see https://github.com/zfsonlinux/zfs/pull/6616 for the fix in ZFS on Linux 0.7.3 (on the sender side). not yet backported to Open-ZFS, and thus not in FreeBSDs ZFS either.
this is not really a bug in ZFS on the receiver side, it was an accidental break of backwards compatibility. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1733230 Title: 'zfs recv' hangs when receiving from a FreeBSD zfs Status in zfs-linux package in Ubuntu: New Bug description: When creating a pool snapshot on a freenas/freebsd like this: ``` root@freenas:~ # uname -a FreeBSD freenas.local 11.0-STABLE FreeBSD 11.0-STABLE #0 r321665+25fe8ba8d06(freenas/11.0-stable): Mon Sep 25 06:24:11 UTC 2017 root@gauntlet:/freenas-11-releng/freenas/_BE/objs/freenas-11-releng/freenas/_BE/os/sys/FreeNAS.amd64 amd64 freenas# zpool create tank gptid/62a26be7-cd4a-11e7-927b-0800278dcda9 freenas# dd if=/dev/zero of=/tank/ur.bin bs=64K count=1 freenas# zfs snap tank@example ``` And trying to `zfs send | zfs recv` it to an ubuntu zfs like this: ``` space@ubuntu:~$ apt-cache policy zfsutils-linux zfsutils-linux: Installed: 0.6.5.11-1ubuntu3 Candidate: 0.6.5.11-1ubuntu3 Version table: *** 0.6.5.11-1ubuntu3 500 500 http://us.archive.ubuntu.com/ubuntu artful/main amd64 Packages 100 /var/lib/dpkg/status space@ubuntu:~$ lsb_release -rd Description: Ubuntu 17.10 Release: 17.10 root@ubuntu:~$ ssh root@freenas zfs send tank@example > freenas11.zfssend root@ubuntu:~# cat ./freenas11.zfssend | zfs recv tank/something ``` The `zfs recv` process burns 100% CPU and hangs forever.
