Answer / saurabh makkar

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
