Let's review the current situation with regards to files touched by the package : * /etc/multipathd.conf : optional you only need to create one if you use multipath aliases or have hardware not known internaly its synthax is not yet fully stabilized : for example, I may decide to move from multipath { wwid = 00000acdefg123456ff alias = system } to multipath 00000acdefg123456ff { alias = system } also expect a few keyword additions to cover the new reinstate feature of the kernel driver. * /etc/hotplug.d/scsi/multipath dead and to be removed from 0.3.0 and up * /etc/dev.d/block/multipath.dev optional this is where we call multipath and kpartx when nodes appear in /sys/block this one should not change too much, but I expect more feedback from testers * /etc/udev/udev.rules from 0.3.0 and up, we don't touch it anymore * /etc/udev/rules.d/multipath maybe misnamed. I may rename it to device-mapper. this is where I drop the devmap_name rule to alias dm-* devmaps with the devmap name as shown by dmsetup * /etc/mkinitrd/scripts/01_udev /etc/mkinitrd/scripts/02_multipath optional, debian specific, but should be portable to other distribs these copy udev, multipath tools and config files to initrd when mkinitrd is launched. 01_udev also creates a script to fire up udevstart from initrd. udevstart triggers the hotplug chain-reaction that leads to multipaths being created. this certainly needs refining, and I expect distrib packagers to show interest in taking them over. Do you ? hope it clarify things, regards, cvaroqui From mboxrd@z Thu Jan 1 00:00:00 1970 From: christophe.varoqui@free.fr Date: Wed, 06 Oct 2004 10:18:40 +0000 Subject: Re: [dm-devel] [ANNOUNCE] multipath-tools-0.3.0 Message-Id: <1097057920.4163c680eaee0@imp5-q.free.fr> List-Id: References: <1096071849.4466.31.camel@zezette> <1097054573.4163b96d1262c@imp5-q.free.fr> <20041006095009.GD1542@marowsky-bree.de> In-Reply-To: <20041006095009.GD1542@marowsky-bree.de> MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: device-mapper development , Lars Marowsky-Bree Cc: linux-raid@vger.kernel.org, linux-hotplug-devel@lists.sourceforge.net, linux-scsi@vger.kernel.org Selon Lars Marowsky-Bree : > > Upgrade will need you to manualy remove your > > /etc/udev/rules.d/multipath.rules > > and kill your devmap_name rule in udev.rules (we use a separate rules.d > > file now) > > Hi Christophe, do you still plan further configuration file changes in > the immediate future or will the format of the configuration settle down > now? > It all depends on the satisfaction of the testers.
