Hi all,

I am trying to test Mondorescue reinstall from mondorescue iso in expert mode.

I tried to rebuild the lvm structure but lvcreate failed :

The device /dev/dm-0 is not created, then udev failed for creating others symlink ?

udevd --debug --daemon

"udevadm monitor" show that all devices are added, then a kernel event "remove" delete all.

On the mondorescue expert mode system,

# udevadm monitor --environment 

monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

The normal behaviour on the running system mondo archived is (with systemd) : 

monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

My knowledge of the subject is very limited, any suggestions would be welcome.
