Connecting Clients to your LizardFS installation

The most exciting part of this tutorial - you will finally be able to store files on your installation!

Linux / *NIX / *BSD / MacOS/X client

Install the client package

Check Getting and installing LizardFS for instructions how to install package

Example for Debian/Ubuntu:

$ apt-get install lizardfs-client

Make sure that the mfsmaster host is set in your /etc/hosts file. For our example configuration it would be:

192.168.16.100 mfsmaster

Create a mountpoint:

$ mkdir /mnt/lizardfs

Mount the filesystem to the mountpoint with just the default options from mfsmount.cfg if any:

$ mfsmount /mnt/lizardfs

That’s it.

On most systems adding big_writes to the options will significantly increase your throughput since it will force the fuse libraray to use writes > 4k. Example:

$ mfsmount -o big_writes,nosuid,nodev,noatime /mnt/lizardfs

will mount with fuse option: big_writes and default system mount options: nosuid, nodev and noatime.

You can now store your files on your brand new installation.

See the mfsmount(1) and mfsmount.cfg(5) manpage for more options

See FUSE to find out more about the fuse library.

Windows™ System Settings for LizardFS clients

Recommended tuning for Windows™ Clients:

  • Make sure your Power Options are set to “High Performance”.
  • Increase the number of Transfer and Receive Buffers in the configuration of your network interface
  • Increase the number of Queues available in your network interface setting
  • If at all possible set all network devices in your network to use Jumbo Frames.

The precise number for your respective host / NIC will be different in every setup, but they for sure will be far higher than the default settings.

Windows™ client

Install our client from exe package provided

Add your credentials and the address and port of the master server.

Select the drive you want your lizardFS filesystem to appear as in your windows session.

It should look like in the following image:

Windows™ CLI Client

Together with the GUI client the installation package adds a CLI client to your Windows™ system. It is located in:

C:\Program Files\LizardFS\lizardfscli.exe

Options are:

-H The address of the Master
-P The port to use at the Master
-D The drive letter to use for the mounted FS

Windows™ service

The Windows™ Client can also be run as a Windows™ Service. This is provided by the LizardSControler command.

Basic configuration

Minimal configuration:

LizardSControler -p -lic-file <LICENSE_FILE> -H <ADDRESS_OF_MASTER>

where LICENSE_FILE should be the name of the file containing a valid License and ADDRESS_OF_MASTER should be the hostname or IP address of the LizardFS master server.

Further configuration options

(Must follow the -p command)

Command Description
-H HOST set master server host address.
-P PORT set master server port. Default 9421.
-D DRIVE set <DRIVE> as a mount point i.e. D:. Default L:
-f SUBFOLDER mount only given LizardFS subfolder
-uid UID set new UID. Default is 1000.
-gid GID set new GID. Default is 1000.
-umask UMASK set new UMASK. Default is 000.
-pass PASS authenticate to LizardFS master using MD5 password.
-lic LICENSE set new LICENSE.
-lic-file LICENSE_FILE load new LICENSE from LICENSE_FILE.

Installation and runtime

After you have done the configration, you can add the service to your Windows system by running:

LizardSControler -i

and start it by running:

LizardSControler -s

If you would like to uninstall the service again, just run:

LizardSControler -u

To terminate the service, run:

LizardSControler -t
