[Condor-users] Checkpoint server installation problem.

Subject: [Condor-users] Checkpoint server installation problem.

Hi. Genie again.

I feel sorry about day after day questions.

Now, it's about checkpoint server.

I read through the page, http://www.cs.wisc.edu/condor/manual/v7.4/3_8Checkpoint_Server.html, to learn how to install it.

And I'm stuck with the line below. I don't know what the second line means.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Described in section 3.3.9. To have the checkpoint server managed by the condor_master, the DAEMON_LIST variable's value must list both MASTER and CKPT_SERVER.

Also add STARTD to allow jobs to run on the checkpoint server machine. Similarly, add SCHEDD to permit the submission of jobs from the checkpoint server machine.

I did add the lines below to the condor_config file in all our machines.

DAEMON_LIST = MASTER, STARTD, SCHEDD, CKPT_SERVER

CKPT_SERVER = $(SBIN)/condor_ckpt_server

USE_CKPT_SERVER = True
CKPT_SERVER_HOST = 192.168.0.109

and the file, condor_config.local, in the 192.168.0.109

CKPT_SERVER_DIR             = /data/ckpt_server
CKPT_SERVER_LOG           = $(LOG)/CkptServerLog
MAX_CKPT_SERVER_LOG   = 1000000
CKPT_SERVER_DEBUG      = D_ALWAYS
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Then, my MasterLog file says

01/25 17:47:50 Started process "/condor/sbin/condor_ckpt_server", pid and pgroup = 9895

and CkptServerLog file says

And there's no file in /data/ckpt_server directory, even though condor has it and in 755 permission.

What I did wrong?

Thanks for reading this long mail.
