Use $ zfs get usedbysnapshots file_system, and you will see where the space went. Listing the snapshots and looking at the USED column does not give you this information because it only shows what would be freed if _only_ this snapshot were destroyed. By destroying all of them, a lot more might become available. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

When I run df -k I see that the pool is using ~650GB of space and has only ~120GB available. Running zfs list shows that my pool (localpool) is using 1.67T.
