Как я могу проверить, есть ли на моем сервере RAID-1?

С помощью команды lsblk я получаю:

NAME    MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda       8:0    0 232.9G  0 disk
├─sda1    8:1    0    32G  0 part
│ └─md0   9:0    0    32G  0 raid1 [SWAP]
├─sda2    8:2    0   512M  0 part
│ └─md1   9:1    0 511.4M  0 raid1 /boot
└─sda3    8:3    0 200.4G  0 part
  └─md2   9:2    0 200.3G  0 raid1 /
sdb       8:16   0 232.9G  0 disk
├─sdb1    8:17   0    32G  0 part
│ └─md0   9:0    0    32G  0 raid1 [SWAP]
├─sdb2    8:18   0   512M  0 part
│ └─md1   9:1    0 511.4M  0 raid1 /boot
└─sdb3    8:19   0 200.4G  0 part
  └─md2   9:2    0 200.3G  0 raid1 /

С помощью cat / proc / mdstat получаю:
