Requirements
- redundant storage for all my music
- fast network connection
- low power consumption
Solution
- 2 * Olimex Lime2 SBCs (read why here)
- 2 * 2.5" 1Tb HDDs
- Debian OS
- LizardFS
- OpenMediaVault
- SqueezeServer (my music player is an old Squeezebox - have thought about updating this to a SBC with Volumio - that's another project).
So, let's do this!
- Get the Lime2, install Debian on SD Card, connect to ethernet (I'm using Ethernet over power line)
- Connect via ssh with uname root, password olimex
- Hey - there it is! Let's apt-get update and upgrade.
- So I'll switch it off, and connect the HDD using SATA cable. The power for the SATA is next to the SATA connector on the Lime2.
- Now we need to format it.

We need to format the disk and create a file system, let's go for ext4
