Hi for creating Raid5, first u need to create a 3
Partitions. Because 3 partitions is required for
implementing Raid5.
Step1:- Creating partions, so the command is
#fdisk /dev/hda or #fdisk /dev/sda
where hda = If HDD is IDE, sda = If HDD is SATA.
with the help of above command we create 3 partitions.
Step2:- To add above 3 partitions for activate RAID5
#mdadm -C /dev/md0 -n 3 -l 5 /dev/sda{10,11,12}
or
#mdadm -C /dev/md0 -n 3 -l 5 /dev/hda{10,11,12}
Where C= for Create
10,11,12 = Partition ID
Step3:- Format the raid or Multiple Devices
#mkfs.ext3 /dev/md0
Step4:- After formatting craete a Directory where you want
mount to above Multiple partitions
#mkdir /storage
#mount /dev/md0 /storage
