[Condor-users] Re : Dagman job cannot start second node

[Vigilant Lionel <vigilantl@xxxxxxxx>]

Hi Kent,

First answer, un.log on a shared through nfs (user's home directory)

 
I tried with ENABLE_USERLOG_LOCKING = FALSE, but right after submiting the first node (which stay in idle state) ... dagman is killed by signal 11. I suppose that's the bug you talked about ...
So I placed the log file in /tmp and it worked.
Waiting for 7.0.4 to use with nfs

Thanks a lot

I want to use dag jobs so i tested with two simple Cpp progs :

un submit file :
Universe = standard
Executable = un
Log = un.log
Output = un.out
Error = un.err
Arguments = 35
Queue

Okay, my first question is whether un.log is on a shared filesystem.  If
so, is it possible to move it to a place that's on a local disk on your
submit machine?

You *should* also be able to work around this (somewhat dangerously) by
setting ENABLE_USERLOG_LOCKING to false in your configuration, but we just
found a bug with that, which is probably in 7.0.1 (it's known to be in
7.0.2).  The fix should be in 7.0.4.
