zpool shows raw storage, ie doesnt take into account the raid levels redundancy requirements. zfs shows what a file system/dateset can use. Things like quotas can make this different than the pool size. I think it also takes into consideration the raid requirements, but i may be wrong there. df, can start to go a bit mad when you enable compression and dedup, as the projected capacities can actually increase depending on the compression and dedup ratios you are achieving. In the case you state its probably a quota as the mismatch is so big. On 21 August 2016 at 01:27, Paul Kraus <paul@kraus-haus.org> wrote: > > > On Aug 18, 2016, at 7:32 AM, Eugene M.
