Successfully Made RAID 1 array in bios, (MSI 970A-G43) OMV detects the drives as single drive. To use RAID 1 OMV wants to create a software RAID1? Why does OMV detect two single drives?

Confusing. Does OMV show you one or two drives?

Hi macom,
OMV Shows 2 single drives, in BIOS the RAID1 array is okay. It seems that there is 1 array in BIOS and now i had to let OMV make a software array RAID1 for the same disks in order to use these 2 disks as one volume. I think that can't be right
-
So you see the two drives in "physical disks". Probably three in total: 2x data drives + system drive. Right?
-
That is correct, now OMV created a RAID1 array i see the disks as one volume, but that is not my issue i wonder why the hardware array in motherboards BIOS is not recognized by OMV
-
Sorry, I cannot help you with this one. Let's see if someone else has an idea.
-
You dont have hardware raid on this MB,this is fake(software) RAID.
-
Thanks, So i might just as well clear the RAID 1 in BIOS of the Motherboard?
-
Yes,it is recommended

Why do you want to use RAID1?

I had a RAID1 for some years, but realized then that I do not need availability.. What I want is to have my data secure. Problem with RAID1 is, that if you delete a file by accident, it will be shortly after deleted on the both disks. Same if malware is encrypting your samba share.
So I decided to get rid of the RAID1. Now I have one master data disk. On a regular basis I create snapshots of the data on a second disk using the rsnapshot plugin. Doing this I keep different versions of the files I have modified. If I delete a file by accident it will not be there in the last snapshot, but in the one before. So I will be able to restore the file from there. -
I like the thought of having a auto backup in case one drive is faulty. If for what reason a file is deleted by accident it still is available in the waste bin.

Addition: "it will be
shortly afterimmediately deleted on the both disks" - and RAID1 does not provide any integrity (checksum or XOR)!RAID1 is not recommended for data. Use ZFS, BTRFS or an one data-disk/one rsync-disk ... and of course a (external) backup!

RAID is not backup.
Backup is not RAID.
Trash/Waste/Recycle bin, is not backup.

This can get confusing because it could be doing a RAID1, but you would expect to only see one drive. It may in fact be doing a RAID1 but not hiding the other drive from you. This could cause you to be able to use both drives for different things. This would be bad.
The suggestion is to remove the motherboards RAID settings, make sure it's not doing anything. Delete the RAID set it created, if it actually created one. Then use OMV to RAID the drives together.
Remember, RAID1 is protecting uptime and availability. Backups protect data. That's a BIG difference and understanding that is important.

And does a great job in explaining RAID-1 totally wrong.
