How to create Raid 01 over loop devices

hii guys today we will learn how to create raid 01 on loop devises . if you want to know what is loop devises so click how to create loop in redhat linux . so here we will start loop over raid

at fast we will make two loop device a.txt, b.txt

[root@localhost ~]# touch a.txt
[root@localhost ~]# touch b.txt
[root@localhost ~]# touch c.txt
[root@localhost ~]# touch d.txt
[root@localhost ~]# touch e.txt
[root@localhost ~]# touch f.txt
[root@localhost ~]# touch g.txt

then we will provide txt file size blow this commands

[root@localhost ~]# dd if=/dev/sda of=a.txt bs=2M count=100
[root@localhost ~]# dd if=/dev/sda of=b.txt bs=2M count=100
[root@localhost ~]# dd if=/dev/sda of=c.txt bs=2M count=100
[root@localhost ~]# dd if=/dev/sda of=d.txt bs=2M count=100
[root@localhost ~]# dd if=/dev/sda of=e.txt bs=2M count=100
[root@localhost ~]# dd if=/dev/sda of=f.txt bs=2M count=100
[root@localhost ~]# dd if=/dev/sda of=g.txt bs=2M count=100
[root@localhost ~]# dd if=/dev/sda of=h.txt bs=2M count=100

here our every file size is 200MB now we convert in loop devices blow commands
[root@localhost ~]# losetup /dev/loop0  a.txt
[root@localhost ~]# losetup /dev/loop1  b.txt
[root@localhost ~]# losetup /dev/loop2  c.txt
[root@localhost ~]# losetup /dev/loop3  d.txt
[root@localhost ~]# losetup /dev/loop4  e.txt
[root@localhost ~]# losetup /dev/loop5  f.txt
[root@localhost ~]# losetup /dev/loop6  g.txt
[root@localhost ~]# losetup /dev/loop7  h.txt Continue reading
