It's in knight as well as in master. Procedure to (hopefully) reproduce is as follows:\r\n\r\nHave something like \r\n````\r\npool/old_name/tree/subd1\r\npool/old_name/tree/subd2\r\n````\r\n\r\nthen use:\r\n\r\n````\r\nsudo zfs rename pool/old_name/tree pool/tree\r\n````\r\n\r\nthis works. Now if you received new datasets so you have a new batch of sub_datasets:\r\n\r\n````\r\npool/old_name/tree/subd3\r\npool/old_name/tree/subd3/blah\r\npool/old_name/tree/subd4\r\n````\r\n\r\nzfs list would now look like:\r\n\r\n````\r\npool/tree/subd1\r\npool/tree/subd2\r\npool/old_name/tree/subd3\r\npool/old_name/tree/subd3/blah\r\npool/old_name/tree/subd4\r\n````\r\n\r\nnow issuing\r\n\r\n````\r\nsudo zfs rename pool/old_name/tree/subd3 pool/tree/subd3\r\n````\r\n\r\nresults in:\r\n\r\n```\r\nAssertion failed: (!clp->cl_alldependents), function change_one, file libzfs_changelist.c, line 507.\r\nAbort trap: 6\r\n```"}}
