Gilbert,
On the off chance that the problem you are seeing is on weather2,
I SSHed from weather3 to take a look. What I found was that none
of the ldm-mcidas decoding actions were running, and the ~ldm/logs/ldmd.log
file was full of pipe errors like you said.
I then found that the LDM was not running as the user 'ldm', but, rather,
as the user 'mcidas', and this was your entire problem. So, I logged
on as 'mcidas' and stopped the LDM:
<login as 'mcidas'>
ldmadmin stop
and then logged on as 'ldm' and started the LDM:
<login as 'ldm'>
ldmadmin start
Now, the pnga2area decode processes are working correctly.
I see, however, that proftomd is failing:
Nov 24 21:02:18 proftomd[17038]: Starting up
Nov 24 21:02:18 proftomd[17038]: could not open /data/mcidas/.tmp_netcdf.QoJRvX
Nov 24 21:02:18 proftomd[17038]: Exiting
What is happening here is that the FSL wind profiler decoder is
trying to create a temporary file in /data/mcidas. Since this directory
does not exist, the process was failing. I changed the proftomd
entries in ~ldm/etc/pqact.conf:
were:
# Hourly Summary
FSL2 ^FSL\.NetCDF\.NOAAnet\.windprofiler\.01hr
PIPE -close
proftomd -vl /home/ldm/logs/ldm-mcidas.log -d /data/mcidas U2 WPRO 81
##### PIPE -close proftomd -d /home/data/mcidas U2 WPRO 81
#
# 6-minute
FSL2 ^FSL\.NetCDF\.NOAAnet\.windprofiler\.06min
PIPE -close
proftomd -vl /home/ldm/logs/ldm-mcidas.log -d /data/mcidas U6 WPR6 91
##### PIPE -close proftomd -d /home/data/mcidas U6 WPR6 91
changed to:
# Hourly Summary
FSL2 ^FSL\.NetCDF\.NOAAnet\.windprofiler\.01hr
PIPE -close
proftomd -vl /home/ldm/logs/ldm-mcidas.log -d /home/data/mcidas U2 WPRO
81
##### PIPE -close proftomd -d /home/data/mcidas U2 WPRO 81
#
# 6-minute
FSL2 ^FSL\.NetCDF\.NOAAnet\.windprofiler\.06min
PIPE -close
proftomd -vl /home/ldm/logs/ldm-mcidas.log -d /home/data/mcidas U6 WPR6
91
##### PIPE -close proftomd -d /home/data/mcidas U6 WPR6 91
I then checked the integrity of the ~ldm/etc/pqact.conf file and sent
pqact a HUP signal telling it to reread the file:
ldmadmin pqactcheck
ldmadmin pqactHUP
Waiting around until profiler data came in shows that it is now being
decoded correctly:
Nov 24 21:08:44 proftomd[17952]: Starting up
Nov 24 21:08:44 proftomd[17952]: Decoding 2003328.2054 data into
/home/data/mcidas/MDXX0098
Nov 24 21:08:44 proftomd[17952]: WARNING: MD #cols 35 < dataset #stn 35
Nov 24 21:08:44 proftomd[17952]: Exiting
So, the file is being written now. The warning being issued by proftomd
is a separate issue that I will need to look into further.
I then noticed that a lot of the data files in /home/data/mcidas had
not been scoured in quite awhile. I traced this down to the following:
1) the McIDAS scouring was being done (through a cron job running mcscour.sh)
by 'mcidas' -- this is not bad, but
2) the output log file for the scouring, /home/mcidas/workdata/scour.log,
was owned by 'ldm' and was not writable by 'mcidas'
I commented the cron initiation of mcscour.sh in the 'mcidas' account
and added the same entry to the 'ldm' account. In doing this, I
also:
1) made a copy of /home/mcidas/workdata/mcscour.sh in /home/ldm/decoders
2) added a cron entry to run that copy of mcscour.sh
3) added a cron entry to rotate ldm-mcidas log files
I think things are running correctly now. Please let me know if you see
strange things.
