/var/lib/docker/overlay2 disk usage Very High

Product Support Self-hosting

AI-generated summary

The discussion revolves around the high disk usage of /var/lib/docker/overlay2 on a 40GB VPS, which currently stands at 15.1GB. adambirds suspects it might be due to running ./launcher rebuild app earlier. codinghorror mentions that the recent addition of retina image thumbnails might increase disk space usage, but adambirds thinks the 3GB rise in a day is unusual.

codinghorror suggests running ./launcher cleanup to reclaim disk space. adambirds is unsure if it’s safe to run on an active site, but codinghorror assures it’s extremely safe. After running the command, adambirds reports that 3.45GB of disk space was reclaimed, likely due to the build caches.

I have a new forum, which currently has around 60 users, and currently only about 3 topics. (I only invited users today). We hope to have around 3000 users.

I have a 40GB VPS currently, which can be expanded, but /var/lib/docker/overlay2 is around 15.1GB in size and seems to have increased by a few GB just today which doesn’t seem normal.

Wondering if it due to having run ./launcher rebuild app earlier to fix the issue with the profile pictures.

Is their a way to clear these down, I presume they are docker volumes that got duplicated when running the rebuild.

We recently added retina image thumbnails in 2.2 which will increase the disk space usage a fair bit particularly on forums that post a lot of images.

That shouldn’t have caused a 3GB rise in a day though should it when there has only been 3 topics and 6 replies?

Could it have been the rebuild?

Probably nothing then; did you try ./launcher cleanup

5

No. I didn’t know that was a thing. Is that fine to run on an active site without it breaking anything? @codinghorror

Thanks

6

Yes this is all extremely safe

7

Excellent, thanks, that reclaimed 3.45GB so must have been the build caches. @codinghorror
