My personal recommendation is to keep .zfs directory hidden and/or perform only basic operations on entries under it while ensuring that there is only one process at a time that peeks there. The gfs stuff that handles .zfs operations is really very broken on FreeBSD[*]. If you are interested, I have a patch that should some of the mess, but not all. [*] To see what I mean run several of the following shell loops in parallel: while true; do ls -l /pool/fs/.zfs/ >/dev/null; done -- Andriy Gapon
