Subject: Re: multipathd: error calling out mpath_prio_hds_modular
Date: Fri, 16 May 2008 14:01:37 -0700 [thread overview]
Message-ID: <20080516210137.GA1286@us.ibm.com> (raw)
In-Reply-To: <ABFD05FF09D13E4883B757E75603624D011E94FF@ex-sea1.vistocorp.com>
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.)
