I've not tried linux before, and a friend recommended using CentOS on the HP ProLiant MicroServer I just bought to play around with.
I managed (after a while I admit) to create a USB that was bootable with the installation files on, and installed it to that USB, also selecting a 250GB HDD as a system drive when going through the installation process.
I have 2 other HDDs in the server, both of them 2TB.
The issues I am facing at the moment mainly revolve around these ... I want to create a RAID1 with them both, however when I did this in the hardware (BIOS etc) it did not appear to work (Well it may have done, but it wasn't showing in the OS).
So I undid that, and in the "Disk Utility" in CentOS, I tried to create a raid 1 array, however it says there are insufficient number of disks for this type of array. I tried to format my two 2TB drives and it says they can not be formatted as they are 'busy'.
I've been searching the web for hours and am not able to find a solution to this issue, from what I can tell it knows they are there, but I can't access them etc through 'Computer' (where you'd normally find different drives on a Windows OS).
The Disk utility shows this kind of format:
SATA Host Adapter
250 GB HDD
2 TB HDD
2 TB HDD
PATA Host Adapter
54 GB HDD
10 GB HDD
2 TB HDD
185 GB HDD
Corsair Voyager (The USB the OS runs off)
When trying to create a raid array from the disk utility, only the 2TB HDD in the 'Peripheral Devices' is selectable ... and there's only one there even though there is two physical drives in the machine.
I'm not really sure what reports or info you need ... hopefully I've managed to explain my current situation and why I need help (getting it so the RAID works / drives are recognised).
My aim for this system is to attach it to the network so my family can use it to backup and store files in their own areas on the drives (which can not be accessed by anyone other than themselves and the superadmin), and also a web server area where I can test websites etc (I currently use XAMPP on my PC, but when I'm not at home, I can't access my machine unless it's turned on, so having this central device will be more ideal).
Thank you and sorry for being so newb!
