Package: slurm-llnl
Version: 16.05.9-1
Severity: normal


[remark: this might be a problem of systemd, I'm not sure whether this
is an issue of slurm or of systemd.]

When upgrading from debian 9.10 to 9.11 [2], a configuration entry in
 /etc/systemd/system/multi-user.target.wants/slurmd.service
got lost.

In order to address an issue ("Cannot allocate memory" when running mpi
jobs under slurm, it is described in [1]) we had to add in
 /etc/systemd/system/multi-user.target.wants/slurmd.service

this entry

  [Service]
  ...
  LimitMEMLOCK=1000000000000


After upgrading to debian 9.11 [2] this entry configuration disappeared.
It took some time to identify the issue. The fix/workaround is to
manually add the entry in the configuration file again, and run
   systemctl daemon-reload
   systemctl restart slurmd

I'd have expected that the configuration is maintained when doing
  apt update && apt upgrade

Below is the system information from a machine that is not upgraded yet,
and it happens also on machines with Debian 9.10.

Thanks for considering.

This is not a bug in the package: /etc/systemd/system/*.target.wants
directories contain symbolic links to unit files provided by the
packages under the /lib/systemd/system directory. Local units created by
the system administrator should be placed either in
/etc/systemd/system/*.service or in /etc/systemd/system/*.service.d
