Description

In https://infra.nue.suse.com/SelfService/Display.html?id=178140 we asked SUSE IT to give us more storage in particular linked to the need for SLE4SAP+HA. gschlotter did that, we learned that vdc (/assets) is actually on cheap+slow storage (rotating disk).

Did xfs_growfs /assets now which gave us 7TB for /assets with a current usage. Can adjust job group quotas and will monitor at best over next weeks how the usage turns out.

ok. I walked over all non-development, non-released job groups I could find on osd and rounded up the quota limits as well as gave some groups more space which I think could make good use of it. I will monitor the situation over the next time, e.g. reviewing the latest at the due date and see if we need or can or should to adapt again.

So in https://infra.nue.suse.com/SelfService/Display.html?id=178140 we came to the agreement that it is easier and better to keep both vdc+vde even if both are on "cheap+slow" storage.

I have added corresponding comments in /etc/fstab now, complete file content:

I asked gschlotter for more space on /space-slow as well and have extended the file system:

current df situation:

/dev/vda1       9.6G  6.3G  2.9G  69% /
/dev/vdb         80G   51G   30G  64% /srv
/dev/vdc        7.0T  3.8T  3.3T  53% /assets
/dev/vdd        5.0T  3.7T  1.4T  74% /results
/dev/vde        3.0T  1.6T  1.5T  53% /space-slow

This means that likely we will not have a problem with "assets" very soon, "results" are more likely to pose a problem.
