tin disk space at 5%
Closed, ResolvedPublic


Tin started sending an alert of low disk space on Icinga (there is still 14G available). I am assigning this to the release engineering team (with ops assistance) to see if some large change on the files there was done recently? In many cases this is logs or any temporary structure and can be easily deleted.

If you do not know, I can log in myself and find what is the main usage, but preferred to notify you first, in case it was something known by you.

If the extra space used was actually needed because of requirement growth, we would need to see how to provide it.

The thing that takes all the space here mostly is /var/lib/l10nupdate/caches is 53G.

This seems familiar, like we had the same issue before, and the question is if we need to keep all these versions around:

@Krenair is also using tin to upload files (~92G) - T111941: Please upload large files to Wikimedia Commons because terbium doesn't have enough space.

I deleted the 46GB original archive, other files will go soon.

Original report of <6% disk space alert is gone. I am retiring operations from the projects (sadly, we do not have a "Done" column), and let tin's users full control of it (close the ticket, delete more files, request more resources, etc.).

Filled in a few other tasks:

T112509: Trebuchet should repack / pack-refs git repos under /srv/deployment
T112508: scap / deployment of branches should get rid of old caches on tin /var/lib/l10nupdate/caches

What about those /tmp/mw-cache-* files?

Deleted the remaining upload files (since that's resolved now) - 106G (42%) free

hashar claimed this task.

If one has any garbage collection ideas, feel free to create subtasks as appropriate.

Since @Krenair cleaned up all disk and we are now at 42% free, I am closing this task.
