LED - RED (constant) and i can't see files anymore

That df output still doesn’t look right.

/CacheVolume and /DataVolume should be /dev/sda4. Here’s what I get:

WDMyCloud:~# cd /
WDMyCloud:/# df -h

    /dev/sda4       3.6T  1.9T  1.7T  53% /nfs/Public
    /dev/sda4       3.6T  1.9T  1.7T  53% /nfs/Media

There’s a thread that solved this somewhere, and it involved mounting sda4… can I find it…?

Hmm… maybe this one:

which used

mount /dev/sda4 /DataVolume
mount -bind /DataVolume/cache /CacheVolume

or this one:

which used

/etc/init.d/mountDataVolume.sh

or this:

which has a very similar df result to yours, including the /dev/root for /CacheVolume, and Fox_exe suggested:

mount -t ext4 /dev/sda4 /DataVolume

I’ll be honest with you: this is getting beyond my pay grade… Linux file system mounting stuff is just a bit beyond my experience, and you may be better off asking for assistance from more knowledgeable types. @Bennor, perhaps?

But I note that mounting /dev/sda4 as /DataVolume seemed to do the trick in two of the cases above, with different degrees of explicit control (i.e. Fox_exe enforced the ext4 file type, rather than letting it automatically decide; it will be ext4).
