copyoffload and ECOL_COPY_INTERNALERROR

ANCORON_LUCIFERIS

Hi all,

I hope that someone can help me with this.

I am testing an implementation for server-side copy using the NetApp ZAPI from Java.

My use-case is to copy a file from one volume/qtree to another. As I cannot guarantee that the destination already exists (which is demanded by the copyoffload) I am creating an "empty" file like this:

  1. file-write-file (path = destination-file, offset = 0, data = "00")
  2. file-truncate-file (path = destination-file)

After that, the copyoffload-copy-start command starts successfully and it seems to be working, but if I then check progress with a copyoffload-copy-status command I get the following:

<netapp version="1.1">

  <results status="passed">

    <copy-status>

      <copyoffload-status-info>

        <copyoffload-state>completed</copyoffload-state>

        <source-path>/vol/myvol/test.raw</source-path>

        <destination-path>/vol/myvol/copy.raw</destination-path>

        <length>251463</length>

        <copy-id>7ffba310-457a-11e2-9385-000000000000</copy-id>

        <bytes-copied>251463</bytes-copied>

        <copyoffload-error>15015</copyoffload-error>

      </copyoffload-status-info>

    </copy-status>

  </results>

</netapp>

So, it says "completed", but nevertheless has an error code set (which is ECOL_COPY_INTERNALERROR) and when I stat the target file I get this:

<netapp version="1.1">

  <results status="passed">

    <file-info>

      <name>/vol/myvol/copy.raw</name>

      <file-type>file</file-type>

      <creation-timestamp>1355279824</creation-timestamp>

      <modified-timestamp>1355279833</modified-timestamp>

      <changed-timestamp>1355279833</changed-timestamp>

      <accessed-timestamp>1355279824</accessed-timestamp>

      <perm>1064</perm>

      <owner-id>0</owner-id>

      <group-id>0</group-id>

      <file-size>0</file-size>

      <hard-links-count>1</hard-links-count>

      <inode-number>12056</inode-number>

      <acl-type>no_acl</acl-type>

      <bytes-used>0</bytes-used>

    </file-info>

  </results>

</netapp>

So, what's happening here?

This was with the simulator 8.0.1.
