debian Debian Raid Help Me

[filsdemorte]

I am very stumped regarding why I can configure a hardware raid and not have it show up in my console, and if I try to get it to show up, I f**k it up even worse.

I am new to Debian and Linux as a whole. It has been a complete upwards curve for me as far as learning all the commands and downloading millions of packages.

 

My Server is a SuperMicro 5017C-MTF

The motherboard is a Super X9SCL-F with a Xeon E3-1220V2 and running with 16GB ram

 

I have used the hardware raid controller that is built into the server, the 4 drives are set up in a raid 5.

I'm having problems being able to mount them in Debian. 

 

Here is my version information if this is needed 

Distributor ID:    Debian
Description:    Debian GNU/Linux 9.9 (stretch)
Release:    9.9
Codename:    stretch
 

 

Below is the information I have regarding my hardware controllers and drives

I tried initializing and setting up SDA as a gpt drive since they aren't mounted or initialized. What that did was break my raid. I don't know what I should be doing. 

I have been reading everywhere and all it is doing is stumping me.

 

If I need to, I can also upload dmesg. 

 

My other question is, my /ect/fstab directory is unconfigured and barren. 

I must be sounding like an idiot, can anyone explain to me what I need to be doing to make this work?

So, I am a huge noob as well lol. But, I do know a few things that maybe at least could be useful? Maybe? Depends on the situation tho.

 

A) I wouldn't use hardware RAID if you can avoid it, software raid is more robust. ZFS is amazing, but you would have to do a bunch of work to get that working, its not out of the box. I use freenas for that reason, but this may be beyond your needs and use case. Also, same sort of vein, the good ol "RAID 5 is dead" saying. Its just not enough redundancy these days. Granted, 4 1 TB drives are not huge, so statistically speaking your better off, but still, just figured I would say it...

 

B) I can't help you with the why its not showing up in debian, but I do use fstab on my VM's (I run freenas and some unbutu VM's under ESXi, but, like, I am NO Linux guru at all lol). But for my use.... fstab is just a Samba mount. I don't think you would need that in this config? You are trying to connect bare metal... In my use case I have fstab entries to connect an ubuntu server instance over a virtual network connection (via ESXi) to the freenas SMB shares I have.

 

Thats.... about all I can say. Hopefully something in there helps lol

You don't have a raid controller, you have the intel fakeraid, you dont' want to use that.

 

WHy not just use md or zfs or btrfs to make a software raid, its much better here.More features and faster. If you want hardware raid, get a real hardware raid card, like the ones from lsi.
