Description
Observation¶
We got an alerting email on 2021-04-25 openqaworker8: host up alert
Connected to that machine using ipmitool -I lanplus -C 3 -H openqaworker8-ipmi.suse.de sol activate, the content showed that:
[SOL Session operational. Use ~? for help]
Login incorrect
Give root password for maintenance
(or press Control-D to continue):
Then pressed Control-D, the machine started to boot.
Acceptance criteria¶
- AC1: The machine reboot successfully
Updated by okurz over 3 years ago
- Priority changed from Normal to High
- Target version set to Ready
Updated by livdywan over 3 years ago
- Status changed from New to Feedback

I bet this was only caused by the RAID/NVMe setup as the corresponding systemd unit failed at that time, see journalctl --since '10 days ago' -u openqa_nvme_format.service:

I assume that all logs are still on the system from the date of ticket creation. Or do you see something missing?

Raid 0 with only one device ( I know, RAID0 is only performance optimization but still)

Good observation but no worries, this is by intention. Within https://gitlab.suse.de/openqa/salt-states-openqa we came up with recipes for using [0..N] NVMe devices for openQA use all with the same setup. In some cases for some machines we have 0 NVMe devices, in some 1, in some other 2 devices. This ensures a simple, consistent setup for all cases and also automatic fallback in case any of the NVMe devices fail (as happened in the past) as the worker machines can still run with a reduced set of devices just in degraded fashion.

maybe we can add --assume-clean to mdadm command ?
Updated by okurz over 3 years ago
a very good idea. Can you add that in https://gitlab.suse.de/openqa/salt-states-openqa ? To try it out e.g. on openqaworker8 I suggest you do systemctl disable --now salt-minion telegraf && systemctl mask salt-minion telegraf, adapt the files manually (I think in /etc/systemd/system/…) and reboot

@mkittler @osukup MR https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/486 merged and in deployment right now. Do you think the mentioned change does fix the issue that caused the reboot alert or is this side-fix?

No, but in general it can take quite a while until a ticket is picked up and then the logs might be gone.
Do you think the mentioned change does fix the issue that caused the reboot alert or is this side-fix?
Maybe it fixed it. I suppose the boot was really prevented by the RAID/NVMe setup. Whether adding --assume-clean helps is of course a different story. Considering we've got the log message mdadm: /dev/nvme0n1p3 appears to contain an ext2fs file system it might help. The final error message mdadm: unexpected failure opening /dev/md127 is unfortunately quite unspecific.

agree, I see this more like workaround -- the question is why mdadm saw ext2 fs on the device ...

maybe it's trying to be "too smart" :D
