There are many FOSS frameworks for managing disks and accessing remote file systems via NFS and Samba. These include FreeNAS and Open Media Vault (OVM). However, this document describes the low-level view when using Software Redundant Array of Independent/Inexpensive Disks (RAID) via mdadm.
RAID is not a backup. Data on the disks used in this document will be erased.
aptitude install mdadmObviously you need at least two disks for RAID 0.
Use fdisk or your tool of choice to partition the HDD.
As root
mdadm --create --verbose /dev/md0 --level=0 --raid-devices=2 /dev/sda1 /dev/sdb1
mkdir /mnt/raid0
mkfs.xfs /dev/md0 # Or your filesystem of choice
mount /dev/md0 /mnt/raid0mdadm --detail /dev/md0Edit /etc/fstab
/dev/md0 /mnt/raid0 xfs defaults,noatime 0 1Add configuration to mdadm
mdadm --detail --scan | tee -a /etc/mdadm/mdadm.confCheck if the configuration is OK.
rebootVerify that the RAID comes up.
Obviously you need also at least two disks for RAID 1. The process is basically the same as for RAID 0. Here the summary:
Use fdisk or your tool of choice to partition the HDD.
As root
mdadm --create --verbose /dev/md0 --level=1 --raid-devices=2 /dev/sda1 /dev/sdb1
mkdir /mnt/raid1
mkfs.xfs /dev/md0 # Or your filesystem of choice
mount /dev/md0 /mnt/raid1mdadm --deatil /dev/md0Edit /etc/fstab
/dev/md0 /mnt/raid1 xfs defaults,noatime 0 1Add configuration to mdadm
mdadm --detail --scan | tee -a /etc/mdadm/mdadm.confCheck if the configuration is OK.
rebootVerify that the RAID comes up.
