![]() ![]() Remember to change sda1 and sdb1 to suit your configuration: Now it’s time to create our RAID-1 volume. The installation should finish after this. You should now see the package configuration interface:Ĭhoose OK and then go with the default value of ‘all’. Next we’re going to install the software RAID controller called mdadm: This will install any updates to installed software on our Raspberry Pi. Step 2 – Install the software RAID controller Repeat the above for all the devices in your RAID array. Now type ‘ w‘ to write the changes to the device. For each of the options, we’re going with the default values to hit enter for each until the interactive prompt reads ‘Command (m for help):’ again. This will create an empty DOS partition table.Īfter this type ‘ n‘ to create a new partition. When asked for a command to run, type ‘ o‘. Repeat the following for each device in your RAID array, switching ‘sda’ for the device being configured: Remember, in my example, sda and sdb are the flash devices, this may differ to yours. We’re going to use fdisk to configure our devices. Yours may differ so make a note of which devices are your flash storage which you intend to put into your RAID array. In my example, sda and sdb are the two 16GB Toshiba flash drives, with sdc being the 8GB boot flash drive. To begin, we need to list the block devices using the following command: Step 1 – Configure storage ready for the RAID array ![]() I find that the Corsair Voyager and Toshiba Flash drives tend to be quick and reliable. 1 x Raspberry Pi 3 – I’m not sure if this tutorial will work on a RPi Zero or Rpi 1 or 2.2 x Toshiba 16GB Flash storage – Used for our RAID-1 volume.See this tutorial for booting from a USB Flash Drive 1 x Toshiba 8GB Flash storage – Used for the OS.The setup I’ll be configuring is the following: The trade-off comes if you have multiple disk failures. RAID-5 offers both performance and good redundancy. RAID-5 stripes blocks of data across a minimum of three storage devices. There is a slight performance trade-off, but nothing noticeable under ordinary circumstances. If one disk fails, it can be replaced without any loss of data. RAID-1 mirrors the blocks of data across the storage devices in the array. RAID-1 is the level of RAID which this tutorial will work towards. If one of the disks fails, the data is lost or damaged for good across all the devices. The benefits are read and writes are very quick. RAID 0 sees blocks of data spread across two or more physical storage devices in the array. RAID allows us to use several hard drives or USB flash drives in clever ways to add speed, redundancy or larger combined volumes. There are various RAID levels, the most common are RAID-0, RAID-1 and RAID-5. RAID stands for Redundant Array of Independent Disks. View the Installing OwnCloud on Raspberry Pi tutorial. This tutorial is part one of two where we will use our RAID volume for creating our own cloud storage platform using OwnCloud. I’m going to assume that you’ve followed my previous tutorial on how to install and run Raspbian OS from a USB Flash Drive, although this isn’t necessary.Īs we’re using a software RAID controller, we can’t run the OS from our RAID volume, but we can use to for storage. RAID allows redundant, quick or extended storage depending on which RAID level you go with. With minimal soldering, he converted the Zero’s onboard female USB jacks into a male USB plug.In this tutorial, I will go through the steps necessary to create a RAID volume in Raspbian OS on your Raspberry Pi. His hack turned the Zero Pi into a USB dongle with shared internet, and he could install services like webmin, owncloud, and vnc making it a great all-in-one device! He aims to get the maximum benefit out of a Pi Zero without having to lug around any cables: “Just plug it in and you’re networked” Novaspirit has turned his Raspberry Pi Zero into a USB gadget, just like a RNDIS modem, with some easy steps. Thus, it can become a serial device with just a USB cable, an Ethernet device, MIDI device, camera, or just about anything else you can plug into a USB port. It comes with a USB OTG port, meaning it can function as a USB device rather than a USB host. The $5 Raspberry Pi Zero is a standalone computer that can be embedded in various applications, but maybe now it is time to add some extra features. ![]()
