And then there is a question what is specific about that file which is triggering the receive error… is it possible to get hands on send stream maybe? (I’m investigating one send+receive case which is triggering receiving pool to get to suspended state and it is quite a challenge).
Here is the ZFS dump (1.8GB) <https://imk-asf-mipas.imk.kit.edu/users/grabow/> : 32@20100825 32@20100825_xxhsum features_importable features_nonimportable + xxhsum checksum , + features active/enabled on 2018/4 pool where it can be imported, and features on a very recent pool where it can't. The zfs filesystem contained is Results/imk/32. -- Dr.Udo Grabowski Inst.of Meteorology & Climate Research IMK-ASF-SAT https://www.imk-asf.kit.edu/english/sat.php KIT - Karlsruhe Institute of Technology https://www.kit.edu Postfach 3640,76021 Karlsruhe,Germany T:(+49)721 608-26026 F:-926026
