Hello,
is there anyone using plain Debian with Slurm (as provided by the OS
repository),
who might have suggestions for our upgrade from Buster to Bullseye?
Of course we'd like to keep the database (user definitions and job history), but
We're now running version 18.08.5.2 (Buster's version) while Bullseye comes with
20.11.x, which is beyond the 2-version upgrade range. Is there hope (and how to
verify that) that a dist-upgrade would do the right thing?
Thanks,
Steffen
Hello,
I've done an upgrade from Debian 7 (slurm 2.3.4) to Debian 8 (slurm
14.03.9). I've prepared the upgrade with a small setup in virtualbox and
experienced the fact that dist-upgrade failed.
The actual upgrade process of the front node was:
- stop slurm and backup the data (/var/lib/slurm and the mysql database)
- uninstall slurm
- do the debian upgrade
- download and compile an intermediary version (2.4.5)
- start slurmdbd and wait for the mysql database to be updated
- start slurmctld and wait for the data in /var/lib/slurm to be updated
- redo the same for another intermediary version (2.6.9)
- finally install slurm from Debian 8 (14.03.9)
- check that all the user data and job history are preserved
(sacctmgr, sacct, sreport)
Preparing the upgrade procedure on an experimental setup was time
consuming but rewarding.
