Hi List, Im not sure, if the udev-rules of lvm is creating this. Im Using Ubuntu 12.04.4 + lvm git yesterday, compiles with --enable-udev_sync --enable-udev_rules. Here my testing results: root@dmicrash\:rules.d# vgcreate myvg /dev/sdc1 /dev/sdd1 Volume group "myvg" successfully created root@dmicrash\:rules.d# lvcreate --name test --size 20G myvg Logical volume "test" created root@dmicrash\:rules.d# parted /dev/myvg/test mklabel msdos root@dmicrash\:rules.d# parted /dev/myvg/test mkpart primary 0% 40% root@dmicrash\:rules.d# ls /dev/mapper/ control myvg-test myvg-test1 The device myvg-test1 was created automatically (normally this is done by kpartx?). I disabled gnome-automounter, didnt help. I tried to monitor this with udevadm --monitor, but i didnt get displayed the rule-file who did this. Any hints? Tfh!
