Rbfs

Rbfs combines hosts files with rsync to simplify keeping a consistent set of files on multiple servers.

Features

• Multithreaded sync
• Partial sync using a subpath
• Summary exit code indicating success of all nodes.
• Configurable timeout to avoid long delays on inaccessible nodes.

Options

Most options can be specified via command-line arguments or in the config file. Arguments specified on the command line supersede those specified in the config file.

Command line arguments

Usage: rbfs [options]
    -c, --config FILE                Configuration file
    -h, --hosts FILE                 Hosts file
    -r, --root ROOT                  Root path to sync
    -e, --remote-root ROOT           Remote root path to sync
    -s, --subpath PATH               Subpath of root to sync
    -v, --[no-]verbose               Print extra debugging info
    -d, --dry                        Test config settings
    -t, --[no-]threaded              Run all hosts concurrently
        --timeout TIMEOUT            Set I/O timeout

Config file settings

• hosts: Hosts file
• root: Root path to sync from
• remote_path: Remote root path to sync to (default: the value of root)
• subpath: Subpath of root to sync (default: /)
• verbose: Print extra debugging info (default: false)
• dry: Test config settings (default: false)
• threaded: Run all hosts concurrently (default: false)
• timeout: Set I/O timeout in seconds (default: 60)

Usage

Basic Sample

Given a sample hosts file (/etc/sync.hostlist):

1.1.1.1 server-a
2.2.2.2 server-b

It is possible to ensure that both server-a and server-b have an identical directory (/path/to/filestore) using rbfs:

rbfs --hosts /etc/sync.hostlist --root /path/to/filestore

The output of the command would be as follows:

Syncing /path/to/filestore...
server-a: Success
server-b: Success

Config File

It is also possible to create syncing profiles using Rbfs' config file format.

Creating a profile (/etc/rbfs/filestore.yml) for the Basic Sample would look this:

---
  hosts: /etc/sync.hostlist
  root: /path/to/filestore

To use this profile you would run Rbfs with the --config option:

rbfs --config /etc/rbfs/filestore.yml
