Just curious, what `ls -la /storage/' and `ls -la /storage/.zfs/s*` show?
It's plain weird.

Let's take this one for example. It's not mounted! It shouldn't be listed in next command output.

This is not a zfs dataset. This is a file. It has no relevance to named dataset. And it drains space from /storage.

There's also another discrepancies in your output like: * "av.https-ict.nl..OS" != "av.https-ict.nl.OS", seems like copy-and-paste error(?); * "bestandonline.https-ict.nl.DATA" and "documentatievm.https-ict.nl" doesn't exist in datasets, it looks like correspondent datasets were already removed, but not files.
It definitly looks like the reserved space for the zvols is counted in /storage,
but the written data is counted for /storage as well, instead of the zvols..
Will an upgrade fix this?
