[slurm-users] Upgrading SLURM from 18 to 20.11.9

[Wadud Miah]

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
[2022-09-08T15:33:57.001] 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

Any help will be greatly appreciated.
