Acceptance Criteria

  • AC1: Worker31 boots reliably without any issues mounting disks

Rollback steps

  • hostname=worker31.oqa.prg2.suse.org ssh osd "sudo salt-key -y -a $hostname && sudo salt --state-output=changes $hostname state.apply"
  • ssh osd "worker31.oqa.prg2.suse.org' cmd.run 'systemctl unmask rebootmgr && systemctl enable --now rebootmgr && rebootmgrctl reboot'"

Suggestions

  • Login and check failed services
  • Restart services and/ or the worker
  • See #162293#note-30 for recent changes to the disk array setup

Let's see if a straightforward restart may do the trick, or if this is more involved.

I can't seem to login on Grafana even after triple-checking the login I was using. Same with stats. so it wouldn't seem like the old issue with the other domain.
Hence alert not silenced for now.

I guess it's not just the race condition and multiple reboots did not help. Maybe best to estimate first.

There is no proper raid config because openqa-establish-nvme-setup fails:

Creating RAID0 "/dev/md/openqa" on: /dev/nvme1n1 /dev/nvme2n1
mdadm --create /dev/md/openqa --level=0 --force --assume-clean --raid-devices=2 --run /dev/nvme1n1 /dev/nvme2n1
mdadm: cannot open /dev/nvme1n1: Device or resource busy

It seems that a broken mdraid config was present on /dev/nvme1n1 that prevented creating a new raid.
I unloaded the md_mod kernel module and wrote 10MB of zeros to the nvme1n1 device, then loaded md_mod again.

Afterwards openqa-establish-nvme-setup was able to run fine.

But after a reboot, the problem comes up again.

  • Status changed from In Progress to Resolved

After the reboot mdadm --examine /dev/nvme2n1 didn't show any traces of a raid on nvme2n1.
Also no traces of raid name at offset 0x1020 in dd if=/dev/nvme2n1 bs=1k count=10 | hexdump -C.
Stopped the inactive raid on nvme1n1 via mdadm --stop /dev/md127.

dd if=/dev/zero of=/dev/nvme1n1 bs=10M count=1
dd if=/dev/zero of=/dev/nvme2n1 bs=10M count=1

Then openqa-establish-nvme-setup worked and the machine even survived a reboot.

Due to the fact that SMART reports that both nvme1n1 and nvme2n1 are way above the vendor supported written bytes (137% and 133%) and smartctl -H /dev/nvme1n1 (also for 2n1) reports:

=== START OF SMART DATA SECTION ===
SMART overall-health self-assessment test result: FAILED!
- NVM subsystem reliability has been degraded

... I would expect this to only be working by chance - the NVMEs being broken and being unreliable or breaking in the near future, until we replace them.
