CVSROOT: /cvs/dm
Module name: multipath-tools
Branch: RHEL4_FC5
Changes by: bmarzins at sourceware.org 2008-04-14 22:32:04
Modified files:
. : multipath.conf.annotated
multipath.conf.synthetic
kpartx : devmapper.c devmapper.h kpartx.c
libmultipath : config.c config.h devmapper.c devmapper.h
dict.c propsel.c propsel.h structs.h
multipath : main.c
Log message:
Fix for bz #251388. Added three new parameters to /etc/multipath.conf:
mode, uid, and gid. These can be used to override the default values when
multipath device nodes are created. Unfortunately, you cannot do name
resolution with static binaries, since you must load libnss dynamically, so
uid and gid must use the numerical user id and group id.
