This patchset add new stress test cases for btrfs by running two different btrfs operations simultaneously under fsstress to ensure btrfs doesn't hang or oops in such situations. btrfs scrub and btrfs check will be run after each test. The test matrix is the combination of 6 btrfs operations: balance create/mount/umount/delete subvolume replace device scrub defrag remount with different compress algorithms Short descriptions: 059: balance-subvolume 060: balance-scrub 061: balance-defrag 062: balance-remount 063: balance-replace 064: subvolume-replace 065: subvolume-scrub 066: subvolume-defrag 067: subvolume-remount 068: replace-scrub 069: replace-defrag 070: replace-remount 071: scrub-defrag 072: scrub-remount 073: defrag-remount Some issues I've seen: 1. subvolume cannot be mounted with selinux context, so you may see such logs in dmesg SELinux: mount invalid. Same superblock, different security settings for (dev dm-8, type btrfs) I've reported the bug to btrfs list, see [BUG] cannot mount subvolume with selinux context http://www.spinics.net/lists/linux-btrfs/msg36779.html 2. btrfs replace operation always returns ENOENT if balance is running So in 063.full you'll see ERROR: ioctl(DEV_REPLACE_START) failed on "/mnt/testarea/scratch": No such file or directory, no error Not sure if it's btrfs bug, at least I think the error code is misleading 3. replace operation hangs the kernel(3.16-rc4+ and 3.17-rc2+) with fsstress running So case 064/068/069/070 will hang Changes since v2: - mount subvolume at $TEST_DIR/$seq.mnt not $tmp.mnt - don't rm -rf $tmp.* which is dangerous - remove unnecessary btrfs filesystem sync operation - update _scratch_pool_mkfs to deal with dup profile - add more comments for each stress operation - rename _btrfs_stress_remount to _btrfs_stress_remount_compress (hope it's better...) - add _btrfs_get_profile_configs to remove duplicated test case array in each case - use _require_scratch_nocheck and _check_scratch_fs after each loop Changes since v1: - put common operations in common/rc as functions and share them across these tests - append mkfs options to _scratch_mkfs and _scratch_pool_mkfs instead of updating $MKFS_OPTIONS - rebase on top of master and re-number starting from btrfs/059 Thanks, Eryu Guan Eryu Guan (15): btrfs: new test to run btrfs balance and subvolume test simultaneously btrfs: new test to run btrfs balance and scrub simultaneously btrfs: new test to run btrfs balance and defrag operations simultaneously btrfs: new case to run btrfs balance and remount with different compress algorithms btrfs: new case to run btrfs balance and device replace operations simultaneously btrfs: new case to run btrfs subvolume create/delete operations and device replace simultaneously btrfs: new case to run btrfs subvolume create/delete operations and scrub simultaneously btrfs: new case to run btrfs subvolume create/delete and defrag operations simultaneously btrfs: new case to run subvolume create/delete and remount with defferent compress algorithms btrfs: new case to run device replace and scrub operations simultaneously btrfs: new case to run device replace and defrag operations simultaneously btrfs: new case to run device replace and remount with different compress algorithms simultaneously btrfs: new case to run btrfs scrub and defrag operations simultaneously btrfs: new case to run btrfs scrub and remount with different compress algorithms simultaneously btrfs: new case to run defrag and remount with different compress algorithms simultaneously common/rc | 225 +++++++++++++++++++++++++++++++++++++++++++++++++++- tests/btrfs/059 | 115 +++++++++++++++++++++++++++ tests/btrfs/059.out | 2 + tests/btrfs/060 | 114 ++++++++++++++++++++++++++ tests/btrfs/060.out | 2 + tests/btrfs/061 | 116 +++++++++++++++++++++++++++ tests/btrfs/061.out | 2 + tests/btrfs/062 | 114 ++++++++++++++++++++++++++ tests/btrfs/062.out | 2 + tests/btrfs/063 | 122 ++++++++++++++++++++++++++++ tests/btrfs/063.out | 2 + tests/btrfs/064 | 123 ++++++++++++++++++++++++++++ tests/btrfs/064.out | 2 + tests/btrfs/065 | 115 +++++++++++++++++++++++++++ tests/btrfs/065.out | 2 + tests/btrfs/066 | 117 +++++++++++++++++++++++++++ tests/btrfs/066.out | 2 + tests/btrfs/067 | 116 +++++++++++++++++++++++++++ tests/btrfs/067.out | 2 + tests/btrfs/068 | 123 ++++++++++++++++++++++++++++ tests/btrfs/068.out | 2 + tests/btrfs/069 | 125 +++++++++++++++++++++++++++++ tests/btrfs/069.out | 2 + tests/btrfs/070 | 123 ++++++++++++++++++++++++++++ tests/btrfs/070.out | 2 + tests/btrfs/071 | 116 +++++++++++++++++++++++++++ tests/btrfs/071.out | 2 + tests/btrfs/072 | 114 ++++++++++++++++++++++++++ tests/btrfs/072.out | 2 + tests/btrfs/073 | 116 +++++++++++++++++++++++++++ tests/btrfs/073.out | 2 + tests/btrfs/group | 15 ++++ 32 files changed, 2035 insertions(+), 4 deletions(-) create mode 100755 tests/btrfs/059 create mode 100644 tests/btrfs/059.out create mode 100755 tests/btrfs/060 create mode 100644 tests/btrfs/060.out create mode 100755 tests/btrfs/061 create mode 100644 tests/btrfs/061.out create mode 100755 tests/btrfs/062 create mode 100644 tests/btrfs/062.out create mode 100755 tests/btrfs/063 create mode 100644 tests/btrfs/063.out create mode 100755 tests/btrfs/064 create mode 100644 tests/btrfs/064.out create mode 100755 tests/btrfs/065 create mode 100644 tests/btrfs/065.out create mode 100755 tests/btrfs/066 create mode 100644 tests/btrfs/066.out create mode 100755 tests/btrfs/067 create mode 100644 tests/btrfs/067.out create mode 100755 tests/btrfs/068 create mode 100644 tests/btrfs/068.out create mode 100755 tests/btrfs/069 create mode 100644 tests/btrfs/069.out create mode 100755 tests/btrfs/070 create mode 100644 tests/btrfs/070.out create mode 100755 tests/btrfs/071 create mode 100644 tests/btrfs/071.out create mode 100755 tests/btrfs/072 create mode 100644 tests/btrfs/072.out create mode 100755 tests/btrfs/073 create mode 100644 tests/btrfs/073.out -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
