enabling HA in
the configuration file, copy the file /var/lib/vsm/sessions from the secondary to the primary. That
will preload the database of active sessions with more current values on the primary.
