[gridsam-discuss] GridSAM file staging errors

[Stefan Z. <ste...@uc...>]

Hi,

We have GridSAM instances setup to submit jobs to the UK NGS via the  
Globus GRAM 2 connector. When running our jobs, we use GridSAM to  
stage input and output data from a WebDav server to the GridFTP server  
running on the NGS node we are using. While there are no problems  
staging files from our WebDav server to the NGS, when we stage data  
back we see that some of the files have been mangled. All files staged  
back to the WebDav server after the job completes are of different  
sizes and have different MD5 signatures to the original versions on  
the NGS node, for example:

NGS
[ngs0009@vidar 154382481094266025861]$ md5sum fbpc-1-a-3.out.dcd
ba25432f11942ab81d325796dbfc7003  fbpc-1-a-3.out.dcd

Local machine
nak 585 $ md5 fbpc-1-a-3.out.dcd
MD5 (fbpc-1-a-3.out.dcd) = f6ecc06a87df9cd559519de4ea467bbc


Has anyone come across this problem before? We are using GridSAM with  
OMII container

Any help resolving this would be much appreciated.

Thanks,

Stefan.
