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? > -- Sphinx of black quartz judge my vow.
