Hi,
I’ve been having some trouble with my WD My Cloud EX 4100 (Firmware Version: 2.30.181) for a while now. It had a low availability and was randomly creating hundreds of shares (Public_1 through Public_5xx). To mitigate this issue I did a system restore. This helped with the shares but now the DLNA Media Server does not work right anymore (immediately after the restore the unit automatically installed a new firmware.) It shows only a small subset of the movies that are on the share. The rest of the files show up on my connected computers though.
I logged into the Twonky interface (http://192.168.1.123:9000/webconfig#advanced), restarted the server and had a look at the log files:

That last error had me worried because the My Cloud interface reports hundreds GB of free space. I SSHd into the unit and ran df -h:
root@WDMyCloudEX4100 / # df -h

Two of the devices report 100% usage which could be related to my issues.
Here’s df -i’s output:

I don’t know how to proceed from here. Any ideas?
I only use one encrypted disk right now btw. Adding my other disks is what prompted the problem with the hundreds of randomly created shares so I took them out. They are now resting uselessly on my desk
