Metadata server tracing

This topic describes how to enable tracing for metadata servers.

You can enable tracing for the metadata server through the administrative command-line interface using the trace command. This command enables you to control:
  • When tracing begins and ends.
  • The components within the metadata server for which tracing will occur.
  • The level of detail (verbosity) to show during tracing.
Tracing generates a trace log called log.trace, that is stored in /usr/tank/server/log. Like other log files, this file has a maximum file size of 250 MB. When it reaches this size, the SAN File System creates a copy called log.trace.old and clears log.trace. If log.trace.old already exists, it is overwritten.
Note: A minimum level of tracing always occurs for the metadata server, so this file always exists.
