It looks like you have something on your network with an older version of slurm installed. I'd check the Slurm version installed on your compute nodes and controllers.

The recommended approach to upgrading is to upgrade the SlurmDB first, then the controllers, then the compute nodes. More info here:

Hi,

I am attempting to upgrade from SLURM 18 to 20.11.9 and when I attempt to start slurmdbd (version 20.11.9), I get the following error messages in /var/log/slurm/slurmdbd.log:

[2022-09-08T15:45:11.115] slurmdbd version 20.11.9 started
[2022-09-08T15:45:23.001] error: unpack_header: protocol_version 8448 not supported

[2022-09-08T15:33:57.011] error: CONN:11 Failed to unpack SLURM_PERSIST_INIT message

Any help will be greatly appreciated.
