[workspace-user] Propagation with gsiftp failing - library loading error

[Duncan Penfold-Brown]

Hi,

I am running into a problem in trying to use gsiftp propagation with my 
Workspaces system. To test propagation, I have images on my services 
head-node that are to be pulled down to the hypervisor node for booting. 
After properly setting all config files, I get an error in the 
workspace-control create log for the workspace I try to propagate and 
create.

Upon executing the workspace command from the services node, output 
looks normal. The deployment stages and workspace information are 
printed out as expected, and finish with the deployment message 
"Changing state: Unpropagated --> Running." This appears normal, and is 
consistent with previous working tests. All output to the container.log 
file is also normal and expected, with the ssh call to the hypervisor 
node returning successfully.

However, the workspace is not created on the hypervisor node. Looking in 
the workspace create log, I get this error message from globus-url-copy:

2007-03-22 15:01:53,343 - DEBUG - workspace.xen_v2 (541) - image is

/usr/local/globus-4/bin/globus-url-copy: error while loading shared 
libraries: libglobus_gass_copy_gcc32.so.0: cannot open shared object 
file: No such file or directory


This is a familiar error, and has occurred before due to unset 
environment variables that globus-url-copy requires to find files. 
However, all globus env. variables are set correctly (under all 
applicable accounts, namely globus, and root for good measure). 
Furthermore, when I copied that exact command from the log and executed 
it from the globus account, it worked perfectly.

So, in short: I don't know why globus-url-copy is having problems 
finding the above library when called by workspace-control, as otherwise 
globus-url-copy works fine. Any help is appreciated.


PS: I do have valid certificates and proxies on both the services and 
hypervisor nodes. Also, the globus directory on the hypervisor node is 
NFS'ed, if that somehow could make a difference. Also, I have 
successfully tested propagation with scp, and found it to work without 
issues.


thanks,
