[slurm-users] Plugins failing on Slurm v22 build Rocky Linux 9

[Mark Holliman]

Ole,

Thanks for replying. I installed a fresh version of RockyLinux 9.1. I mentioned Fedora 9 and CentOS 9 (Stream) simply because they tend to be compatible, and something that works on them is likely to work on Rocky9.

I am building the RPMs from tarball, following instructions near identical to those you link (the ones on the Slurm website). I originally followed them exactly, which resulted in an install with the error I posted below. Searching online for that error led me to the suggested fix of turning off the system hardening and rebuilding/reinstalling, but this didn't solve the problem either.

I turned up debugging and went through my config line by line and found the offending plugin is set at: JobAcctGatherType=proctrack/linuxproc
I've replaced this with: JobAcctGatherType=jobacct_gather/linux and now the system starts. I suppose the old plugin is no longer/used supported and I missed it in the docs somewhere.

Thanks!

Cheers,
  Mark

Hi Mark,

Did you upgrade to the RockyLinux 9.1 which has just come out?  Why do you talk about Fedora 9 (now we have Fedora 37) and CentOS 9 (non-existent)?

Have you tried building Slurm RPM packages from the tar-ball?  Check out https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_installation/#build-slurm-rpms
After installing prerequisites, the command is simply:
$ rpmbuild -ta slurm-$VER.tar.bz2 --with mysql

If this fails, someone would have to submit a bug report against EL9 to SchedMD.

Personal opinion: I would not recommend Slurm packages from EPEL.

/Ole
