| - | ===== Storage Setup ===== | ||
| - | |||
| - | The idea is to store your entire media collection on a redundant software RAID-1 array located on a different drive from the one where the Operating System is installed. In this way it will be easier to migrate to a new server in the future and your data will be safe from a disk failure. Now, there are different solutions you can choose from. You could go RAID-5, RAID-0+1, and many more combinations. RAID-1 has a few advantages for me which are: | ||
| - | * Good balance with wasted disk space (50% usage) | ||
| - | * Fast enough on read (reads will be balanced on both disks) | ||
| - | * Solid enough to survive one disk fail (provided you monitor the RAID status and replace failed disks) | ||
| - | |||
| - | If you feel like exploring different setups, go ahead. | ||
| - | |||
| - | As i said earlier, i have been using Linux software RAID implementation for more than one decade and i have never been let down. It's solid, it's simple, it works and it's efficient. If you choose to use a commercial external RAID solution, skip the RAID part ahead. I will assume you have two external drives called** /dev/sdb** and **/ | ||
| - | |||
| - | I will add some speed considerations: | ||
| - | |||
| - | ===== Partitioning ===== | ||
| - | |||
| - | |||
| - | ===== Creating the RAID array ===== | ||
| - | |||
| - | Then it's time to create the raid array: | ||
| - | |||
| - | > mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb1 /dev/sdc1 | ||
| - | |||
| - | ===== Format and mount ===== | ||
| - | |||
| - | format it, and mount it as /data: | ||
| - | |||
| - | > mkfs.ext4 /dev/md0 | ||
| - | > mkdir /data | ||
| - | > mount /dev/md0 /data | ||
| - | |||
| - | /data will be the entry point for your media collection. You will also store all the temporary files and executables for the various software stack that we will be using. | ||
| - | |||
| - | Your raid needs to be automatically mounted at every boot, so you need to add a line like this to /etc/fstab: | ||
| - | |||
| - | / | ||
| - | |||
| - | (the noatime option will reduce USB traffic and wear-and-tear. You might want a different filesystem maybe, do your own research) | ||
| - | |||
| - | ===== Automate RAID at boot ===== | ||
| - | |||
| - | You also want to automate linux raid startup: | ||
| - | |||
| - | > rc-update add mdraid boot | ||
| - | |||
| - | and, maybe, you need to ensure the md0 device doesnt change name upon reboot (it happened to me sometimes), so put this line into your / | ||
| - | |||
| - | ARRAY /dev/md0 UUID=1758bcfa: | ||
| - | |||
| - | where the UUID can be read by the output of the command: | ||
| - | |||
| - | > mdadm -detail /dev/md0 | ||
| - | |||
| - | Using the UUID ensures that even if your USB ports get shuffled around (and it happens, specially if you unplug/ | ||
| - | |||
| - | ===== Prepare the disk for the media collection ===== | ||
| - | |||
| - | You need to create the individual collections entry points like: | ||
| - | |||
| - | > mkdir /data/Films | ||
| - | > mkdir /data/Tv | ||
| - | > mkdir /data/Music | ||
| - | > mkdir /data/Books | ||
| - | > mkdir / | ||
| - | |||
| - | The last one will not contain actual media, but it will be used to store the installation (or the cache folders) for the various softwares described in this page. | ||
| - | |||
| - | Ok, all done? Go to networking setup... | ||
