#OpenZFS includes arcstat, their standard tool to interrogate ARC stats.
It's in python, so #FreeBSD doesn't install it.
It'd be really nice to have this as a package before #openzfsmastery comes out.

The OpenZFS User Days wrapped up yesterday, and Developer Day kicks off today!
Great discussions on hardware costs and shortages, how users work with existing OpenZFS features, and what they'd like to see next.
Looking forward to more ideas and insights!

Over two-thirds of HDD capacity shipped in 2026 will be SMR, according to Western Digital's projection at the OpenZFS Summit.
SMR dates back to 2003, but adoption is accelerating. Now filesystems must adapt: host-managed SMR drives don't support conventional random writes.

OpenZFS 2.3.0以降のZAP縮小に不具合、チェックサムが一致する管理情報破損を再現
OpenZFS 2.3.0以降の管理表で、領域の縮小処理が拡張途中の領域を誤って再利用する不具合が報告された。破損した管理情報にも正常なチェックサムが付くため、データの検査値が一致しても、ファイルの参照関係が正しいとは限らない。
