All,

I've also noticed that since the update, the GFS products are coming through 
without any product ID on them other than the file name.

Before, they had unique product IDs after the exclmation point, like this (from 
an ldmadmin watch from 2021)

I have some cases where I had been keying in on that to only save certain 
fields to a file, and now they aren't getting saved because it doesn't see that.

For what it's worth..

Subject: Re: [conduit] NCO Conduit Transition to RHEL8

Hi Daryl,

For some unknown amount of time, there has been duplicate NDFD data on CONDUIT 
that would come with two separate product IDs, though the data was identical.  
Here is an example of the differences; the two products were otherwise bytewise 
identical:

/common/data/products/NDFD/grib2/YCUZ98_KWBN_121351.grib2 
!grib2/nwstg/NWS_0/#000/202310121400F058/SPED/10 m HGHT! 000042
data2/ndfd/YCUZ98_KWBN_121351.grib2 
!grib2/nwstg/NWS_0/#000/202310121400F058/SPED/10 m HGHT! 000042

I have been in talks with NCEP about this and I know they were looking into it; 
while I wasn't aware of any plans, it would appear they have 
consolidated/rectified the different product IDs with this update.  From my 
records it looks like the latter pattern stopped around 10/12 14Z, the former 
pattern continues to be used.

If you search using the former product ID pattern, do you see all the expected 
NDFD products then?

Greetings,

Since this transition, I am noticing that NDFD data is not flowing over 
CONDUIT.  Anybody else able to verify?

Hello CONDUIT Users,

The start date of the transition of NCO's Conduit servers to RHEL8 was pushed 
back by one day due to Critical Weather Day on Tuesday 10/10. Therefore our 
migration to the new systems began today, Wednesday October 11th. The 
transition will still take place over three days with our operational servers 
now planned to migrate tomorrow, Thursday October 12th at ~1300z.

Changes on your end are not necessary and we are anticipating a seamless 
transition. If however you do encounter issues that are not resolved by an LDM 
restart, please report them to NCO Dataflow 
(ncep.pmb.dataflow@xxxxxxxx<mailto:ncep.pmb.dataflow@xxxxxxxx><mailto:ncep.pmb.dataflow@xxxxxxxx<mailto:ncep.pmb.dataflow@xxxxxxxx>>)
 as soon as possible with a subject line that includes the text "CONDUIT Issue".

Thank you
