Hello,
I do use FreeNAS for my Media Storage Server for Years now and although its an not supported configuration (Virtualized using KVM) it has been working great.
However I run out of space.
My current setup is as following:
6x SATA from Chipset (the whole controller is passthrough to FreeNAS, 4xSATA of the CPU is used for the VM host), i.e. direct hardware access.
8x SATA from a LSI SAS 9207-8i (also passed through)
Connected to it are
4x WD Green 4TB (Chipset)
2x Seagate NAS ST8000VN0002 8TB (Chipset)
2x TOSHIBA HDWN180 8TB (LSI)
They form 4 RAID 1 a 2 Disks.
As you can clearly see from the various disktypes, the server grew over the time.
So while RAID 1 worked great from me so far, it is mainly a relict of me not knowing what I do when I started out.
RAID Z1/Z2 have a better fault tollerance even with 4 disks and I should have started with it from the beginning.
Since I now run out of space AGAIN I'd like to change that.
The question is how.
What can I do to get the most space at a reasonable price (<1000€) while also moving from RAID 1 to something more secure.
RAID Z1 is not an option since its pretty much RAID 5 which tops out at 4TB disks doesn't it ?
So I would need to do RAID Z2.
One idea I had is as follows:
Toshiba Enterprise Capacity MG08ACA 16TB is quite cheap right now (~430€).
I could add 4 of them to my system in a RAID Z2 which would give me 32TB new space. Then I can copy all data from my array over and reconfigure both my 4 4TB, and my 4 8TB once to RAID Z2 after which I have 3xRAIDZ2 with a total of 56TB usable space. The ratio between drives and storage is as good (or bad) as before but now I have better redundancy.
However this solution is quite expensive (~1300€).
Is there a better solution I am missing ?
