How to setup a RAID system using USB sticks as storage media

I want to create an inexpensive self-hosted private git server with redundant storage. To that end I have bought a Raspberry Pi and configured both git
and ssh
on the Pi. I can access the Pi both from a LAN and remotely (by forwarding a port on my router to the Pi).
So the git server is already up and running. The last thing to do is redundant storage. Because I have a 7-port USB hub attached to my Pi, I would like to set up a RAID system using multiple identical USB sticks.
I have only conceptual knowledge of RAID. Therefore I do not know how to set it up and more importantly, whether it is possible with USB sticks connected to a hub.
So these are basically my questions
- Can you set up a RAID system using USB sticks as the storage media
- What software should I use
- Where can I find good tutorials / manuals for RAID systems
- In case RAID is impossible, how can I synchronize data across multiple USB sticks

Q#1: Can you set up a RAID system using USB sticks as the storage media
You should be able to use any block storage devices in a RAID. Any standard directions for setting up a RAID using SATA HDD's should be applicable when using USB storage as well. You'll have to set it up so that the USB devices are assembled as members of the RAID array.
Q#2: What software should I use
I would use the mdadm
software which is typically included with most Linux distros.
Example
$ sudo mdadm --create --verbose /dev/md0 --level=1 /dev/sda1 /dev/sdb1
mdadm: Note: this array has metadata at the start and
may not be suitable as a boot device. If you plan to
store '/boot' on this device please ensure that
your boot-loader understands md/v1.x metadata, or use
--metadata=0.90
mdadm: size set to 976629568K
Continue creating array? y
mdadm: Defaulting to version 1.2 metadata
mdadm: array /dev/md0 started.
Change the devices to the ones used by the USB storage devices. Then assemble the array:
$ sudo mdadm --assemble --scan
$ sudo mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1
Once assembled:
$ sudo mdadm --detail /dev/md0
/dev/md0:

Q#3: Where can I find good tutorials / manuals for RAID systems
A simple search on Google will turn up many options. For example this one: Tutorial: mdadm Software RAID on Ubuntu / Debian Systems.
This is good. Im curious about detaching devices, considering the subject is removable media. Is it easily handled?

One concern (nearly) unique to the Pi is the loss of all RAID drives at once when the USB system crashes. This is similar to having a RAID controller card fail, but is far more common.

Thank you very much. This helped me a lot. I ordered 4 identical 32 GB USB sticks. I intend to set up a RAID level 10 system (two RAID 1 sets combined into a larger RAID 0 unit). How do I go about rebooting? Is everything lost when I reboot the Pi? Is the RAID level 10 system available after reboot?
– Aeronaelius
Mar 23 '14 at 17:20
@cfbaptista - the RAID should persist b/w reboots, it will need to be started up as part of the Pi's booting process using mdadm.

One concern (nearly) unique to the Pi is the loss of all RAID drives at once when the USB system crashes. This is similar to having a RAID controller card fail, but is far more common.

Thank you very much. This helped me a lot. I ordered 4 identical 32 GB USB sticks. I intend to set up a RAID level 10 system (two RAID 1 sets combined into a larger RAID 0 unit). How do I go about rebooting? Is everything lost when I reboot the Pi? Is the RAID level 10 system available after reboot?

@cfbaptista - the RAID should persist b/w reboots, it will need to be started up as part of the Pi's booting process using mdadm.

This is good. Im curious about detaching devices, considering the subject is removable media. Is it easily handled?
