Introduction

The storage driver implementation may be used to perform file non-blocking I/O. Typically used totest CIFS/HDFS/NFS shares mounted locally. However, testing distributed filesystems via the mounted shares may be not accurate due to additional VFS layer. The measured rates may be:

• Inadequately low due to frequent system calls
• Higher than network bandwidth due to local caching by VFS

Features

• Authentification: N/A
• Item types: data only (--> "file")
• Path listing input
• Automatic destination path creation on demand
• Data item operation types:
  • create, additional modes:
    • copy
  • read
    • full
    • random byte ranges
    • fixed byte ranges
    • content verification
  • update
    • full (overwrite)
    • random byte ranges
    • fixed byte ranges (with append mode)
  • delete
  • noop

Usage

Get the latest pre-built jar file which is available at: http://repo.maven.apache.org/maven2/com/github/emc-mongoose/mongoose-storage-driver-fs/ The jar file may be downloaded manually and placed into the <USER_HOME_DIR>/.mongoose/<VERSION>/ext directory of Mongoose to be automatically loaded into the runtime.

java -jar mongoose-<VERSION>.jar \
    --storage-driver-type=fs \
    --storage-net-node-addrs=<NODE_IP_ADDRS> \
    --storage-net-node-port=<NODE_PORT> \
    ...

Standalone

java -jar mongoose-<VERSION>.jar \
    --storage-driver-type=fs \
    ...
