Hi Paulo,
Maybe what you see is due to a bug then? You might try to update Slurm
to see if has been fixed.
You should not use the Slurm RPMs from EPEL - I think offering these
RPMs was a mistake.
Anyway you ought to upgrade to the latest Slurm 23.02.6 since a serious
security issue was fixed a couple of weeks ago. Older Slurm versions
are all affected! Perhaps this Wiki guide can help you upgrade to the
latest RPM: https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_installation/

Yes, the script is running and changing other fields like comment, partition,
account is working fine. The only problem seems to be the script field of
job_rec. I'm using Slurm 20.11.9 from EPEL repository for RHEL 8. Thank you for
sharing your Wiki. I've accessed it before. It's really useful for HPC
engineers.
Best regards,

job_submit.lua plugin
Hi Paulo,
Which Slurm version do you have, and did you set this in slurm.conf:
JobSubmitPlugins=lua ?
Perhaps you may find some useful information in this Wiki page:

Is it possible to change something in user’s sbatch script by using a
job_submit plugin? To be more specific, using Lua job_submit plugin.
I’m trying to do the following in job_submit.lua when a user changes
job’s partition to “cloud” partition, but the script got executed
without modification.
function slurm_job_modify(job_desc, job_rec, part_list, modify_uid)
if job_desc.partition == "cloud" then
slurm.log_info("slurm_job_modify: Bursting job %u
from uid %u to the cloud...",job_rec.job_id,modify_uid)
script = job_rec.script
slurm.log_info("Script BEFORE change: %s",script)
-- changing user command to another command
script = string.gsub(script,"local command","cloud
command")
slurm.log_info("Script AFTER change %s",script)
-- The script variable is really changed
job_rec.script = script
slurm.log_info("Job RECORD SCRIPT %s",job_rec.script)
-- The job record also got changed, but the EXECUTED
script isn’t changed at all. It runs without modification.
end
return slurm.SUCCESS
end
