Subject: [PATCH] RH: don't start without a config file
|
|
|
|
If /etc/multipath.conf doesn't exist, don't start multipathd and blacklist
|
|
all devices when running multipath. A completely blank configuration file
|
|
is almost never what users want. Also, people may have the multipath
|
|
packages installed but don't want to use them. This patch provides a
|
|
simple way to disable multipath. Simply removing or renaming
|
|
/etc/multipath.conf will keep multipath from doing anything.
