Raid 6 Amateur File Server Setup Questions
-
Wow - nice huge post - welcome to ML.

How are you accessing these files? Just using Windows SMB file sharing? You specifically mention there is no other software installed in the OS, so I was assuming it must just be SMB file sharing.
With that in mind, Why pay the Windows tax? Why not install Linux? It's free, requires less system resources, etc.
- I'd personally go with XenServer and then a Linux distro in a VM assuming you can make partitions large enough to handle your file needs
2)The RAID controller is a typical server component, they are designed to run 24/7. Cooling will be your biggest issue here, noise being the second, and power draw the third. Other than saving money on power and your hearing, I see no reason to shut it down.
3)There is no reason to split the OS away from the array - you're wasting drive slots/storage/performance by doing so. As mentioned in #1, I'd install XS on a SD card or USB flash drive, then built a VM for the OS. The VM should have it's own partition for the OS, then a separate partition for the data drive.
4)I agree - you should have both. - because your files are larger, a larger stripe size is fine. 4K seems typical today.
- Quick Init is fine.
- yep, just use the default of the OS you're using - performance isn't critical it seems, so no point in trying to do anything fancy.
8)Well, by default Windows 10 goes into power save mode - though I don't know after what period. I also don't believe it will wake from normal traffic requests, so a WOL would be required or a manual wake up (press power button, etc) - Anything you missed? So you're starting with a 4 drive RAID 6 setup, but you plan to add 6-8 more disks down the road. hmmm.. .@scottalanmiller ?
- No I wouldn't try testing the rebuild, undue, worthless stress on the system.
- RTM (read the manual) - sorry I have no idea.
- I would only grow it once, but frankly, not a fan of growing it at all - and a question, can you add 6-8 disks to a pre existing RAID 6 array all at once? ages ago I could add disks to a RAID 5, but only one at a time. So if I was adding 6 disks, that was 6 different rebuild processes - that's a no go in my book. backup your data and rebuild the array and start over.
12a) what is Utilize the savings of RAID6 over a backup Please Please Please understand that RAID 6 is NOT a backup, not even close! If the RAID array had a URE (Unrecoverable Read Error), the whole array is toast and your data with it. RAID 6 does allow you to loose two drives and yet still have a viable system, but again this is not a backup. If you don't want to have to rerip all the movies, etc, you need to have an actual backup solution for this array. -
- is this still an issue? @scottalanmiller

With that size I would seriously consider using software raid. Something like CentOS w/ ZFS using Striped Mirrored Vdev’s (essentially Raid 10).

I questioned choice of Windows on spiceworks, and his reply was that he was more familiar with it. However, using client OS for server role is just silly - I doubt $800 windows server license is in play here.

In my opinion your considerations should really be these (in order of importance):
- What is the absolute best software or product for my situation?
- What is the cost? Can I pay it? Etc.
Your knowledge shouldn't enter the equation as you would benefit from learning new technologies. Linux specifically is extremely cost effective in a myriad of ways often times with a performance increase. I myself am a newer Linux user and have learned quite a lot from tinkering with some of the guides here. My home server and all PC's with the exception of my gaming PC are all on Linux now.

Certainly at least one familiar face, thanks indeed for linking to my original thread;) I am here due to recommendation from SAM (since I couldn't post without moderation over at spiceworks).
I got a free Win10 via an upgrade from 7, hence no Windows tax (well, you know, having paid for it at some point of course but not now).
Your guess regarding SMB is correct, that is indeed how I have been accessing the files via Kodi so far.I do not insinst on Windows if there is a good reason for not using it, at all. I know it's not the best OS by far, although for my normal usage it kind of is (Office Suite, few decoding tools, some Games); but that's not on the server, of course. I wouldn't have bought a licence though.

As far as growth goes it really depends on the technology used. ZFS uses pooling which handles throughput on a pool level. This was my considering when building my media server/test environment. I invested in 32 TB of space right off the top for that reason.

Why when there is a hardware raid controller would you effectively downgrade to software raid? Unless there are limitations on the card (like a number of supported drives or something)

Would you be willing to switch to Plex server instead of Kodi? I haven't used Kodi personally, I have Kodi client box at home with Plex plugin, to access Plex server. Plex opens up a lot more possibilities, both client side and server side. The only possible downside is server side transcoding, stronger CPU is required to handle that smoothly.
-
The growth question is not that important at the moment though. I will start with 6x3TB, but if I could build another array later on the same controller (with, say, 6-8 x 4-6TB drives) that would also be fine.
That it is not a backup, I am aware of. My plan is to, should one drive fail, buy more drives, backup the data and then attempt a rebuild. I haven't seen a drive failure yet (my oldest HDD that I still use is probably around 7 years and 13yrs for an external), but I am only a home user, so I am sure it will happen eventually. -
I was thinking to eventually add Plex somewhere down the line. Right now both my media pc and work pc are much more powerful than the server.
The server is based on the AM1 platform, I just switched out the terrible 2650 (2x1.45) for a slighlty better 5150 (4x1.60). Should be ok for x264, yet I don't know about x265 and whatever may come.
Building my Kodi library has taken a while do, I'd assume the same process would wait for me with Plex (with foreign language movies not being scrubbed correctly from databases, etc...) -

I think Raid Controllers are a waste of money unless you absolutely have to use windows in which case you have no other good choice. They don't make the raid controller listed anymore so if that thing breaks hes going to lose all of his data. You have to install the exact same raid controller with the exact same firmware for that to work too. With software raid you don't have to deal with that headache and the overhead on the processor is almost non-existent in the modern day.

Thanks a lot for the warm welcome.
And also for the incredibly fast respones. I'm quite amazed, really. I wish I could give something back. -

So the thing with Windows is, beyond it being really expensive, is that its software RAID is kinda craptastic. Software RAID on its own is great, as a concept. And there are great implementations of it like MD RAID (from Linux) and ZFS (from Solaris and FreeBSD.) For home use, whatever, Windows is just fine. But it's also not free. Using Linux with MD or FreeBSD with ZFS would give you a really good software RAID option that Windows does not.
Linux or FreeBSD are also generally considered much better for use as a media server.

I just bought the RAID controller, new not used. I'll have to keep an eye on its availability though, but right now it's still being sold by a couple of shops.

The key benefit (other than fixing a Windows deficiency of course) is that good hardware RAID offers blind swap. That's not a trivial feature.
