Re: [Condor-users] Condor Error No locks available

[lohit <lohit.vijayarenu@xxxxxxxxx>]

Hello Kent,

Thanks for the reply.
- What architecture/OS are you running on?
I am using Ubuntu LINUX (Linux cpu02 2.6.12-10-amd64-xeon #1 SMP Thu Dec 22 11:43:32 UTC 2005 x86_64 GNU/Linux)

- Is this problem repeatable or not?
Yes it is repeated and am not sure how to proceed

- Would it be possible for you to move the node job log files themselves
  off of NFS?  That's probably the first thing to try.
I tried this. I generated the sub file using condor_submit_dag -no_submit command. and then edited the file to point all log, lock files to local disk on node. Yet I am seeing this error. Here is my edited 
run.dag.condor.sub file

# Filename: run.dag.condor.sub
# Generated by condor_submit_dag run.dag
universe        = vanilla
executable      = /home/usr1/condor/bin/condor_dagman
getenv          = True
output          = run.dag.lib.out
error           = run.dag.lib.out
log             = run.dag.dagman.log
remove_kill_sig = SIGUSR1
arguments       = -f -l . -Debug 3 -Lockfile /scratch/usr1/run.dag.lock -Dag run.dag
 -Rescue /scratch/usr1/run.dag.rescue -Condorlog /scratch/usr1/run.dag.dummy_log
environment    = _CONDOR_DAGMAN_LOG=run.dag.dagman.out;_CONDOR_MAX_DAGMAN_LOG=0

A few questions:
- What architecture/OS are you running on?
- Is this problem repeatable or not?
- Would it be possible for you to move the node job log files themselves
  off of NFS?  That's probably the first thing to try.
