Build Status

node-zfs

node-zfs is a simple wrapper around the zfs and zpool commands. It enables ZFS management scripting using Node.js under SmartOS, Solaris, OpenIndiana and FreeBSD. Node-zfs is also tested successfully on Ubuntu.

Installation

Using npm:

$ npm install --save zfs

Usage

var zfs-filesystem = require('zfs');

##Now you can address the zfs library as follows:

To use the zfs command implementation:

zfs-filesystem.zfs.

###To use the zpool implementation:

zfs-filesystem.zpool.

Implemented commands for the ZFS tool

###ZFS list

The list command lists a specific zfs dataset or all datasets. All possible options can be found inside the lib/zfs.js file.

zfs-filesystem.zfs.list(function (err, list) {
    console.log(list)
});

###ZFS get

Get the parameters of a specific dataset or all datasets. All possible options can be found inside the lib/zfs.js file.

var opts = {
    name: 'my-dataset-name',
    property: 'quota'
};

zfs-filesystem.zfs.get(opts, function (err, options) {
    console.log(options);
});

###ZFS set

Set a specific option for a given dataset. All possible options can be found inside the lib/zfs.js file.

var opts = {
    name: 'my-dataset-name',
    property: 'quota',
    value: '1024G'
};

zfs-filesystem.zfs.set(opts, function (err, output) {
    console.log(output);
});

###ZFS Destroy

Remove a dataset from the ZFS filesystem

var opts = {
    name: 'my-dataset-name'
};

zfs-filesystem.zfs.destroy(opts, function (err, output) {
    console.log(output);
});

###ZFS Create

Create a new dataset inside the ZFS filesystem. All possible options can be found inside the lib/zfs.js file.

var opts = {
    name: 'my-new-dataset-name'
};

zfs-filesystem.zfs.create(opts, function (err, output) {
    console.log(output);
});

###ZFS Snapshot

Creates a snapshot with the given name. All possible options can be found inside the lib/zfs.js file.

var opts = {
    name: 'my-new-snapshot-name',
    dataset: 'my-dataset-name'
};

zfs-filesystem.zfs.snapshot(opts, function (err, output) {
    console.log(output);
});

###ZFS Clone

Creates a clone of the given snapshot. All possible options can be found inside the lib/zfs.js file.

var opts = {
    snapshot: 'my-snapshot-name',
    dataset: 'my-mountpoint-name'
};

zfs-filesystem.zfs.clone(opts, function (err, output) {
    console.log(output);
});

ZFS Mount

Mount the filesystem with the specified name or all filesystems. All possible options can be found inside the lib/zfs.js file.

var opts = {
    dataset: 'my-filesystem-name'
};

zfs-filesystem.zfs.mount(opts, function (err, output) {
    console.log(output);
});

ZFS Unmount

Unmount the filesystem or the mountpoint or all filesystems. All possible options can be found inside the lib/zfs.js file.

var opts = {
    name: 'my-filesystem-name',
    force: true
};

zfs-filesystem.zfs.unmount(opts, function (err, output) {
    console.log(output);
});

ZFS Send

Initiates a send of a given snapshot and returns a readable stream. All possible options can be found inside the lib/zfs.js file.

var opts = {
    snapshot : '/pool/dataset@snapshot',
    verbose : true
};

zfs-filesystem.zfs.send(opts, function (err, sendStream) {
    sendStream.on('error', function (err) {
        console.error(err);
    });

    sendStream.on('verbose', function (data) {
        console.log(data);
    });

    sendStream.pipe(process.stdout).on('end', function () {
        console.log('done');
    });
});

ZFS Receive

Initiates a receive and returns a writable stream to which a send stream may be written. All possible options can be found inside the lib/zfs.js file.

var opts = {
    dataset : '/pool2/dataset',
    verbose : true
};

zfs-filesystem.zfs.receive(opts, function (err, receiveStream) {
    receiveStream.on('error', function (err) {
        console.error(err);
    });

    receiveStream.on('verbose', function (data) {
        console.log(data);
    });

    process.stdin.pipe(receiveStream).on('end', function () {
        console.log('done');
    });
});

Implemented commands for the ZPool tool

###ZPool Create

Creates a new storage pool containing the virtual devices specified. All possible options can be found inside the lib/zpool.js file.

var opts = {
    name: 'my-datastore',
    devices: ['/dev/vdb', '/dev/vdc']
};

zfs-filesystem.zpool.create(opts, function (err, output) {
    console.log(output);
});

###ZPool Add

Adds the specified virtual devices to the given pool. All possible options can be found inside the lib/zpool.js file.

var opts = {
    name: 'my-datastore',
    devices: '/dev/vdd'
};

zfs-filesystem.zpool.add(opts, function (err, output) {
    console.log(output);
});

###ZPool Set

Sets the given property on the specified pool. See the zpool manpage for possible options and values.

var opts = {
    name: 'my-datastore',
    property: 'comment',
    value: 'Added some comment to a datastore'
};

zfs-filesystem.zpool.set(opts, function (err, output) {
    console.log(output);
});

###ZPool Destroy

Destroys the given pool, freeing up any devices for other use.

var opts = {
    name: 'my-datastore',
};

zfs-filesystem.zpool.destroy(opts, function (err, output) {
    console.log(output);
});

###ZPool List

Lists the given pools along with a health status and space usage. If no pools are specified, all pools in the system are listed.

zfs-filesystem.zpool.list(function (err, output) {
    console.log(output);
});

###ZPool Get

Retrieves the given list of properties. When no name and property specified, it shows all properties for all datastores. See the zpool manpage for possible options and values.

zfs-filesystem.zpool.get(function (err, output) {
