Description Amar Tumballi 2012-01-16 19:58:37 EST
Description of problem:

Currently there is no proper way to have debug/* translators in the graph through CLI. Adding such an option would be very helpful to debug issues and for QE.

The options provided by this patchset is for enabling either trace or error-gen translator on the brick vol file.

$ gluster volume set <VOLNAME> trace <translator-name> 

$ gluster volume set <VOLNAME> error-gen <translator-name>

here <translator-name> can be one of 'posix', 'locks', 'io-threads', 'acl', "marker", "index", upon which, the given debug translator is added to the the graph above the given type of translator.

Verified it on 3.3.0qa45 build. It works fine for all the 6 xlators mentioned above.
Currently there is no validation for the command. Accepts any string in place of <translator-name>. Will file a new bug for that.
