Summary: Write and metadata error injection during DB open was enabled in https://github.com/facebook/rocksdb/issues/8474. This causes crash tests to fail very frequently due to another fault injection feature that deletes files created after the last dir sync during DB open. In real life, a similar failure would happen if the FS returns error on the CURRENT file rename, but the rename actually succeeded and got partially persisted (dir entry for the old CURRENT file got removed, but the entry for the new one is not persisted). Temporarily disable the fault injection feature until we figure out the likelihood of this bug happening and the proper way to fix it.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
