Re: [Condor-users] mixed pool: NFS and non-NFS directories

I am running OSG on a small (20 node) Condor pool with NFS and shared home directories for VOs. I am interested in finding out if it is possible and practical to add into the pool other execute nodes which don't have shared NFS or user home directories. Can anyone offer any tips or suggestions regarding this?

Condor is happy to run without a shared filesystem. If a user doesn't request file transfers for a job but, it is assumed that the files are on a shared filesystem. Condor detects if you share a filesystem by looking at FILESYSTEM_DOMAIN. Details are in the manual: I can point you to specifics if you need them. If a user specifics that files should be transferred "if needed", then FILESYSTEM_DOMAIN is used to decide if you are on the shared filesystem, or if the files need to be transmitted.

Out of the box, the OSG Globus installation assumes that Condor is using a shared filesystem, and when it submits jobs to Condor it doesn't tell Condor to transfer files. There is an alternate Condor job manager that does tell Condor to transfer files. Some VDT-specific documentation is at:

I don't think it is a documented solution in OSG, but several sites are using it with success. You'll need to install it from the VDT cache instead of the OSG cache.
