CLOSED: Adding a RAID 1 disk pair in HP Proliant Microserver Gen8

[ghrasko]

Hi,

I am looking for information about additional HDD installation in my HP Gen8 server running Amahi on Fedora 21. I am beginner in both Linux and Gen8. I checked a related topic, but it seems it is not totally suited to my requirements.

I installed Amahi on a HP Proliant Microserver Gen8 successfully. It is a single 3TB HDD install at the moment with all necessary partitions and mounts. I copied all files from my earlier Zyxel NSA325v2 2TB HDDs (RAID1) to this single HDD (and made another backup copy as well) under /homes partition. To be able to boot the system correctly, I had to switch to AHCI support in the HW BIOS.

Now I would like to add the HDD pair from the old NAS to this new hardware with Amahi. The final goal would be to use the 2 HDDs in RAID 1 setup for the most vulnerable data and use the already installed single HDD as system disk and for not so sensitive data. I am not using Greyhole and possibly I don't have to. I am not expecting to save the data on the 2 old HDDs.

What is the general procedure in this case? Should I configure the two disks, the RAID 1 configuration outside of Amahi on the Fedora (or HW) level? What should I do in Amahi after that? And by the way how it should be done in Fedora? All 3 HDDs are WD Red NAS disks.

As I wrote, I am not a HW expert. I am reading the information on the internet and I just realize that RAID 1 will not fit my "backup" requirements. It is good for improving performance or reliability, but is not reliable as a backup (of each other). If the controller hardware fails, I am in deep trouble, unless I find a rather similar HS environment.

If this is true, what should be my best starategy with HP Gen8, Amahi and the 3 HDDs if data backup is more important then performance or operational safety (continuity)?

Should it be Geyhole?

I personally would recommend using Greyhole. It does the job without the complications of RAID for file redundancy.

Thanks for the reply. I accepted your recommendation and went for Greyhole.

Hope it works out for you as expected.
