NVMFS

This project stores file metadata in NVM-DB and stores filedata in DAOS.

This project include two FUSE-based filesystems：Metafs and Rocksfs. Metafs must work on NVM and Rocksfs needn't.

Source Code Structure

• MetaDB: A non-volatile memory-based high performance KV storage developed by my senior. I use it to store filesystem's metadata in metafs.

• metafs：A filesystem using MetaDB to store filesystem's metadata.

• rocksfs: A filesystem using RocksDB to store filesystem's metadata.

Use cmake and make to compile Metafs or Rocksfs.

Use test.sh in xxfs's folder to mount and use the filesystem.

Use filebench to test performance.
