Default multipathd: error calling out mpath_prio_hds_modular

The multipathd tried calling mpath_prio_hds_modular program but it could
not find it! There is a bug in some version of RHEL where multipath has
"mpath_prio_hds_modular" instead of "/sbin/mpath_prio_hds_modular".
Update your multipath tools package or fix it in your
/etc/multipath.conf (this requires some careful modifications!)

--Malahal.
PS: since execv looks for your executable file in the 'cwd', you can
probably make it work by just copying /sbin/mpath_prio_hds_modular to
/mpath_prio_hds_modular (I am assuming that multipathd daemon makes "/"
as it ***home*** before calling this.)

Default multipathd: error calling out mpath_prio_hds_modular

I put a symlink in /
ln -s /sbin/mpath_prio_hds_modular mpath_prio_hds_modular

But it still has the error.

Where would I edit my /etc/multipath.conf to set this?

Thanks!
Craig

The symlink didn't work, but coping the file to / worked.

YES!!!

Thank You!

That is very odd! symlink or hardlink or a real copy of the program
should not make any difference as far as the execv() goes.
