after reading a lot around the web about all the problems the EX4 is having regarding its media server eating up all the CPU and constantly grinding the disks I tried everything I could find on Google and at the moment I am a bit stuck. My device has firmware 2.11.133 and this is what I have gone through.
Stopping wdmcserverd and wdphotodbmergerd works through SSH as described on many tutorials.
update-rc.d wdmcserverd disable and the same for wdphotodbmergerd does not work, I get an error that update-rc.d is not found.
Using chmod 644 on wdmcserverd and wdphotodbmergerd to stop them from being executed doesn’t work either, the privileges are restored after every reboot.
Renaming both services results in the same outcome: they are restored after reboot.
Trying to change the excludepath in the wdm.xml with a text editor and adding “shares” doesn’t change anything as the wdm.xml is also restored after reboot.
Changing the twonky server settings for not searching pictures is not possible here or I am blind as I didn’t find this option. There is a prompt to write in exclusions and putting “shares” there doesn’t do anything, wdmcserverd rattling away after reboot.
So WD, as you might already know (sigh), this device is not capable to run all the useful stuff you wanted it to run without shredding the hard disks and lots of guides here and on other sites in the internet are a testament to that. Please give us at least an option to kill both these services for good so that we don’t have to SSH into the device EVERY REBOOT!
Luckily I am not in the camp who have bought this thing for its retail price, the price I paid for a used unit amounts to the same price of only the four hard disks in it so I can move on to another solution if nothing helps. But I’d rather like WD to step up and fix that thing fast please!
