This series fixes few issues with verify, and introduces a new test suite. Inital few patches add the missing client/server support for verify_write_sequence. This also changes its behavior such that if verify_write_sequence is explicitly enabled fio will not disable it under any circumstance. Numerous header seed mismatch issues have been reported. This series introduces a new option verify_header_seed which is similar to verify_write_sequence, which allow users to disable any header seed verification. For certain workloads which used to overwrite header seed before verification, we simply disable the header seed checks now. This now includes a few more scenarios such as verify_only mode, read only workloads and workloads with norandommap, where the header seed match is not guaranteed. Few more fixes related to verify_offset, workloads that have offset modifiers, verification issue when multiple files are specified, are part of this series. Lastly this includes robust test suite for verify. CI run result: https://github.com/vincentkfu/fio/actions/runs/13552248490 Note: The fixes in this series doesn't cover experimental_verify and any workload with variable block sizes.
I have worked closely with Ankit on these patches and hope others can take a look to point out anything we may have missed.
