Re: [Condor-users] Standard Universe Jobs - File Permission Errors

[Paul Browne <pb337@xxxxxxxxxxxxxxxx>]

Hi,

Thanks for replying.

These are all Linux nodes, all running Condor.x86_64.7.8.1.rhel4 on Scientific Linux.

The problem is that Vanilla Universe jobs running on a different execute machine than submit machine can't write to a network mounted directory, despite this directory being present in the same place on all machines. It must be a permissions issue of some kind, but I can't work it out.

Regards,

Paul Browne

Are your nodes running Linux or Windows?

Apologies, I am referring to network problems running Vanilla universe
jobs, not Standard universe.

Standard universe jobs run fine, but can't be used for our needs.

We have a small Condor 7.8.1 x86_64 pool of one central manager
(also a submit & execute machine) & two submit/execute machines.

When a standard universe job is submitted from one machine that
requires I/O access to directories which are NFS mounted in the same
place on each machine, the jobs will not run or produce output due
to file permission errors.

So a job submitted on one machine will only run on the machine it
was submitted from, & will not run on any other machine. I have
tried to read the admin manual about how to resolve this issue
without making network mounted directories world-writeable (which
would certainly work), but haven't made progress.

Might anyone have ideas about how our pool configuration might be
resolved to allow Condor jobs which are submitted from one machine
to execute on another machine, when they need I/O access to
directories which have been NFS mounted in the same places on all
machines in the pool?

This is a major problem, reducing our capability for time-sensitive
computations by (at present) a full two thirds, so any help would be
very, very welcome.

Kind regards,
Paul Browne
