How to update /dev directory after creation of new partition on a disk? I have the udev installed, it works perfectly except this. The new devices appear only on reboot.

Command partprobe from sys-block/parted also does the job well. Use is like this:

# partprobe

or for a particular device only (e.g. /dev/sda):

# partprobe /dev/sda

You may use kpartx from sys-fs/multipath-tools, if you modified the /dev/sda drive:

# kpartx /dev/sda

The partx utility from sys-apps/util-linux could be used instead, but it won't work with LVM.
