by Steve Kirk 11 Aug '25

Hi, Am I correct in thinking that the history of a *node* as shown by sinfo isn't stored anywhere by Slurm? Interested to know if slurm can tell me historically when a node was draining,drained etc. Regards, Steve

Building Debian packages - problem
by John Hearns 05 Aug '25

05 Aug '25

I am trying to build Slurm version 24.11.6 on an Ubuntu 22.04 system. I download and unpack the source mk-build-deps -i debian/control (not run as root) debuild -b -uc -us I get this error repeated many times: dpkg-shlibdeps: warning: can't extract name and version from library name 'libslurmfull.so' Has anyone seen similar issues? For information, there is an existing SLurm installation on this syste, with version 21 dpkgs from the Ubuntu repository.
