  • Closed as program error.

Error description

  • When afmFastCreate is configured and a normal file gets copied -
    it sets the cache/primary mtime at the home/Secondary during
    file create time itself.
    Later if Write gets interrupted mid-way and later a Resync is
    run on this fileset - the same file is not copied over fully
    stating that the file is already in sync. It involves a small
    race to get here.
