Hi Zdenek, Sorry I passed over your post. May I ask you how you are going to handle this issue by udev? The problem is *not* a scan of devices to update dev-cache but a scan of devices to update lvm metadata cache in memory by lvm command. Currently lvm does not have a kind of metadata cache on a device (e.g. /etc/lvm) and lvm command has to get metadata information stored on each PV whenever it is executed. It is helpful if udev can handle this issue, but I'm wondering how it can do it.
