I haven’t yet run out of space, but I seem to be bleeding storage space like crazy on my EX2 (2x3TB Red, JBOD, v. 2.10.310), which I received Dec 5 this year. I manually mirror files from a subdir of Public on Vol 1 to Vol 2, big GB mp4s. Aside from a 65 GB .dmg, everything of any size on the EX2 is just those mp4s.
tl;dr: Recycle bin can contain a lot of used storage, and seems to do so on Macs, even though you think you’re using AFP rather then SMB (Time Machine can’t use SMB). Waiting for Support to respond wi the best way to deal with this on a Mac.
Details included for Support and WDs dev team:
Vol 2 looks fine, showing 675G usage, about as expected, in the Share profile of the dashboard. Other shares except Public show usage in KB except Vol 1, which also shows 675GB usage, but total available space is << 5TB at 3.96 GB.
OS X 10.11.1 shows 2.15GB available on Vol 2, but only 1.77GB available on Vol 1, though they have the exact same content wrt large mp4 files.
From the shell, things are anomalous-looking, but bottom line is:
EX2: df -h
/dev/sda2 2.7T 1.0T 1.6T 39% /mnt/HD/HD_a2
/dev/sdb2 2.7T 712.8G 2.0T 26% /mnt/HD/HD_b2
Groveling down in Vol 1 with du -sh, I get this anomaly:
EX2: du -sh /mnt/HD/HD_a2/
EX2: du -sh /mnt/HD/HD_a2/*/
HD_a2 is using 1.1TB, but summing its subdirs shows only 675G. A chunk is missing…
There are no symlinked subdirs messing up the total, as seen here:
EX2: ls -l /mnt/HD/HD_a2/

Where is the 1.1TB - 675GB missing space?
Looks like it’s mostly here:
EX2: du -sh /mnt/HD/HD_a2/.!*
(What a dir name!) I did turn on Recycle bin, but noted the following in the Manual:
The Recycle Bin is only available for Windows SMB files.
Note: Recycle Bin is only available for SMB protocols.
(The first statement needs a bit of work, since SMB is a protocol, not a file type and no longer a creature of Win exclusively)
The Finder does see the Recycle bins and they do have GBs in them, many GBs on Vol 1.
Since it’s a Mac, and top on the EX2 shows /usr/sbin/afpd going crazy at 50-70% CPU and smbd and nmbd at 0% CPU when I copy an mp4 to it from a different NAS, I believe(d) I am not using SMB (or else the note above is wrong, and Recycle is enabled for AFP). To be clear, there are no Win PCs in the place, only Macs, iThings, and a couple WD MyBook Lives, and I have no backups scheduled on any computer except Time Machine to USB drives.
I had turned on the Recycle on both Vols in case friends or family came a-visiting with Win PCs in hand. I haven’t set up any Active Directory on the NAS, and don’t want to, at least not until it’s needed.
So because no AD setup, I can’t find the Clear button referenced on p 118 (I assume it shows up somewhere in the AD setup, the Manual doesn’t really say where it’s to be found):
The Recycle Bin contains any files deleted from the WD My Cloud EX2 device. To clear the recycle bin for your device, click Clear.
In any case the Manual seems out-of-date wrt latest firmware, with many screens appearing different.
I tried disabling Recycle bins on both Vols but the space is not reclaimed,
A thought about Dashboard: when user disables Recycle and there are files in the Bin, ask whether s/he wants to delete the files; could save some grief.
I guess I could use the shell to delete the files, but the dir name /mnt/HD/HD_a2/.!@#$recycle is a beast to work with in bash.
I did try deleting Recycle bin contents from Finder before I disabled it in the Dashboard, but there was no apparent progress, so I hit Stop in the Finder progress window. I do see that some space was freed up during the apparently inoperative Finder delete:
EX2: du -sh /mnt/HD/HD_a2/.!*
a gain of 110 GB, so maybe I’ll re-enable Recycle and retry the Finder delete.
Anyway, I’ve got a ton of space still in use on the Recycle bins, so this may be the problem for other folks too, especially if they’ve turned on Recycle, deleted lots of stuff, then turned it off again, rendering the storage usage effectively invisible without Ninja shell tricks.
