I try to checkpoint jobs. But get following errors on my log files, and
the checkpoint files does not been created:
Log of the server:

I have
JobCheckpointDir = /home_palamut1/slurm/checkpoint
CheckpointType = checkpoint/blcr
lines in my slurm.conf file. My job file includes
#SBATCH --checkpoint=1
#SBATCH --checkpoint-dir=/home_palamut1/sefa/checkpoint
mpirun ./count
lines.
Note1: previosly, I was getting an error something like "debug:
checkpoint/blcr: file sbin/scch" since I don't have it. Then I created a
script file which does nothing (just #!/bin/bash). After that I started
to get the above error.
Note2: I am building slurm with " rpmbuild -tb slurm-2.4.1.tar.bz2" and
the srun_cr command wasn't created.

You can checkpoint/restart a job or requeue it (which cancels the
original job). These only work for batch jobs.
Quoting Sefa Arslan<[email protected]>:
I want to migrate a running job from one node to another (or from a
partition to another partititon)
I am using the following commands for this operation:
# scontrol update jobid=100002 partition=best
and get the "slurm_update error: Requested operation is presently disabled"
or
#scontrol update jobid=100002 nodelist=lufer118
and I get "slurm_update error: Invalid node name specified".
What may be the problem of my configuration? How should I change it?
I search on web but I couldn't find much things.
We are using SLRUM-2.4.1 on this test cluster.
The scontrol show config output is:
