Is anyone taking a look at porting the multipathd legacy sysv init
script to native systemd unit file?
I filed 690828 on 2011-03-25 and yet to receive somekind of response on
it and unless some action is taken then a) device-mapper-multipath will
be blocking the Fedora 16 alpha release or b) be ripped out of @base and
be made sure it does not get installed on the official livecd.
So please take a look at this..
Thanks
JBG

You will need to cc me to your responses since I'm not subscripted

The main problem here is that we don't / can't know if a device is multipathed or not; this is basically a policy decision. Even a simple switch (multipath on/off) wouldn't suffice here, as this particular device might be excluded via the configuration file. Idea here is to modify the 'multipath' program to determine if a particular device is handled by multipath or not. If so, _no other_ configuration must be done in that device. The multipathd daemon itself already listens on events from the udev socket; it should be pretty trivial to convert that to socket activation. And, of course, we need to solve the mount problem. Last I've heard was that systemd _won't_ be handling mounting, which in effect means we cannot mount any systems provided via multipath ... What is the status here?

It fully support mounts on boot, dynamically created, or on hotplug, with or without automounter support. But it will not assemble/handle/know anything about any dm/md devices.

Right. The tool to do that would probably be some raid-assembly daemon that replaces the insanity in current shell scripts and called tools that scan /dev. There is no plan currently to integrate any raid-assembly into systemd natively.

As you can see, that bugzilla got closed 19th July. It was linked to another one 723357 which is also closed, but the comment #2 there suggests there is still a problem to be dealt with: I'm not sure why udev synchronization is failing during startup, but it is. Ben, is that still a problem to be investigated? Alasdair ^ permalink raw reply [flat|nested] 8+ messages in thread
