Somehow you remind me of the story "the boy who cried wolf" (Look, look! The wolf ate my disk space) :P > > First I do "zfs list" onto TempStorage/Backup which reports 800GB.

I know there is 620GB worth of data, which I can not > access. Where is my data, and how can I access it?

Well, close anyway. See http://hub.opensolaris.org/bin/view/Community+Group+zfs/faq/#HWhydoesdu1reportdifferentfilesizesforZFSandUFSWhydoesntthespaceconsumptionthatisreportedbythedfcommandandthezfslistcommandmatch - zfs will show a "fake" number in df's "Size", to be roughly the sum of "Used" + "Avail" for that particular filesystem. "fake", as in this not the actual pool size. So in short, for filesystem/dataset in the same pool, df will show the same "Avail", but different "Used" and "Size". -- Fajar _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
