Hi Andrey, This is a good start, but I think it can be improved further.

There are a few repeating > steps. The indent of avaliable environment variables is not clear. A couple of housekeeping notes first. Commit messages should be line wrapped at 68-72 columns so that they can easily be cut/paste/quoted into email which typically wraps at 68-72 columns. If you use vim, you can set up a column marker and text wrapping to do this automatically with .vimrc rules like this: " default text width is 80 columns set textwidth=80 " set the textwidth to 68 characters for guilt commit messages au BufNewFile,BufRead guilt.msg.*,.gitsendemail.*,git.*,*/.git/* set tw=68 And you set the textwidth highlight with: " highlight textwidth set cc=+1 You'll want to highlight whitespace damage, too. " highlight whitespace damage highlight RedundantSpaces ctermbg=red guibg=red match RedundantSpaces /\s\+$\| \+\ze\t/ Also, if you use mutt for email, then add this to your .muttrc: set editor="vim -c 'set ft=mail tw=68'" And all it will set up the defaults for 68 column mail editting by default. IOWs, the textwidth the editor defaults to will now change automatically depending on whether you are writing email, editting code or git commit messages... > This patch: > - Update package dependencies for Ubuntu/Debian/RHEL/CentOS/Fedora > - Unify list of packages between Ubuntu/Debian and RHEL/CentOS/Fedora > - Add list of tool packages for other FS > - Add links to tools not in the standard repository for RHEL/CentOS > - Drop xfsprogs-qa-devel reference for old systems > - Replace note about EPEL with installation step with link to Fedora > manual > - Add configuration examples in 'Setup Environment' > - Small clarification details, such as size of the partition and > KCONFIG_PATH description > - Removal of repeating steps (install administrative tools, partitions > content) > - Restructuring and formatting of "BUILDING THE FSQA SUITE" section > - Drop IRIXDEV references in variable set up Normally we ask for one change per patch so that we can see the individual changes in isolation.

Also, rather than include a couple of filesystem specific packages here, I'd list all the packages that are needed regardless of the fs being tested. This would mean e2fsprogs and xfsprogs will be in the above list, but xfsdump and xfslibs-dev shouldn't be. They would get listed in #2: > +2. (Optional) For udf, exfat, f2fs, ocfs2 install: "2.

The config is used by tests to check if kernel feature is enabled. I find this harder to read that the previous list - it much denser text with less whitespace, so individual rules/notes are harder to separate. I would separate this out into multiple groups that are blank line separated. e.g: - Extra TEST device specifications: - Set TEST_LOGDEV to "device for test-fs external log" - Set TEST_RTDEV to "device for test-fs realtime data" - If TEST_LOGDEV and/or TEST_RTDEV, these will always be used. - Extra SCRATCH device specifications - Set SCRATCH_LOGDEV to "device for scratch-fs external log" - Set SCRATCH_RTDEV to "device for scratch-fs realtime data" - If SCRATCH_LOGDEV and/or SCRATCH_RTDEV, the USE_EXTERNAL environment variable set to "yes" will enable their use. - Tape device specification for xfsdump testing: - Set TAPE_DEV to "tape device for testing xfsdump". Note that if testing xfsdump, make sure the tape devices have a tape which can be overwritten. - Set RMT_TAPE_DEV to "remote tape device for testing xfsdump" (group xfs repair/check configs together) (group dump configs together) (etc) This makes it easier to read and to find different options that someone might want to use. Cheers, Dave.

If this is not provided, many tests will - not be run. - (SCRATCH and TEST must be two DIFFERENT partitions) - OR - - for btrfs only: some btrfs test cases will need 3 or more independent - SCRATCH disks which should be set using SCRATCH_DEV_POOL (for eg: - SCRATCH_DEV_POOL="/dev/sda /dev/sdb /dev/sdc") with which - SCRATCH_DEV should be unused by the tester, and for the legacy - support SCRATCH_DEV will be set to the first disk of the - SCRATCH_DEV_POOL by xfstests script. - - - setup your environment - Quick start: - - copy local.config.example to local.config and edit as needed - Or: - - setenv TEST_DEV "device containing TEST PARTITION" - - setenv TEST_DIR "mount point of TEST PARTITION" - - optionally: - - setenv SCRATCH_DEV "device containing SCRATCH PARTITION" OR - (btrfs only) setenv SCRATCH_DEV_POOL "to 3 or more SCRATCH disks for - testing btrfs raid concepts" - - setenv SCRATCH_MNT "mount point for SCRATCH PARTITION" - - setenv TAPE_DEV "tape device for testing xfsdump" - - setenv RMT_TAPE_DEV "remote tape device for testing xfsdump" - - setenv RMT_IRIXTAPE_DEV "remote IRIX tape device for testing xfsdump" - - setenv SCRATCH_LOGDEV "device for scratch-fs external log" - - setenv SCRATCH_RTDEV "device for scratch-fs realtime data" - - setenv TEST_LOGDEV "device for test-fs external log" - - setenv TEST_RTDEV "device for test-fs realtime data" - - if TEST_LOGDEV and/or TEST_RTDEV, these will always be used. - - if SCRATCH_LOGDEV and/or SCRATCH_RTDEV, the USE_EXTERNAL - environment variable set to "yes" will enable their use. - - setenv DIFF_LENGTH "number of diff lines to print from a failed test", - by default 10, set to 0 to print the full diff - - setenv FSTYP "the filesystem you want to test", the filesystem - type is devised from the TEST_DEV device, but you may want to - override it; if unset, the default is 'xfs' - - setenv FSSTRESS_AVOID and/or FSX_AVOID, which contain options - added to the end of fsstresss and fsx invocations, respectively, - in case you wish to exclude certain operational modes from these - tests. - - set TEST_XFS_REPAIR_REBUILD=1 to have _check_xfs_filesystem - run xfs_repair -n to check the filesystem; xfs_repair to rebuild - metadata indexes; and xfs_repair -n (a third time) to check the - results of the rebuilding. - - xfs_scrub, if present, will always check the test and scratch - filesystems if they are still online at the end of the test. - It is no longer necessary to set TEST_XFS_SCRUB. - - setenv LOGWRITES_DEV to a block device to use for power fail - testing. - - setenv PERF_CONFIGNAME to a arbitrary string to be used for - identifying the test setup for running perf tests. This should - be different for each type of performance test you wish to run so - that relevant results are compared. For example 'spinningrust' - for configurations that use spinning disks and 'nvme' for tests - using nvme drives. - - set USE_KMEMLEAK=yes to scan for memory leaks in the kernel - after every test, if the kernel supports kmemleak. - - set KEEP_DMESG=yes to keep dmesg log after test - - Set TEST_FS_MODULE_RELOAD=1 to unload the module and reload - it between test invocations. This assumes that the name of - the module is the same as FSTYP. - - Set DUMP_CORRUPT_FS=1 to record metadata dumps of XFS or ext* - filesystems if a filesystem check fails. - - Set DUMP_COMPRESSOR to a compression program to compress - metadumps of filesystems. This program must accept '-f' and the - name of a file to compress; and it must accept '-d -f -k' and - the name of a file to decompress. In other words, it must - emulate gzip. - - Set MIN_FSSIZE to specify the minimal size (bytes) of a - filesystem we can create. Setting this parameter will - skip the tests creating a filesystem less than - MIN_FSSIZE. - - Set MODPROBE_PATIENT_RM_TIMEOUT_SECONDS to specify the amount of - time we should try a patient module remove. The default is 50 - seconds. Set this to "forever" and we'll wait forever until the - module is gone. - - Set FORCE_XFS_CHECK_PROG=yes to have _check_xfs_filesystem run - xfs_check to check the filesystem. As of August 2021, - xfs_repair finds all filesystem corruptions found by xfs_check, - and more, which means that xfs_check is no longer run by default. - - Set KCONFIG_PATH to specify your preferred location of kernel - config file. - - - or add a case to the switch in common/config assigning - these variables based on the hostname of your test - machine - - or add these variables to a file called local.config and keep that - file in your workarea. - - - if testing xfsdump, make sure the tape devices have a - tape which can be overwritten. - - - make sure $TEST_DEV is a mounted XFS partition - - make sure that $SCRATCH_DEV or $SCRATCH_DEV_POOL contains nothing useful - Running tests: - cd xfstests
The commands for package managers for both Ubuntu and RHEL weren't up-to-date. A few packages doesn't exist anymore or missing from the latest repositories (e.g. liburing-devel, btrfs-progs-devel). Ubuntu's list missed a few packages listed in RHEL's list. There are a few repeating steps. The indent of avaliable environment variables is not clear. This patch: - Update package dependencies for Ubuntu/Debian/RHEL/CentOS/Fedora - Unify list of packages between Ubuntu/Debian and RHEL/CentOS/Fedora - Add list of tool packages for other FS - Add links to tools not in the standard repository for RHEL/CentOS - Drop xfsprogs-qa-devel reference for old systems - Replace note about EPEL with installation step with link to Fedora manual - Add configuration examples in 'Setup Environment' - Small clarification details, such as size of the partition and KCONFIG_PATH description - Removal of repeating steps (install administrative tools, partitions content) - Restructuring and formatting of "BUILDING THE FSQA SUITE" section - Drop IRIXDEV references in variable set up Signed-off-by: Andrey Albershteyn <aalbersh@redhat.com> --- README | 342 ++++++++++++++++++++++++++++++++++----------------------- 1 file changed, 205 insertions(+), 137 deletions(-)
