Is this ZOL tip or Linux specific? FWIW, the bug does not seem to reproduce on FreeBSD-current (r332158). However, it also does not reproduce on Ubuntu 4.4.0-116-generic running the ZFS stuff from Ubuntu.

See the test-case furthest down in the bug report. They were able to get it to reproduce on current linux distributions. The differences between older and newer distributions had to do with coreutils changes to the "cp" implementation between 8.22 and 8.23 Reverting this commit causes the bug to stop reproducing: https://github.com/zfsonlinux/zfs/commit/cc63068e95ee725cce03b1b7ce50179825a6cda5 https://github.com/zfsonlinux/zfs/commit/cc63068e95ee725cce0... [edit] An inspection of the following makes me think this is ZoL specific. https://github.com/freebsd/freebsd/blob/58941b0245fd8d3d5861206a07477e18635eafec/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zap_micro.c#L1146 https://github.com/freebsd/freebsd/blob/58941b0245fd8d3d5861...

Ubuntu was never affected. The regression started in 0.7.7 and Ubuntu is on 0.7.5. HEAD was affected until earlier today when the patch was reverted. I am not sure if the bad patch was ported to the other OpenZFS platforms.

  Debian Stable(jessie) is on 0.6.5.9 and Debian unstable(sid) is on 0.7.6 so they shouldn't be affected.

    Debian stable is stretch, released in june 2017. It's on 0.7.5 currently.

      correction, I hadn't updated my server in a while, stretch itself is on 0.6.5.9 also, but stretch-backports is on 0.7.6 (not sure when that happened exactly)
