Re: [Condor-users] Is it possible to install Condor without root on an NFS mounted /home/dawn/ directory shared by all executing nodes?

[dawnsong <dawnsong.tsinghua@xxxxxxxxx>]

Anyone has any experience with this?

Any hint is appreciated.

I already googled many webs, and found only one similar problem mentioned in 2004 and the answer was not clear either.

I forgot to mention that I downloaded Condor 7.2.4.

And I tried but failed.

For central manager, condor_status always complains that CONDOR_STATUS:1:Unable to resolve COLLECTOR_HOST (nodeMgr) while condor_master did not report any error.

I found two options in global configuration file and set them (NO_DNS=True, DEFAULT_DOMAIN_NAME = linglj), I didn't know if this would help or I didn't catch its real meaning.

Thanks

Another question, the cluster I want to install condor didn't config any domain/DNS although all the nodes share same /etc/passwd and /etc/group, so I have to levae UID_DOMAIN to blank which is required to start Condor.

How do I overcome this problem?

Hi Condor experts,

I wonder if it is possible to install Condor without root on an NFS mounted  /home/dawn/ directory shared by all executing nodes.

The cluster I could use is a central manager plus some job-executing nodes. All the machines share a NFS home directory. I extracted Condor under my user directory /home/dawn/software/x86_64. So all the nodes share a same Condor executable programs.

After run condor_install (./condor_install --local-dir=/home/dawn/var/condor/`uname -m`/`uname -n`/ --type=manager,submit) on the central manager machine, there would be condor.sh file generated. 

I wonder if I copy condor.sh to condor_node1.sh condor_node2.sh ..., and change the environment variable in this script from

CONDOR_CONFIG=/home/dawn/software/condor/x86_64/condor-7.2.4/etc/condor_config

to

CONDOR_CONFIG=/home/dawn/software/condor/x86_64/condor-7.2.4/etc/condor_config_node1

CONDOR_CONFIG=/home/dawn/software/condor/x86_64/condor-7.2.4/etc/condor_config_node2

...

, then if I start Condor on each nodes, would Condor run successfully?

Or would there be some other options I missed? (I currently didn't consider security problem because only I use condor on this special cluster. )

I think condor very good because I used it for couple of months on my own servers and it didn't even give a error after thousands of submitted jobs. 

Thanks in advance.
