Summary: DB Stress to add --open_metadata_write_fault_one_in which would randomly fail in some file metadata modification operations during DB Open, including file creation, close, renaming and directory sync. Some operations can fail before and after the operations take place. If DB open fails, db_stress would retry without the failure ingestion, and DB is expected to open successfully. This option is enabled in crash test in half of the time. Some follow up changes would allow write failures in open time, and ingesting those failures in non-DB open cases. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8235 Test Plan: Run stress tests for a while and see failures got triggered. This can reproduce the bug fixed by https://github.com/facebook/rocksdb/pull/8192 and a similar one that fails when fsyncing parent directory.
