devicemapper and udev events

Hi Ilya,

While working on multipath, I noticed that udev add event are not triggered when /dev/dm-0 etc. are created. Should I expect a udev add event for every device ? Or does it not apply to devices created by / with devicemapper ? 

Thanks in advance for your insights :-)

I'd expect an event - are you sure it's not triggered?  Are you using
udevadm monitor or is it just some udev rule not getting executed?

Thanks,

It's just that udev rules are not getting executed. Thanks for sorting out my confusion :-)
