Well I never. Just by chance I did zfs list -t snapshot, and now it shows a 1TB snapshot which it wasn't showing before. bunker:~# zfs list -t snapshot NAME USED AVAIL REFER MOUNTPOINT tank0@snap 1.00T - 2.47T - I know it wasn't showing before - here's my first post with the output of the same command: http://www.mail-archive.com/zfs-discuss@opensolaris.org/msg43138.html Have destroyed the snapshot, all now as it should be. bunker:~# zfs list NAME USED AVAIL REFER MOUNTPOINT tank0 1.48T 1.20T 1.48T /mnt/tank0 Very odd. Pool history is pasted here: http://pastebin.com/TRWcebSs Thanks for the input.
