With lsblk command I get: 

NAME    MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda       8:0    0 232.9G  0 disk
├─sda1    8:1    0    32G  0 part

└─sda3    8:3    0 200.4G  0 part
  └─md2   9:2    0 200.3G  0 raid1 /
sdb       8:16   0 232.9G  0 disk

└─sdb3    8:19   0 200.4G  0 part
  └─md2   9:2    0 200.3G  0 raid1 /

With cat /proc/mdstat get:

Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md2 : active raid1 sda3[0] sdb3[1]

The /proc/mdstat output is very clear: you are using RAID1. You have three software RAID1 arrays, to be more precise.

  • Thank you. How can I check the free space of sda and the free space of sdb? – Panagiotis Koursaris Feb 12 '16 at 14:22

    If you are referring to non-partitioned space inside your disks, from `lsbck` it seems that you have **no** free spece. If you mean the free space of your filesystem (on top of the RAID1 array), simply issue `df -h` and read the output. – shodanshok Feb 12 '16 at 14:24
