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…

Probably nothing then; did you try ./launcher cleanup

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? ncdu shows the below for /var/lib/docker/overlay2 2.2 GiB [##########] /bd441c96567c23eee5ab702c8e96dead0c1f7770d441aefb00e36d5f5dc06ba3 1.9 GiB…

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

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

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