Description
Observation¶
login to aarch64.o.o fails with ssh keys and password, also not working over IPMI SoL. Was reported by mkittler and reproduced by ggardet_arm
Acceptance criteria¶
- AC1: login works again for QE Tools members
- AC2: login works for ggardet_arm
- AC3: We understood how it came to that, e.g. if we have been hacked, system corruption, user error, etc.
Suggestions¶
- If you do not yet have IPMI aliases I suggest https://gitlab.suse.de/openqa/salt-pillars-openqa#get-ipmi-definition-aliases
- Connect over IPMI SoL
- try to boot previous snapshots
- If they don't work boot with
init=/bin/bashor a rescue system or installer if that is available over PXE, and chroot into the installed system - investigate, recover, fix

With IPMI I checked the graphical console and on tty10 (I think) rsyslog was spamming write error: Read-only file system.
I triggered a reboot, as it was inaccessible anyway.

It's up again, apparently running fine.
At "2020-11-12T03:38:14.930211+01:00", logging stopped, probably due to /var becoming read only or whatever the root cause was.

there is also https://infra.nue.suse.com/SelfService/Display.html?id=179857 which I created. We should coordinate with EngInfra.

Machine was shut of now. I started it again, currently booting
Updated by nicksinger over 3 years ago
After I did an explicit "power on" the machine came back online and I was able to login with the expected credentials. As @favogt mentioned (thanks for checking!) errors about /var I fired up smart to see if any errors where reported in the past:

Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
So as you can see the last 21 self-tests where successful without errors. I will dig a little bit more if I can find the root cause but for now the main issue (nobody can login) is resolved.

@nicksinger thanks for taking the ticket . fvogt and guillaume_g are following, discussing about it in irc://chat.freenode.net/opensuse-factory but too shy to update you :D But of course they are happy that you fixed it :)
I updated
https://infra.nue.suse.com/SelfService/Display.html?id=179857
and asked to close it.

Closing for now as it is really hard to debug and the disk itself looks good. All files in /var/log are (obviously) truncated. If this happens again soon and we need to debug further we could think about setting up a central rsyslogd-server (e.g. on o3 itself) to collect the root cause there. I skipped this for now as it would require close monitoring (to not fill up o3 with all the worker logs) and I'm not up for this over the weekend :)
