Background: I am using lvm snapshots in a backup script. My general scripting philosophy is that automation scripts that do not have errors should not generate output that will cause cron to send an email. I am using Ubuntu 10.04 with lvm2.02.54-1ubuntu4. Even with the --quiet option I get "Logical volume <name> created" on stdout with lvcreate and "Logical volume <name> successfully removed" with lvremove. So... I grabbed the source code and started nosing around. In lv_manip.c, I find that these messages are produced with a call to the function log_print. log_print is a macro (in log.h) for LOG_LINE(_LOG_WARN, args). So it looks like the logging system sees these messages as warnings and is printing them even though verbosity is turned down as far as possible. In addition to --quiet on the command line, I have verbose = 0 in lvm.conf which according to the man page "should produce no output". >From my point of view, lv_manip.c should be calling the log_info macro for these messages and not log_print, thus giving the user control over the output as advertised by the documentation. Disclaimer: I did not dig into the source code far enough to be assured that log_info will generated the proper results, but it certainly appears on the surface to be the right option. I also downloaded the latest source tarball (2.0.2.84) and the situation appears to be the same.
