Re: [dm-devel] configure MD3000 episode 2



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 ?

Thank you very much again,
Thomas
