Symptoms

During an upgrade, system reboot or restart of the statsd daemon, if a performance graph /var/rrd/*.info file is corrupt, the system is expected to backup the performance data before replacing it and starting with new empty graph data. It is then possible to manually recover the previous performance data. However, if the /shared/rrd.backup directory already exists, the system restarts the performance graph with new data without backing up the previous data.

Impact

The previous performance graph data is not displayed, and is no longer available for manual recovery.

Conditions

During startup of the statsd daemon (such as after an upgrade or reboot), the issue occurs if the following two conditions are present: * The /var/rrd/<filename>.info files are corrupt (CRC value does not match contents). * The /shared/rrd.backup directory exists.

Workaround

Old performance graph data can be extracted from the var/rrd directory of a QKView taken prior to the beginning of the problem.

Fix Information

Corrupt performance graph RRD data is now backed up to the /shared/rrd.backup directory during startup even if the directory already exists.
