hey,

so I can understand both of your sides - and yeah, one can probably argue if this is "Administration of workers" or "maintenance of workers".
but since this is lying around for such a long time, it seems that apparently the annoyance of this not being done is not high enough (yet).

I don't see a crystal-clear responsibility for that task here, so what about the following proposal:
do a joint collaboration between QSF and Tools team - sit down for few hours and do this thing together? I'm happy to help here of course =)

Yes, I think so. This is why I lowered from "High" to "Normal" priority.

Well of course everybody is happy to offer help but this task lying around for more than a year already shows that this is not problem. Just an outlook into the future if nothing is done here: Eventually the machines will break down or need to be replaced (again) and everybody will just point to mgriessmeier who should know best ;)

Well, if SUSE QE Tools needs to maintain these machines then we should aim to migrate to openSUSE Leap 15.3 anyway

• s390zl12.oqa.prg2.suse.org and s390zl13.oqa.prg2.suse.org are both running openSUSE Leap 15.5

There are some steps necessary to set up before it can be used to execute s390x KVM jobs.

• Packages that need to be present:
  • multipath-tools
  • libvirt
• directories
  • /var/lib/openqa/share/factory
  • /var/lib/libvirt/images
• services
  • libvirtd
  • multipathd
• ZFCP disk for storing images
  • cio_ignore -r [fc00,fa00] to whitelist the channels
  • zfcp_host_configure [fa00,fc00] 1 to permanently enable the fcp devices
  • multipath -ll to check what devices are there
  • /usr/bin/rescan-iscsi-bus.sh to discover newly add ed zfcp disks
  • fdisk to create new partition
  • mkfs.ext4 to create file system
• /etc/fstab entries
  • NFS openQA: openqa.suse.de:/var/lib/openqa/share/factory /var/lib/openqa/share/factory nfs ro 0 0
  • ZFCP disk: /dev/mapper/$ID /var/lib/libvirt/images ext4 nobarrier,data=writeback 1
• crontab -e
  • 0 */1 * * * /usr/local/bin/cleanup-openqa-assets >/dev/null

~# cat /usr/local/bin/cleanup-openqa-assets
#!/bin/sh -e
echo "--- cronjob start ---"
if [[ $(df | grep "/var/lib/libvirt/images" | awk '{print $5}' | sed "s/\%//") -gt 70 ]] ; then
    echo "--- entering if ---"; 
    find /var/lib/libvirt/images/*.qcow2 ! -exec fuser -s "{}" 2>/dev/null \; -exec rm -f {} \; -print
fi
echo "--- cronjob end ---"

Ok, let's start somewhere: https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/1010

I included installation instructions from #51836-15 in https://progress.opensuse.org/projects/openqav3/wiki/Wiki#s390-LPAR-setup for things that are not feasible or not possible to do via salt but need to be done during installation.
