[slurm-users] Upgrading SLURM from 18 to 20.11.9

[Wadud Miah]

hi Mick,

I have checked that all the compute nodes and controllers all have the same version of SLURM (20.11.9). I am indeed trying to upgrade SlurmDB first, and am getting the errors in the 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
[2022-09-08T15:33:57.001] unpacking header
[2022-09-08T15:33:57.001] error: destroy_forward: no init
[2022-09-08T15:33:57.001] error: slurm_unpack_received_msg: Message receive failure
[2022-09-08T15:33:57.011] error: CONN:11 Failed to unpack SLURM_PERSIST_INIT message

Regards,
Wadud.

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:

Any help will be greatly appreciated.
