l2gen cannot write to NFS share?

[7yl4r]

I have observed that l2gen throws a permissions error when trying to write to a location on my NFS share, despite having adequate permissions:

```
INFO - -E- /opt/ocssw/bin/l2gen: Error opening /srv/imars-objects/airflow_tmp/proc_myd01_to_myd0_otis_l2_gom_20180112T065000_l2 for writing.
INFO - Command exited with return code 1
```

The file is accessible for writing, in fact l2gen creates it early at the start of the run but the file never grows beyond 331B.

```
$ ls -lh /srv/imars-objects/airflow_tmp/proc_myd01_to_myd0_otis_l2_gom_20180112T065000_l2
-rw-r--r-- 1 airflow airflow 331 May 23 17:33 /srv/imars-objects/airflow_tmp/proc_myd01_to_myd0_otis_l2_gom_20180112T065000_l2
```

I wonder if this is due to the error detailed in the line just above the error you mentioned?
-E- /home/seadas/ocssw/src/l2gen/l2_generic.c line 437: product opp_cbpm2 not found.

Uh... yes. Yes that was exactly it. Thank you! Somehow I completely missed that line and jumped right to the NFS conclusion. :eek:
