Problem with zwave usb device running in docker container

Setup, Configuration and Use Runtime
,
1

Using latest openhab/openhab:amd64-online docker image (openhab2 build #477) and the zwave binding. The zwave device is an aeotect z-stick gen5 usb stick. The container is started using docker-compose and the following docker-compose.yml file:

version: '2'
services:
  openhab:
    image: 'openhab/openhab:amd64-online'
    restart: always
    volumes:
      - '/etc/localtime:/etc/localtime:ro'
      - '/etc/timezone:/etc/timezone:ro'
      - '/export/openhab2/userdata:/openhab/userdata'
      - '/export/openhab2/conf:/openhab/conf'
    ports:
      - "8080:8080"
      - "5555:5555"
    devices:
      - "/dev/ttyACM0:/dev/ttyACM0:rwm"
    command: 'server'

When started the following error is thrown by the runtime when the thing is added:

 java.lang.UnsatisfiedLinkError: /openhab/userdata/tmp/libNRJavaSerial_openhab_0/libNRJavaSerial.so: /openhab/userdata/tmp/libNRJavaSerial_openhab_0/libNRJavaSerial.so: failed to map segment from shared object

Any clues on how to resolve the issue?

The complete output when starting the container with the thing added follows:

Have you seen this issue? https://github.com/docker/compose/issues/1339

TL;DR: /tmp needs to be executable

Yes I had - but had discarded it my first troubleshooting attempts. Turns out the issue is the same!

I’m running the docker containers on a NAS with the OpenMediaVault distribution. The volumes mounted in the openhab container are to openmediavault shares. By design, openmediavault creates/mounts shares with the noexec flag.

Instead of remounting the share with exec rights i simply created a soft link for the userdata/tmp to the real /tmp of the NAS and is now ready to continue my migration efforts from openhab 1.7.1 (and 1.8.3) to 2.0.

Thanks Rickard for the hint.
