    Dear friends,

    I have been running M2P on various Raspi at my household all served from an LMS-server installed on a synology NAS. It worked for 2 years with only minor problems (some clients always get lost and are only rescanned after a reboot). But recently, one client, a pi zero with DAC+ Zero 1.0.1 lost contact and could not be brought back to live with a reboot.

    First I could connect to the web interface which informed me that
    a) there was no license for M2P
    b) the right DAC has not been chosen and
    c) that there is an M2P update to 2.4.7. available.

    I tried entering the license (I have full 5 years license) and also tried changing the DAC but both failed. After reboot the system still did not know about the license nor did it accept the selected DAC. The device had full access to the internet, verified with ssh and ping from the device.

    Hence I thought I start with the update to 2.4.7 and then debug the other problems. Hence back to reinstall:

    1. Removed SDcard
    2. reformatted SDcard
    3. Downloaded new 2.4.7 M2P image
    4. Burned image to SD card
    5. Activated WPS (required for WLAN scan)
    6. Rebooted pi with prepared SDcard


    – pi is connected to network and accessible via ssh
    – but Web interface is not available. Scanning the logs it seems, that the system is inable to write to the SDcard. There is no write protect plugin enabled, its a fresh install.

    Hence now I am a bit clueless. Might that be a defective SDcard which only shows the problem once the system boots? But fsck does not hint to any problem:

    sudo fsck
    fsck from util-linux 2.25.2
    e2fsck 1.42.12 (29-Aug-2014)
    /dev/mmcblk0p2: sauber, 93062/448224 Dateien, 563505/1893296 Blöcke
    fsck.fat 3.0.27 (2014-11-12)
    /dev/mmcblk0p1: 185 files, 2739/7673 clusters

    Here is the log from apache etc:

    Hi Marc,

    Thanks for sharing this detailed post, I will see if anything special could be done. For now, though please try another microSD if you have any, to rule out a likely faulty SD card as source of error.

    Dear Heiner,

    I tried a new SDcard and it works again. I know its not a big deal but the faulty SDcard has been purchased with a pre-installed m2p from your shop last year, 22.5.2018. It is a Samsung 8GB. I couldn’t find any information about warranty but I guess since it is not even one year it should be covered. Any chance of a replacement?
