Sure. I jumped onto cyclone and started looking in /data/ldm/mcidas. Sure enough, the files were eating up all of the filesystem (8 GB). The first thing I did was to manually delete three really old .XCD files. This freed up a few hundred MB of space, but it was not the problem. The next thing I did by hand was to delete all GRID* files that were of zero length. Next, I became 'ldm' and took a look at the crontab to see what was being run for data scouring. Crontab shows that ~ldm/decoders/mcscour.sh is to be run, so I took a look in it. The first thing I noted was that mcscour.sh had not been updated to scour all of the grids that McIDAS-XCD produces. Since the McIDAS GRID files are huge, this as probly your problem. I edited ~ldm/decoders/mcscour.sh and: changed: qrtmdg.k GRID 5001 6000 1 to: qrtmdg.k GRID 5001 6400 1 I then ran mcscour.sh by hand: <as 'ldm'> ~ldm/decoders/mcscour.sh After this ran, you now have a lot (like 6 GB) of free space in /data. So, it looks like the problem was that the GRID scouring entry in mcscour.sh needed updating to match the GRID files that the v2002 XCD GRIB decoder produces. >Thanks! No worries. You should be OK now. Please keep an eye on your disk space for a couple of days to make sure that things are working correctly. In particular, you should look at the mcscour.sh log file: ~mcidas/workdata/scour.log This will tell you when mcscour.sh is run from cron (by the file's time stamp), and what it deleted. Tom
