    after the rollback, per was the same version , and napp-it had same issue.

    Here are our zfs filesystems:

    # alias df
    alias df='zfs list -t filesystem'
    sys4  ~ # df
    NAME                                        USED  AVAIL  REFER  MOUNTPOINT
    data                                        175G  1.68T  27.2K  /data
    data/backup_napp-it                         265M  1.51T  37.8M

    rpool                                      23.9G   437G  24.5K  /rpool
    rpool/ROOT                                 5.82G   437G    19K  legacy

    rpool/ROOT/omniosvar                         19K   437G    19K  legacy
    rpool/ROOT/pre_download_16.03f_1463010047     1K   437G  2.92G  /
    rpool/ROOT/pre_napp-it-16.02f                35K   437G  1.63G  /
    rpool/ROOT/pre_napp-it-16.03f                41K   437G  3.19G  /
    rpool/export                                 38K   437G    19K  /export
    rpool/export/home                            19K   437G    19K  /export/home

    I had done this to roll back:
     zfs rollback  -r  rpool/ROOT/omnios at 2016-05-19-150000

    In case you know  omnios/napp-it ,  is there another file system which
    should be rolled back to fix the napp-it storage?
