I'm getting enospc errors on a 4GB test device after a while of running. Part of the issue is that many tests can't or don't clean up previous failed runs when they start or if the run to success. Hence while we want to slowly age the test filesystem, we don't really want that aging to unintentionally run the filesystem out of space. To that end: $ sudo du -s /mnt/test/* | sort -nr |head -10 1929160 /mnt/test/fsfile 512000 /mnt/test/247.8133 512000 /mnt/test/247.4713 512000 /mnt/test/247.4488 466752 /mnt/test/fstest.9850.2 40000 /mnt/test/resv 29804 /mnt/test/fsstress.12144.1 26208 /mnt/test/populate_root 26208 /mnt/test/mnt 23216 /mnt/test/fsstress.4491.1 We can see that there are a few tests that using most of the space. These are often left behind due to kernel failures during tests or reboots while tests are in progress, so make sure that they at least clean up such mess the next time they run. Test generic/247, xfs/020 (fsfile) and generic/074 (fstest.$$.n) are the worst offenders, so just target these to being with.
