Bug 196533

System: FreeBSD AMD64 10.1-RELEASE-p3. Base standard distro with GENERIC kernel. All binaries from main Repo

System has a ZFS Root (Mirrored Drives) and 2 3-Disk pools (RAIDZ1).

Issue:

Inadvertently tried to clone a snapshot from pool1 to pool2 (instead of using send/receive)

Result was a zfs command core dump. 

Expected result: Error message

Command used:

% sudo zfs clone pool1/jails/base@base10.1-p3 pool2/jails/jailclone

% sudo gdb -c ./zfs.core /sbin/zfs
