Tiny Deathstars of Foulness

You can gather information manually about an Xsan volume using the cvgather command. This occurs per filesystem. For example, to run on a volume named krypted, use the following command:

cvgather -f krypted -o /temp/krypted.debug

You can also enable the debug log to get much more detailed information about each transaction to/from the volume and metadata controllers. To enable the debug log, use the cvdb command.

The -g option will show the state of the debugger. The -e option will enable debugging and -d disables. So, to see the status of the debugger:

cvdb -g

To enable debugging:

cvdb -e

To disable debugging:

cvdb -d

To drop files into syslog:

cvdb -s syslog=debug
