Accept -q as the short form of --quiet. Suppress non-essential standard output if -q is given twice. Treat log/silent in lvm.conf as equivalent to -qq. Review all log_print messages and change some to log_print_unless_silent. When silent, the following commands still produce output: dumpconfig, lvdisplay, lvmdiskscan, lvs, pvck, pvdisplay, pvs, version, vgcfgrestore -l, vgdisplay, vgs. [Needs checking.] Non-essential messages are shifted from log level 4 to log level 5 for syslog and lvm2_log_fn purposes.

/*
|
|
* printf()-style macros to use for messages:
|
|
*
|
|
* log_error - always print to stderr.
|
|
* log_print - always print to stdout. Use this instead of printf.
|
|
* log_verbose - print to stdout if verbose is set (-v)
|
|
* log_very_verbose - print to stdout if verbose is set twice (-vv)
|
|
* log_debug - print to stdout if verbose is set three times (-vvv)
|
|
*
|
|
* In addition, messages will be logged to file or syslog if they
|
|
* are more serious than the log level specified with the log/debug_level
|
|
* parameter in the configuration file. These messages get the file
|
|
* and line number prepended. 'stack' (without arguments) can be used
|
|
* to log this information at debug level.
|
|
*
|
|
* log_sys_error and log_sys_very_verbose are for errors from system calls
|
|
* e.g. log_sys_error("stat", filename);
|
|
* /dev/fd/7: stat failed: No such file or directory
