RAID10 can be implemented by first implement RAID1(ie mirring) then implementing RAID0(stripe set on different disks) on it.

Configuring RAID10
Step1:Get the info who many devices are participating, for example here we taken 4 disks(/dev/sda1,/dev/sdb1,/dev/sdc1,/dev/sdd1).
Step2:Implement RAID1 on four drives(taking 2 each)
#mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sd[ab]1
#mdadm --create /dev/md1 --level=1 --raid-devices=2 /dev/sd[cd]1
Step3:Now implement RAID0 on two of RAID1 devices(/dev/md0,/dev/md1)


#mdadm --create /dev/md2 --chunk=64 --level=0 --raid-devices=2 /dev/md[01]
Step4:Format the RAID10 device with ext3 and mount the device

#mke2fs -j /dev/md2
#mkdir /store
#mount /dev/md2 /store
Unconfiguring RAID10
Step1:Unmount the RAID device /dev/md2

#umount /dev/md2 or #umount /store
Step2:Stop the RAID device

#mdadm --manage /dev/md2 --stop
#mdadm --manage /dev/md1 --stop
#mdadm --manage /dev/md0 --stop
Step3:Remove the Disks(/dev/sda1,/dev/sdb1,/dev/sdc1,/dev/sdd1) by using fdisk utility
