0 root@bigpuff:/home/raidtest# cat /proc/mdstat
Personalities : [raid10]
md0 : active raid10 loop3[3] loop2[2] loop1[1] loop0[0]
203776 blocks super 1.2 512K chunks 2 near-copies [4/4] [UUUU]
unused devices: <none>
0 root@bigpuff:/home/raidtest# mdadm /dev/md0 --grow --level 0
mdadm: level of /dev/md0 changed to raid0
0 root@bigpuff:/home/raidtest# cat /proc/mdstat
