Thank you for that. I looked at your thread on the illumos zfs list, and from what I gather, if you aren't wedged into a state where you have to import read-only, you don't have to worry about leaked data in your pool, correct? I always have a small number of 'deferred free' blocks that's always somewhere between 8 and 10: 9 108K 15.5K 108K 12.0K 6.97 0.00 deferred free Also, if you run 'zdb -bb <pool>' on a live pool, you can get a bunch of: leaked space: vdev 0, offset 0x16464c2000, size 1048576 ... and then: block traversal size 14586265600 != alloc 14667571200 (leaked 81305600) which I believe is normal and unrelated.
