Хочу понять есть ли RAID или нет.
Первая машина
cat /proc/mdstat

Вторая машина
fdisk -l
Disk /dev/sda: 149.1 GiB, 160041885696 bytes, 312581808 sectors

sudo cat /proc/mdstat
cat: /proc/mdstat: No such file or directory
Третья машина
cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [multipath] [faulty]
md2 : active raid1 sdb2[1] sda2[0]
523200 blocks [2/2] [UU]
md3 : active raid1 sdb3[1] sda3[0]
1952461760 blocks [2/2] [UU]
bitmap: 7/15 pages [28KB], 65536KB chunk
Это значит что на 1 и второй машине нет RAID, а на третьей есть RAID1?
Если нет, стоит ли делать его?
