As I pointed out in my previous thread [1], there are some testcases in fstests that are failing for FSB 16k, 32k and 64k due to the filesystem **size** under test. These are failures **upstream** and not due to the ongoing LBS work. fstests creates a lot of tiny filesystems to perform some tests. Even though the minimum fs size allowed to create XFS filesystem is 300 MB, we have special condition in mkfs to allow smaller filesystems for fstest[2] (This took some time to figure out as I was splitting my hair how fstest is able to create XFS on top of 25MB images). The problem comes when we have FSB 16k, 32k and 64k. As we will require more log space when we have this feature enabled, some test cases are failing with the following error message: max log size XXX smaller than min log size YYY, filesystem is too small Most test cases run without this error message with **rmapbt disabled** for 16k and 64k (see the test matrix below). What should be the approach to solve this issue? 2 options that I had in my mind: 1. Similar to [2], we could add a small hack in mkfs xfs to ignore the log space requirement while running fstests for these profiles. 2. Increase the size of filesystem under test to accommodate these profiles. It could even be a conditional increase in filesystem size if the FSB > 16k to reduce the impact on existing FS test time for 4k FSB. Let me know what would be the best way to move forward. Here are the results: Test environment: kernel Release: 6.8.0-rc1 xfsprogs: 6.5.0 Architecture: aarch64 Page size: 64k Test matrix: | Test | 32k rmapbt=0 | 32k rmapbt=1 | 64k rmapbt=0 | 64k rmapbt=1 | | -------- | --------- | --------- | --------- | --------- | | generic/042 | fail | fail | fail | fail | | generic/081 | fail | fail | pass | fail | | generic/108 | fail | fail | pass | fail | | generic/455 | fail | fail | pass | fail | | generic/457 | fail | fail | pass | fail | | generic/482 | fail | fail | pass | fail | | generic/704 | fail | fail | pass | fail | | generic/730 | fail | fail | pass | fail | | generic/731 | fail | fail | pass | fail | | shared/298 | pass | pass | pass | fail | 16k fails only on generic/042 for both rmapbt=0 and rmapbt=1 [1] https://lore.kernel.org/all/7964c404-bc9d-47ef-97f1-aaaba7d7aee9@xxxxxxxxxxx/ [2] xfsprogs commit: 6e0ed3d19c54603f0f7d628ea04b550151d8a262 -- Regards, Pankaj
