How To Set Up Software RAID1 On A Running System Debian Stretch (minimac 2010)

I want to use a Mac mini 2010 server with ISPconfig, I looking for a way to setup Debian Stretch with Raid 1 configuration.
How to setup Software RAID1 On A Running System Debian Stretch (minimac 2010)
I can find only for Debian Squeeze, is this for Stretch the same ?

Thanks

 

Why Debian Stretch and not the current version Buster?
I expect the RAID setup is similar in recent versions of Debian, so use documentation, for example https://wiki.debian.org/SoftwareRAID .

 

Hi, thanks for the info. I use Debian Stretch because there isn't a automated installation for version Buster.
I will try the example link for the Raid 1 setup.
I had used "To Set Up Software RAID1 On A running System" but no succes.

 

Hi, i installed Debian 9 Raid 1 on my minimac 2010 with the Debian installer.
But there is an issue with md2 [_U]
How to solve this problem, is there something wrong with the raid configuration
or something else ? I use 2 brand new HDD 500 Gb drives, so I suppose there are no problems with the drives.

Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md0 : active raid1 sda2[0] sdb2[1]
483801088 blocks super 1.2 [2/2] [UU]
bitmap: 1/4 pages [4KB], 65536KB chunk

md2 : active raid1 sdb3[1]
3926016 blocks super 1.2 [2/1] [_U]
