I'm now looking at the udev monitor and also set the loglevel to debug and I can see that udev is processing the multipath events, hence creating the /dev/mapper entries (but not the partition entries). But there is never anything called that would create the /dev/dm-* devices and the 95-kpartx rule is also never called it seems. I have now rigged it to run a script on boot that calls mkdnod and kpartx, but of course I'd still like udev support. I have not been able to get any answer from ubuntu guys, so is it a fact that multipath is basically not supported under ubuntu ? What would be the next best distribution thats free of annual license fees ?
