Package: multipath-tools
Version: 0.4.8+git0.761c66f-9
Transition between 0.4.8-14+lenny2 (Lenny) and 0.4.8+git0.761c66f-9
(Squeeze) cause remove of prio_callout in multipath-tools : that's OK.
But it's replaced by "prio" like the dev says :
* no more prioritizer callouts. replaced by mem-pinned .so to
avoid having to cache the callouts.
* move checkers to mem-pinned .so too
* allow arguments passing to prioritizers

In Squeeze, the two first points are OK. But the last one, arguments,
are not correctly implemented in this version. So, no callout and no
prio_args : there is no possibility to call prio with argument.
The last git version of multipath
(http://kernel.org/pub/scm/linux/storage/multipath-tools/.git) was
compiled and tested : now prio_args works fine !
Let's see an debug from current version of multipath in Squeeze VS the
latest (I introduce a printf for printing if "prio_args "timeout=1000
preferredsds=foo"" in config file were displayed correctly).
Squeeze package :
multipath -ll
ARGS IS sdb
ARGS IS sdc
Obviously, multipath in squeeze takes drive names in arguments, and
NOT prio_args used in the conf.
And now, same conf, same system, but git version of multipath :
multipath -ll
ARGS IS timeout=1000 preferredsds=foo
ARGS IS timeout=1000 preferredsds=foo
And it works !
I am using Debian GNU/Linux squeeze/sid, kernel 22.6.32-5-xen-amd64.
Regards,
Olivier.
