Description

Observation

I copied the corrupted config file to /etc/openqa/openqa.ini.corrupted-2024-07-11-okurz-poo163790

On backup-vm.qe.nue2.suse.org I see:

-rw-r--r-- 1 martchus root 10463 Jun  7 03:32 /home/rsnapshot/gamma.3/openqa.suse.de/etc/openqa/openqa.ini

so judging from the size it seems like 2024-06-28 is the last good. I copied back that config to OSD with

ssh backup-vm.qe.nue2.suse.org "cat /home/rsnapshot/gamma.0/openqa.suse.de/etc/openqa/openqa.ini" | ssh osd "cat - | sudo tee /etc/openqa/openqa.ini"

and restart the openqa-webui service.

Suggestions

  • Enable filesystem checksums (can be enabled for ext4) and check dmesg output in case of corruption
  • Ask around if there might be other options (especially if this has e.g. a big performance hit or version requirements we can't cope with)
  • Read: https://ext4.wiki.kernel.org/index.php/Ext4_Metadata_Checksums
  • Check for any problematic configurations in our salt states

Out of scope

  • Write a filesystem driver

#163592 was resolved. I didn't see the same problem again. I assume if the system is under heavy load then if salt is called files become corrupted. I am researching if this is known elsewhere.

I asked in #discuss-salt https://suse.slack.com/archives/C02JMF41G9E/p1722002950510019

hi, anyone ever had the case that salt would incompletely write managed files? We have observed already two times that in files either content is missing or invalid, non-ASCII characters are included in files managed by salt or changed by salt.

No response as of now. In the meantime learning https://docs.saltproject.io/salt/user-guide/en/latest/

I would like to work on #164427 first because I assume there is a chance that files are corrupted or incompletely written if the system is stalled due to #164427
