--- Comment #3 from Adam McDougall <ebay@looksharp.net> ---
I noticed recent FreeBSD 13 systems consuming more space than expected and I
traced it down to the new autotrim zpool property on my 13 installs. I can
watch gstat -d output during/after data deletions and BIO_DELETE IO does not
happen. If I manually trim the pool or enable zpool set autotrim=on rpool then
deletions happen. I am not relying on what state the autotrim property says, I
am basing my conclusions on measurements. Unless something has changed within
the last few months, I believe this is still the case.
