Metadata server logs

The metadata server logs contain entries for routine activity and error conditions that are generated by the metadata servers. A separate log is maintained for each metadata server in the cluster. If you access these logs through the master metadata server (either from the SAN File System console or the administrative command-line interface using the catlog –log cluster command), you see a consolidated view of the logs for each metadata server in the cluster, ordered by date and time, providing you with cluster-wide view of activities and events. This consolidated view is called the cluster log. If you access these logs through a subordinate metadata server (from the administrative command-line interface), you only see the logs for that particular metadata server.

Each metadata server log has a maximum size of 250 MB. Once a log file reaches its maximum size, it is renamed with a .old extension (for example, the log.std file is renamed log.std.old). An existing .old file is overwritten when a subsequent .old file of the same name is created. The log.std file is then cleared and used for new messages of the indicated type. In this way, 500 MB of each type of log data is maintained.
