open[alert] Root partition on OSD was almost completely full
0%
Description
Observation¶
The root partition on OSD was almost completely full from 2025-03-28 07:29:19 to 2025-03-28 07:40:50. It went back to normal. We should investigate what happened. Considering the usage is back to only 60 % there's probably no need for cleanup right now.

shows multiple short-time spikes. We should take a look if users log in and copy around assets. If they do yell at them!

Another spike in this time range: https://monitor.qa.suse.de/d/WebuiDb/webui-summary?orgId=1&viewPanel=panel-74&from=2025-03-28T09%3A37%3A26.702Z&to=2025-03-28T09%3A39%3A47.133Z&timezone=utc&var-host_disks=%24__all
It was only a short spike so I wasn't quick enough with ncdu.
Note that we have 7.3G headroom (in absolute numbers).
The audit log is less than 50 MiB in total so that's probably not it.
User homes are not on the root partition so that's probably also not it.

It has just resolved itself:
martchus@openqa:~> df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 20G 11G 7.4G 60% /
The check with ncdu still looks the same, though:
--- / -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
5.7 GiB [##############################] /usr
4.0 GiB [##################### ] /var

I also see no difference on nested levels.
Note that I used ncdu -x / to avoid checking across file systems. The ncdu run mentioned on #179629#note-9 was definitely performed while df showed the following from start to end:
df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 20G 18G 727M 97% /
I actually ran ncdu multiple times while df -h was showing that with consistent results.

- Status changed from In Progress to Feedback
- Priority changed from Urgent to High
This wasn't urgent as of late Friday, right?
I suggest we ask for an increase of the root partition 20G->40G and see if we still have problems with spikes
We probably don't want to compromise on audit logs if those consume more space. So a just need an SD ticket here.

We did had another spike (https://monitor.qa.suse.de/d/WebuiDb/webui-summary?orgId=1&from=2025-03-29T11%3A27%3A41.155Z&to=2025-03-29T12%3A03%3A57.831Z&timezone=utc&var-host_disks=%24__all&viewPanel=panel-74) so I'm creating an SD ticket.

SD ticket: https://sd.suse.com/servicedesk/customer/portal/1/SD-184246
When /dev/vda has been increased when cannot just increase /dev/vda1 without first removing /dev/vda2.
