I'll defer to others who maintain and develop multipathd but I'll say that I think it'd be more logical/correct to _not_ code multipathd to do this directly. But rather have your own code that interfaces with multipathd to get the multipath info and push it where you'd like. Newer multipathd code that was added to make programmatic access to multipathd state easier/possible includes: 1) multipathd show maps json multipathd show map $map json 2) Use libdmmp (see multipath-tools commit 4335abb36f33f1). libdmmp provides access to the json output via C api. (thanks to Todd and Gris for providing pointers to these interfaces) Mike -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
