Installation Instructions for Software RAID

It is possible install Ubuntu Server on Software RAID (RAID1) devices on ppc64el-based systems, with Ubuntu Server 14.04.4 LTS or later, and 16.04 LTS or later.

  • The requirement is that PReP partition(s) must be created directly on top of the component device(s) (not on top of the Software RAID device):

    • in only one of the component devices with Ubuntu Server 14.04.4 LTS or later

    • in one or more of the component devices with Ubuntu Server 16.04 LTS or later

  • Other partitions (for /, /boot, /home etc.) can be created on top of the Software RAID device.

The instructions for this process are described in this page.

Overview

  1. Select Manual partitioning
  2. Initialize the partition table of the component devices
  3. Create PReP partition(s) in component device(s)
  4. Configure the Software RAID device (RAID1)
  5. Partition the Software RAID device (with either Manual or Guided partitioning)
  6. Proceed with the normal installation process

Example

This example illustrates the installation process for Software RAID1 with 2 component devices and Guided partitioning with LVM.

The steps and installation dialogs are based on Ubuntu Server 14.04.4 LTS, and are closely similar on Ubuntu Server 16.04 LTS (different output).

All steps are performed in the Partition disks dialog.

Select Manual partitioning

Manual partitioning is required initially, in order to prepare the disks (e.g., initialize the partition table, and create PReP partition(s)) and configure Software RAID.

Afterward, it is possible to use Guided partitioning.

  • Select Manual:

  │ The installer can guide you through partitioning a disk (using          │
  │ different standard schemes) or, if you prefer, you can do it            │
  │ manually. With guided partitioning you will still have a chance later   │
  │ to review and customise the results.                                    │

Partition the Software RAID device (with either Manual or Guided partitioning)

Partition the device normally, either in Manual or Guided partitioning mode. This example uses Guided partitioning.

Warning /!\ Note: There's a bug (LP 1615650) with Guided Partitioning for Software RAID devices with NVMe component devices: the Software RAID device is not listed in the Select disk to partition prompt. (affects Ubuntu Server LTS 16.04 and 16.04.1; fixed for 16.04.2 and later, fixed on 16.04 ISO daily builds as of 14-Sep-2016)

There are 2 options:

  1. Use Manual partitioning.
  2. Use Guided partitioning with this workaround:

    1. In the Partition disks dialog, select Go Back until the main menu, then select Execute a Shell

    2. Run this command: 
        ~ # sed -i '243 i */nvme*) ;;' /lib/partman/lib/auto-shared.sh; exit

    3. Select Partition disks and continue the installation normally.

  • Select Guided partitioning:

Diagnosing Network Speed with Iperf

Updated by Nick Brewer

Contribute on GitHub

View Project | View File | Edit File

Linux systems administrators and network administrators often find diagnosing network speed degradation complicated, as there are very few tools available to diagnose these issues. Iperf is a command-line tool used in the diagnostics of network speed issues.

Diagnosing Network Speed with Iperf

Iperf measures the maximum network throughput a server can handle. It is particularly useful when experiencing network speed issues, as you can use Iperf to determine which server is unable to reach maximum throughput.

Installing Iperf

The installation section assumes that you are the root user. If you are not using the super user, you will need to use sudo before each command.

Debian and Ubuntu

You can use apt-get to install Iperf on Debian and Ubuntu:

1
 
apt-get install iperf

CentOS

CentOS repositories do not have Iperf by default. Use the EPEL repository, which is a repository used to install third-party software packages on RedHat systems such as RHEL and CentOS:

1
2
3
 
yum install epel-release
yum update
yum install iperf

Fedora

To install Iperf on your Fedora instance run:

1
2
 
yum update
yum install iperf

Arch Linux

To install Iperf on your Arch Linux instance run:

1
 
pacman -S iperf

Gentoo

Using Portage, install Iperf on your Gentoo instance:

1
 
emerge iperf

If you have not yet run emerge --sync you may need to do so before it will allow you to install the Iperf package. Additionally, by default you will need to substitute each iperf command with /usr/bin/iperf3. This path may differ dependent on your Iperf version.

Using Iperf

Iperf must be installed on both computers you are testing the connection between. If you are using a Unix or Linux-based operating system on your personal computer, you may be able to install Iperf on your local machine. If you are testing the throughput of your Linode, however, it’s better to use another server as the end point, as your local ISP may impose network restrictions that can affect the results of your test.

TCP Clients & Servers

Iperf requires two systems because one system must act as a server, while the other acts as a client. The client connects to the server you’re testing the speed of.

  1. On the Linode you wish to test, launch Iperf in server mode:

    1
    		 
    iperf -s

    You should see output similar to:

    1
2
3
4
    		 
     ------------------------------------------------------------
 Server listening on TCP port 5001
 TCP window size: 85.3 KByte (default)
 ------------------------------------------------------------

  2. On your second Linode, connect to the first. Replace 198.51.100.5 with the first Linode’s IP address.

    1
    		 
    iperf -c 198.51.100.5

    The output should be similar to:

    1
2
3
4
5
6
7
    		 
    ------------------------------------------------------------
Client connecting to 198.51.100.5, TCP port 5001
TCP window size: 45.0 KByte (default)
------------------------------------------------------------
[  3] local 198.51.100.6 port 50616 connected with 198.51.100.5 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.1 sec  1.27 GBytes  1.08 Gbits/sec

  3. You will also see the connection and results on your Iperf server. This will look similar to:

    1
2
3
4
5
6
7
    		 
    ------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[  4] local 198.51.100.5 port 5001 connected with 198.51.100.6 port 50616
[ ID] Interval       Transfer     Bandwidth
[  4]  0.0-10.1 sec  1.27 GBytes  1.08 Gbits/sec

  4. To stop the Iperf server process, press CTRL + c.

UDP Clients & Servers

Using Iperf, you can also test the maximum throughput achieved via UDP connections.

  1. Start a UDP Iperf server:

    1
    		 
    iperf -s -u

    The output will be similar to:

    1
2
3
4
5
    		 
    ------------------------------------------------------------
Server listening on UDP port 5001
Receiving 1470 byte datagrams
UDP buffer size:  208 KByte (default)
------------------------------------------------------------

  2. Connect your client to your Iperf UDP server. Replace 198.51.100.5 with your IP address:

    1
    		 
    iperf -c 198.51.100.5 -u

    The -u option we’ve passed tells Iperf that we are connecting via UDP. This is important, because we want to see the maximum throughput achieved via UDP. The output should be similar to:

    1
2
3
4
5
6
7
8
9
10
11
    		 
    ------------------------------------------------------------
Client connecting to 198.51.100.5, UDP port 5001
Sending 1470 byte datagrams
UDP buffer size:  208 KByte (default)
------------------------------------------------------------
[  3] local 198.51.100.6 port 58070 connected with 198.51.100.5 port 5001
[ ID] Interval       Transfer     Bandwidth
[  3]  0.0-10.0 sec  1.25 MBytes  1.05 Mbits/sec
[  3] Sent 893 datagrams
[  3] Server Report:
[  3]  0.0-10.0 sec  1.25 MBytes  1.05 Mbits/sec   0.084 ms    0/  893 (0%)

    Looking at the output we have received, 1.05 Mbits/sec is considerably less than what we received on the TCP tests. It is also considerably less than the maximum outbound bandwidth cap provided by the 1GB Linode. This is because Iperf limits the bandwidth for UDP clients to 1 Mbit per second by default.

  3. You can change this with the -b flag, replacing the number after with the maximum bandwidth rate you wish to test against. If you are testing for network speed, we recommend setting this number above the maximum bandwidth cap provided by Linode. For example, this test was run on a 1GB Linode:

    1
    		 
    iperf -c 198.51.100.5 -u -b 1000m

    This tells the client that we want to achieve a maximum of 1000 Mbits per second if possible. The -b flag only works when using UDP connections, since Iperf does not set a bandwidth limit on the TCP clients.

    The output should be similar to:

    1
2
3
4
5
6
7
8

    Now that is considerably better than the 1.05 Mbits/sec we were seeing earlier!

Bidirectional Tests

In some cases, you may want to test both servers for the maximum amount of throughput. This can easily be done using the built-in bidirectional testing feature Iperf offers.

Run the following command to test both connections:

1
 
iperf -c 198.51.100.5 -d

The result is that Iperf will start a server and a client connection on the original client server (198.51.100.6). Once this has been done, Iperf will connect the original Iperf server to the client connection, which is now acting as both a server connection and a client connection. This will look similar

[  5]  0.0-10.2 sec  1.28 GBytes  1.08 Gbits/sec

Options

Option Description
-f Change the format in which the tests are run. For example, you can use -f k to get results in Kbits per second instead of Mbits per second. Valid options include m (Mbits, default), k (Kbits), K (KBytes), and M (MBytes).
-V Forces Iperf to use IPv6 rather than IPv4.
-i Changes the interval between periodic bandwidth tests. For example, -i 60 will make a new bandwidth report every 60 seconds. The default is zero, which performs one bandwidth test.
-p Changes the port. When not specified, the default port is 5001. You must use this flag on both the client and server.
-B Binds Iperf to a specific interface or address. If passed through the server command, the incoming interface will be set. If passed through the client command, the outgoing interface will be set.
