udev im lxc funktion nicht richtig

void · 1. Juni 2020

Hi zusammen,

ich habe wie hier beschrieben das DVD+-RW in eine debian lxc weitergereicht auf meinem qnap.

soweit geht auch alles, allerdings ist udev seltsam.

Code

udevadm info -a /dev/sr0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

  looking at device '/block/sr0':
    KERNEL=="sr0"
    SUBSYSTEM=="block"
    DRIVER==""
    ATTR{range}=="1"
    ATTR{hidden}=="0"
    ATTR{events}=="media_change eject_request"
    ATTR{events_async}==""
    ATTR{ro}=="0"
    ATTR{discard_alignment}=="0"
    ATTR{size}=="1362576"
    ATTR{capability}=="119"
    ATTR{ext_range}=="1"
    ATTR{events_poll_msecs}=="2000"
    ATTR{inflight}=="       0        0"
    ATTR{removable}=="1"
    ATTR{alignment_offset}=="0"
    ATTR{stat}=="      91        0     3432     9672        0        0        0        0        0     9084     9672"

  looking at parent device '/block':
    KERNELS=="block"
    SUBSYSTEMS==""
    DRIVERS==""

Alles anzeigen

und für /dev/cdrom dasselbe. Dies ist ein manuell angelegter symlink auf /dev/sr0 weil programme wie eject dann keine parameter brauchen.

Ich wollte nunmehr ein script starten, wenn eine Scheibe eingelegt wird ins Laufwerk. also habe ich in /etc/udev/rules.d/99-auto-instert.rules

Code

ACTION=="change", SUBSYSTEMS=="block", KERNEL=="sr[0-9]*", RUN+="/usr/bin/detectCD.sh"

jedoch löst dieses script anscheinend nie aus, obschon das event vorkommt:

Code

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


KERNEL[32162.657079] change   /block/sr0 (block)

im Testmodus geht es aber wohl:

Code

sudo udevadm test  /block/sr0 -a change
This program is for debugging only, it does not run any program
specified by a RUN key. It may show incorrect results, because
some values may be different, or not available at a simulation run.
