No logging info from DSI

[bnordgren]

I built the DSI against irods 4.2.0 on centos 7 (see Docker build env). I believe this container to be set up to log to /var/log/gridftp.log at the INFO logging level. I have also tried the "ALL" logging level, with no difference.

I'm attempting a directory listing of my home directory with globus-url-copy. It fails. But all that is logged to /var/log/gridftp.log is:

[6] Sat Dec 23 19:04:47 2017 :: Child process 21 ended with rc = 11

This ticket isn't so much about my actual error as it is about the fact that no useful information is logged even at the "ALL" level.

Note you can't directly run a container from an image generated from the docker build above. The intent is that you use the image above in the FROM line of an environment-specific Dockerfile, where you make the irods service account authenticate as the rods user in your zone, and perform other configurations specific to your deployment. However, the above build environment has everything related to this ticket.

Any log on the client side?

Unfortunately, if the DSI crashes for any cause, the logs are not flushed to the stdout.

Hi @bnordgren : I was also at times experiencing similar problems with nothing logged.

I think this tends to happen when the dlopen of the iRODS DSI fails. With iRODS 4.x, the DSI shared-object has dependencies on the iRODS libraries ... and my only way around it was to LD_PRELOAD these dependencies into the GridFTP server (that's now in the documentation).

I'd suggest you check the LD_PRELOAD is there and is working correctly...

Cheers, Vlad

Hi @vladimir-mencl-eresearch , The problem was indeed the lack of an LD_PRELOAD. Thanks! Previously, I omitted it on purpose because the docs specify that LD_PRELOAD is required for 4.1 and I was building against 4.2.

@muccix The globus-url-copy program outputs the following (when broken):

My specific problem is fixed, but I'll leave this open due to the topic being the lack of logging output.
