There are a couple of places where this pattern is used:

        try:
            self.prepare(args)
        except Exception:
            logger.error('lvm prepare was unable to complete')
            logger.info('will rollback OSD ID creation')
            rollback_osd(args, self.osd_id)
            raise

In some cases, an exception can be thrown in rollback_osd, so the original exception is lost. This needs to be logged with `logger.exception`
