Re: [conduit] Missing grids from some 0.5 gfs files on CONDUIT

I'm assuming the problem hasn't been fixed yet, but just for info, so far the same thing has happened with the 18 UTC 23 run for

F021, F030, F036 and F087 (data is currently in through F204)

Pete,

Apologies for the issues. We have just determined that this is a disk read/write issue which is why you see it as random. We have engaged our IT folks to resolve this issue. We will let you know as soon as the problem is fixed.

    All,

    We have noticed a strange problem with the grids coming in for the
    0.5 degree GFS files. The problem started with the 12 UTC run of
    the 2015/04/22 run, and several files (though not always the same
    ones) have been missing grids in each run since. The complete
    files contain 366 grids, the incomplete files always contain 327
    and are always missing exactly the following grids:

    I don't think it's a latency issue for us, because our latencies
    for conduit have been < 30 seconds or so for at least the past 3 days.

    One curious thing, the files are complete on motherlode.ucar.edu
    <http://motherlode.ucar.edu>, but the files that we have as short,
    have a later modification time than the rest. For example, for the
    12 UTC 23 run, we were missing grids for the F021, F102, F123 and
    F252 times. Here's a subset of the times on motherlode that shows
    these files:

    We are feeding redundantly from conduit.ncep.noaa.gov
    <http://conduit.ncep.noaa.gov> and ncepldm4.woc.noaa.gov
    <http://ncepldm4.woc.noaa.gov>

    Ideas?

    Here is a (I think) complete list of the times that had short
    files since 12UTC 4/22. I'm guessing all of these files are
    complete on motherlode, but have a later modification time than
    the rest of the run.
