The original error you posted was in linking src/apps/admin/pvfs2-mkspace, which uses trove, but contains none of the pvfs2-server -specific code. If you try to alter the makefile you will run into more problems. For example, both pvfs2-mkspace.c and pvfs2-server.c have a function called "main". I suspect that will just be the beginning of the problems.
Does your new function need to happen *during* the processing that occurs inside trove, or do you just need to make sure it happens after some condition has been met and you recognize that inside trove? You also mentioned calling your function from job.c as an option. Instead, could you use the user_ptr parameter to the job function to store information that indicates you need to run your function upon returning to the calling function that resides in pvfs2-server.c?
