If cases won't fail when > reflink disabled, I'll focusing on solving the warning when reflink enabled. My first run on 6.1-rc3 with reflink disabled was clean. Then I ran a few tests with reflink enabled, and they all failed as expected. Then I ran the no-reflink tests again, and then they all failed, too. Nothing changed between test configs, I didn't even reboot the test machine: $ history |tail -5 500 sudo ./run_check.sh --mkfs-opts "-m rmapbt=1,reflink=0" --run-opts "-s xfs_dax xfs/55[12]" 501 sudo ./run_check.sh --mkfs-opts "-m rmapbt=1,reflink=0" --run-opts "-s xfs_dax_noreflink generic/051 generic/068 generic/074 generic/075 generic/083 generic/112 generic/231 generic/232 generic/269 generic/270 generic/340 generic/388 generic/461 generic/471 generic/476 generic/519 generic/560 generic/561 generic/617 generic/650 generic/656 xfs/011 xfs/013 xfs/017 xfs/073 xfs/297 xfs/305 xfs/517 xfs/538" 502 sudo ./run_check.sh --mkfs-opts "-m rmapbt=1" --run-opts "-s xfs_dax generic/051 generic/068 generic/074 generic/075 generic/083 generic/112 generic/231 generic/232 generic/269 generic/270 generic/340 generic/388 generic/461 generic/471 generic/476 generic/519 generic/560 generic/561 generic/617 generic/650 generic/656 xfs/011 xfs/013 xfs/017 xfs/073 xfs/297 xfs/305 xfs/517 xfs/538" 503 sudo ./run_check.sh --mkfs-opts "-m rmapbt=1,reflink=0" --run-opts "-s xfs_dax_noreflink generic/051 generic/068 generic/074 generic/075 generic/083 generic/112 generic/231 generic/232 generic/269 generic/270 generic/340 generic/388 generic/461 generic/471 generic/476 generic/519 generic/560 generic/561 generic/617 generic/650 generic/656 xfs/011 xfs/013 xfs/017 xfs/073 xfs/297 xfs/305 xfs/517 xfs/538" 504 history |tail -5 $ The first noreflink run: SECTION -- xfs_dax_noreflink ========================= Failures: generic/471 generic/519 xfs/073 Failed 3 of 29 tests Which are typical failures for this config.
