[Bug 1477347] Re: Output from iostat has the total read and total write columns backwards in Ubuntu 14.04

[bdwongsson]

Probably want to see an example:

Here are the contents of /proc/mdstat showing my RAID setup:

~$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md0 : active raid10 sde1[3] sdd1[2] sdc1[1] sda1[0]
      976507904 blocks super 1.2 512K chunks 2 near-copies [4/4] [UUUU]

unused devices: <none>

Here is the output from iostat:

In this case sda,sdc,sdd, and sde are the raid
