Well, they're focusing on removing it!

D. Ebdrup posted:Non- Looks like RAID-Z expansion is still in detail design and Ahrens really isn't expecting decent-quality code until 2018. It's pretty neat what they're doing: it looks like they're monkeying with the spacemap to rebalance all the blocks. Improved scrub and resilver appear to be coming to upstream relatively soon. The improved deduplication proposal looks nice but it still requires huge amounts of memory for the in-memory deduplication table ![]() Changing ashift on a live pool looks kind of ugly under the hood: there's quite a bit of penalty involved so far. It's better than "well I built the pool with 512n drives and all I can get are 4K drives now, the only thing I can do is make a new zpool" but not something one really wants to do right now ...

What's my cheapest decent option for a 4-port SATA or SAS IT/JBOD card?

All the consumer grade cards I see are just slapped together with either a Marvell or Silicon Image controller and I couldn't name you a good one by name. I don't even think Startech, which is maybe the one company I can think of, even has a 4 port card that's inexpensive.

More or less you're looking for an LSI 9211 card with 4-8 ports. The aforementioned M1015 is rebadge of the LSI card and can be firmware flashed to IT mode. There are also other cards out there that are rebadged 9211s like the Dell H310. The 9211 comes in a 4-port variety that is often less than $50 used on EBay. Might as well spring for the 8-port version to give yourself some future proofness though.

Ehhh I think I'm going to go back to 6/iR in my 720 because I need all the other PCIe slots. Need one for external HBA, one for 10GB, and my SATA/SSD internal enclosure takes one but is 2 slots tall. I could theoretically keep using the card I flashed to IT and put the SSD into a caddy in my MD1200 but that means I'd have to run the MD1200 which means I'd probably want to mod the fans to run quieter which is a project in itself. If I want to swap out HBAs (6/iR in IT mode to stock 6/iR), should that be fairly transparent to FreeNAS? Would it be as easy as just importing the drives or would it just boot up with the new controller and auto-detect the array through ZFS magic?

Does anybody have first hand experience with ironwolf pros? One of my usual web stores is running a campaign for 4tb units at roughly the same price for 4tb standard reds. Are they time bombs? Are they slow and noisy?

Are they time bombs? Are they slow and noisy? I've been running a few of the 10tb Ironwolf Pros for archiving video and other work. Speed is what I expect from a hard drive, which is pretty slow, and they're honestly no noisier than other high capacity drives I've used from Toshiba and Western Digital. Which is pretty noisy during load but not intolerable. I don't expect the 4tb drive to be all that different from other 4tb drives in its class. I can tell you about the warranty service they brag about though. When one of my drives died in about a week (probably because it was shipped inadequately), I sent it to Seagate Australia to let them recover data on that drive. Two weeks later, they sent me a replacement 10tb drive and my recovered data on a 4tb Backup Plus (which I assume they're letting me keep). Its honestly a pretty neat warranty service, especially if you can get these drives for a low price.

I had 100% failures across five Ironwolf NAS drives from two separate manufacturing batches.

Seagate claims 20TB HAMR drives will be mass-market in 2019. Guess it's time to start saving my pennies. I'll be very interested to see if they make them their new mainline since their blog post about it seems so optimistic. If they do that, there's a very real chance we could see lower capacity HAMR drives that just replace the stuff that's mainline right now, which should run significantly cooler because there'll be less platters.

It'll be interesting to see how the next major recording technologies play out. I don't think WD has cut bait on HAMR yet, but the industry's been working on it for about a decade now with still no tangible results. Just a few weeks ago WD made it sound like they're now pushing all of their chips into MAMR, which should be shipping in 2019 as well.

Yep, those are awesome. I've got 8 of them in the NAS a few feet from me right now. Most of the time, they're pretty quiet, and they don't run terribly hot. They're really easy to shuck too.

Yeah, seconded - I have been running 3 as a software RAID5 in my home server for the past month or so and they've been flawless. Shucking all three was pretty quick with a set of guitar picks to pry the tabs open. The drives inside were completely standard 8TB Reds, same label as the bare version. Even in a crowded microATX case with only one slow exhaust fan they stayed under 50C, and now that I've added an intake at the front they top out around 42.

Check the model number on bottom of box before you buy, next to the barcode MGBJRCK = 256MB Cache MGBJRCJ = 256MB Cache LGBJRCK = 128MB Cache Model WD80EFAX drives are Thailand made with 256MB of cache. Model WD80EFZX drives are China made with 128MB of cache.

Decairn posted:Check the model number on bottom of box before you buy, next to the barcode Yeah I verified MGBJRCK and WD80EFAX before I bought them. Just picked up 2. Will run as regular externals until I figure out if I want more and go back to a NAS setup for my HTPC media. Not super concerned about backing up this stuff, just needed more storage as my little 4x 3TB NAS is full and only supports 4TB drives. The cost to upgrade to 4TB in the NAS vs picking up a few of these and in turn selling the NAS made switching to externals an easy choice.

And I just came home with one not 20 mins ago, read this, and its the 128MB version. ![]() TBH if this drive passes preclear tests I dont care. Its my "the apartment burned down/its all stolen" contingency drive I'll be leaving in a drawer at work for stuff I dont feel like backing up to the cloud.

I mean, how much real world difference is there going to be between the two? Given a choice I'll always take more cache but I wouldn't expect it to be meaningful in a home environment, doubly so when stuck in a ZFS array with lots of RAM.
|
![]() |

I mean, what other 8TB hard drive are you going to get? That's what I was trying to get at earlier. Sure, get the one with the bigger cache if you have a choice, but otherwise I think you're still coming out ahead.

So now that I've got these new 8TB drives I'm going to be selling my previous NAS. What's the best set of tools to use to check the drives and give relevant info to anyone who might want to buy them? They are 3TB WD Green drives if that helps any.

If you have a motherboard with IPMI graphics and you put a processor in it with an iGPU, can you pass that iGPU through to a guest VM? Is there any benefit to doing so for transcoding with Quicksync for Emby? Or is the quality not worth it? (I'm specifically thinking about Skylake or Kaby Lake here - I am aware there are some oddities with Haswell and needing a display attached before QuickSync will function) Is there any way for me as a single user to use Intel ME like an IPMI or serial terminal or something, such that I could avoid having to find an IPMI model? Or is all that locked to businesses with licenses/etc? Paul MaudDib fucked around with this message at 01:29 on Oct 31, 2017 |

One is the me will have a pretty basic web server that you can do power on/off, see some details of the hardware, etc. Then you can also get a ipmi-like remote kvm, software to access that is sort of hard to find. The company that makes real vnc has a viewer that works and there is also mesh commander.

VPRO can provide iKVM if you use the onboard graphics. You will need to initialize the mobo as a SMB setup with no authorization required to access(otherwise you will need to enter a pin from the computer you want to remote). Conventional ME won't. You need a motherboard with a q170 or q270 chipset and a non-k version of the processor you want to use.

Yes, I did this passthrough with Linux KVM and Plex. The encoding quality is visibly worse than software and not worth it because the processors can do much better at relatively low load. IMO Quicksync only makes sense for underpowered Celeron/Atom NAS boxes but I dont know how those will fare when h.265 becomes standard. My box came with Intel AMT and required no licenses to use.

I use the hardware encoding for live transcoding to a lower format over severely restrictive bandwidth (my data plan). Since Plex incorpreated it into the current version of Plex, I have started seeing less drops out or complaints of quality loss through the Plex mobile app.
