For Qlustar 12.0 and 13

nvidia-graphics-drivers                      535.54.03-ql.1
qlustar-module-nvidia-jammy-amd64-13.0       13.0.5-b565f1497

qlustar-module-nvidia-centos7-amd64-12.0.2   12.0.2.5-b566f1498

Special Update instructions:

In addition to the steps described in the general Qlustar Update Instructions these updates require the following:

• On Qlustar 12, also perform the following manual steps if you haven’t done so yet: Write the dnsmasq and slurm config with QluMan before rebooting. If your cluster was installed with a release earlier than 12.0.0.8-b546f1425 you will have to generate new LDAP certificates at some point since the earlier ones were generated with a 1 year validity. Now they are generated with an unlimited validity. To check the expiration date execute

  # openssl x509 -dates -in /etc/ssl/certs/qlustar-ca-cert.pem | grep notAfter
  

  To regenerate the certificate with unlimited validity execute

  # qluman-ldap-cli --update-certs
  

  before rebooting the whole cluster.
  Please note that we no longer provide 12.x AlmaLinux 8 modules for Qlustar 12. If you want to use AlmaLinux 8 under Qlustar 12, please switch to the 13.x image modules and create a corresponding chroot for it.
