Sure :) I've added btrfs regression test to my regular test list recently. For now, only default btrfs is tested by xfstests "auto" group. Sorry I'm not familar with btrfs test currently, I hit several test failures, need time to figure out which is test issue, which is progs' issue, which is kernel issue and which is known and unknown issue and so on. For example: btrfs/007 fails as: QA output created by 007 *** test send / receive -*** done +failed: '2097152000 200' +(see /var/lib/xfstests/results//btrfs/007.full for details) btrfs/060 blocks the whole test. Then btrfs/066 hang there after I skip btrfs/060. generic/363 fails as: QA output created by 363 fsx -q -S 0 -e 1 -N 100000 +READ BAD DATA: offset = 0x1fb5d, size = 0xc502, fname = /mnt/test/junk +OFFSET GOOD BAD RANGE +0x2716c 0x0000 0x7f91 0x0 +operation# (mod 256) for the bad data may be 127 +0x2716d 0x0000 0x917f 0x1 ... (Run 'diff -u /root/git/xfstests/tests/generic/363.out /root/git/xfstests/results//default/generic/363.out.bad' to see the entire diff) generic/427 fails as: QA output created by 427 -Success, all done. +pwrite: No space left on device ... (Run 'diff -u /root/git/xfstests/tests/generic/427.out /root/git/xfstests/results//default/generic/427.out.bad' to see the entire diff) generic/730 fails as: QA output created by 730 -cat: -: Input/output error ... (Run 'diff -u /root/git/xfstests/tests/generic/730.out /root/git/xfstests/results//default/generic/730.out.bad' to see the entire diff) and some random failures on different test env. and so on ... After I'm familar with known failures, I think things will get better. Please feel free to share known issues (that you know) to me. Besides btrfs, there're lots of filesystems, they all have different known/unknown failures. It's not easy for someone to check most of filesystems' test failures before release. I'll try to avoid critical issue, likes can't be built or installed, whole or most of tests broken, system destroy, and so on. But for some test failures, I might notice and remind in ANNOUNCE email, might not. Each release might have bugs, likes RHEL, likes SUSE, Debian ... *each release might have bugs, but we have to release, have to move on if there's not critical blocker bugs.* I'm sorry for the recent mess. I'll try my best to get xfstests back to track. I think things is getting better, last release is the first fix release for that. We'll have next fix release. Please be patient, if things is out of control, I'll think about reverting the whole feature.
