This is a common problem. I run to this almost weekly basis doing a lot yocto compiles on my developer machine. Solution for me is to manually check before compiling that I still have 100's gigabytes of diskspace free. If not, I will delete first build/tmp directories. If that doesn't give me enough free space, I sometimes need to delete the whole build directory which includes the sstate cache directories. In worst case I need to delete also the download cache directories which in my case lives outside of build directories. On CI build servers I start every build by cleaning the build directory but I do preserve the sstate cache, cache directory (prserv database from previous release), and download cache. Size of the caches on each CI server is monitored separately. Hope this helps, -Mikko
