Module name: multipath-tools
Branch: RHEL5_FC6
Changes by: bmarzins@sourceware.org 2010-04-24 05:28:07
Modified files:
libmultipath : config.h configure.c
multipath : main.c
Log message:
Changed the fix for 579789. Multipath now checks if multipathd is running and
automatically acts accordingly by default. The -q option overrides this.

Hi Ben,
you have a spelling error in the help message (nor/not).
I like this approach better indeed.

Modified files:
libmultipath : config.h dict.c structs.h
multipathd : main.c
Log message:
fix for bz #574813. There is a new default multipath configuration option,
"log_checker_err", setting this to "once" will cause multipathd to only log the
first path failure message at verbosity 2. Further path failure messages are
logged at verbosity 3.
