Thank you sir. I am not a huge fan of XFS because I can never find drivers.. but as you said, you don't need to worry about it. BTRFS would be nice. Checking out the vid though.

I've been using unraid for a little over a year, it just works is the easiest way to sell it to people. There is a ton you can do with it though.

I refuse to use RAID 5'ish things. This seems like a great compromise between logical RAID like WHS/Stablebit Drivepool and RAID 5/6. For backups, nothing like a HD unplugged in a drawer somewhere else.

There's a trial mode for 2 weeks so it can't hurt to try it out. My advice is to preclear your drives ahead of time if you can.

My brother in law asked me about a NAS for storage and running Plex. It's been awhile since I looked into self-contained stuff. I'm guessing a QNAP or Synology but not sure which ones to look at. Suggestions?

That seems like a good thing. You can run without a parity drive if you're just trying it out. And yes, preclear is a stress test format that unraid runs when you first put in a drive. I believe there is a fast mode too. It took about 24 hours to preclear a 6 tb red for me. Don't do this on SSDs.

Speaking of implementations, isn't Stablebit Drivepool just SPAN/drive concatenation with optional per-folder mirror/stripe+parity?Matt Zerella posted:Also no drama.

An E3-1220v6 is basically an i5 7400, and the Atom 3958 should be close to twice as fast as that in multi-threaded performance. Granted, it spreads that power across 16 cores instead of 4, so single-threaded performance is about half of a 3 GHz Skylake.

Intel has multiple lines of atom processors, they are a clusterfuck to identify if you don't know the cpu target. C-series are meant for network appliances(routers or nas) and they can offload the network load to the onboard network core so they won't break a sweat handling 10g ports.

Oh, so there aren't any benchmarks that compare that Atom to its bigger brothers? It's fine if Atom comes out as being 50% slower than X since given its TDP and/or price it may still be worth it.

Man I've gotta post my experience with Unraid. It is absolutely amazing with its app store (unofficial), KVM support, and Docker support. I've been able to take my gaming PC and just make it a great server while using the video card pass-through to keep the machine relevant for the rest of my usage. It has basically been my entire home lab, NAS, and Gamestream system for around 6 months now. Basically the only thing it's missing is disk encryption, and that's been added to one of the new RC versions. Data fidelity isn't hugely important to me since I'm basically just using it for Plex, roms, etc. Anything important is on Dropbox. Organizr ![]() All of the above are setup with Docker, which auto-updates the images when the Docker repository does so. I had tried running all of the above software on Windows, and it sucked messing with NSSM and everything installing in the appdata folder, etc. VMs: ![]() As someone who used to dual boot and hated it, the virtualization support is awesome. The guide for doing a Hackintosh install on my laptop or to the bare metal of the server was more difficult than just creating a VM. High Sierra was still a bitch to get working, but now that it does it's nearly as good as a bare metal install since the graphics card again supports pass-through. All-in-all I just wanted to chime in that anyone looking for a good NAS with downloading and seeding capability who already has a solid gaming machine should consider Unraid (or a similarly capable software). I really didn't want to spend a ton on a dedicated NAS with HEVC/multiple stream transcoding capability, so this really worked out. My biggest gripe is it can be difficult to fix a problem when one comes up, and that you can't easily clone a VM. Luckily there's a big community who probably already ran into X problem and their SEO on their forum is pretty good so finding an answer isn't too bad. So just a heads up for anyone who was in a similar situation - trying not to spend a monthly subscription for downloader capability, or a (for me) fortune on a NAS with a decent CPU. My wife is now using a chromebook as a thin client for the High Sierra instance and she's not very into technical stuff - it's working great for her. If I were building from scratch I would likely go with a high core/threaded CPU like a Xeon however. edit: aaand all of this was basically covered in the past page. Oh well.

If I were building from scratch I would likely go with a high core/threaded CPU like a Xeon however. I've been trying to work out the same kind of build. The problem IMO is that E5s/HEDTs have a pretty high platform power consumption even at idle. My E5-1650 system (HP Z420) pulls 170w at the desktop and that's roughly what I get on my 5820K system too. Ryzen is actually the same way (and pulls roughly as much power as Haswell-E across the board). With my 16c/kWh electricity that translates into $20/mo just idling the machine, and even if you don't care about the cost that's an awful lot of heat to be dumping right into your drives. E3/consumer systems have much better idle power consumption. Kaby and Skylake Pentiums and i3s actually support ECC so for now I am doing that, and if 2C4T ever becomes an issue I can swap to a 4C8T Xeon relatively cheaply, or just add a second application server in a separate mITX case (doesn't really need ECC, so it could just be an 8700 or whatever). (if you think you're going to need that much horsepower, $900 for a high-end Denverton doesn't seem like a bad deal vs two separate systems, and it has really nice power consumption, but you will probably need to replace the passive cooler) Paul MaudDib fucked around with this message at 21:30 on Dec 11, 2017 |

Paul MaudDib posted:I've been trying to work out the same kind of build. Yes I'm currently using a 4790k in there, and the power consumption is much less than a Xeon for sure. The biggest reason I would consider moving to a server cpu is because I share my plex instance with a few members of my extended family, and it seems like they have to transcode everything which eats up RAM and creates a high load on the CPU - enough that I can't get a VM to run if a single 4k stream is being transcoded. For this particular usage case it may make sense, or if I was using the VMs concurrently which just isn't necessary for me at the moment. But yeah my CPU knowledge isn't that great; I only pay attention when I'm buying so I'm a couple generations behind on knowledge at the moment.

I have a Fractal Define R5 now with 6 Reds in it. I want to add 10 more to the NAS but I'm not sure in what fashion exactly. Basically I have a with Xeon with 32 gigs memory that boots ESXI, passes-thru an LSI controller & 16 gigs to FreeNAS, then uses the other 16 to run a bunch of VMs. The reds are 4TB in ZFS/Z2. So 16 usable and it's almost full I got 10 8TBs that i'd add to again as /Z2 for another 64 usable. I've had that for the past 3 years but now I see most of my workload is Docker containers. So I could grab a new case + mobo for the 16 Freenas drives and leave the define just for one docker machine. Or I could see about more storage in the define I think you can put a 2nd 5 drive caddy in there right? Or I could just give the NAS machine to my wife and move everything to something like a Dell R710 with 192gigs memory you can get on EBay fairly cheaply. EDIT Looks like I have the 9X0 and the 7X0 confused, the 710s are dirt cheap but can't handle 16 drives the 910s are big bucks but 4U. Anyone have thoughts?

Rsync/FreeNAS question: So I've managed to somehow get Rsync to work over SSH from a Win10 client (PUSH) with the ubuntu subsystem thing and to my FreeNAS (pull). But now I want to get it to work with SSH keys so I can let it run periodically without human input (entering a password). Something very dumb that i fundamentally don't understand is: does the username on the client (push), ie the name i use on my win10 bash, have to be the same as the user account on FreeNAS that is the recipient of the Rsync SSH command? Cause when I generate the SSH key pair on my client machine, its generated under the name of my Win10 user Like as it works now, with PW, i do rsync -rht --progress /mnt/c/Documents/ freenastest@192.168.1.161:/mnt/zfs_1/testshare/ i am asked to enter the PW for freenastest, which is an account I created on FreeNAS. but my account on Win10 is my name, not 'freenastest', so when I generate my SSH keys, there are not for 'freenastest' I pasted the public key into 'freenastest's public ssh key box in the freenas web ui anyways, and predictably it did not work. I feel like im doing a terrible job of explaining this. How do i force Rsync to try to authenticate using the private key stored on my Win10 machine, even though the username is different than the one i am using to SSH into the FreeNAS box?

Logging in as freenastest@server.com, from an bash account called myname@mywindowspc, will it check for the key in freenastest's home folder, or myname's home folder (which does not exist on freenass)? edit: checked "~/.ssh/authorized keys" for freenastest and indeed my pub key is in there, but it ends in "mywinname@mywincomputer", does that actually effect its "lookup" of the key? i guess it just seems like when I try to SSH into freenass, its not even looking at authorized keys, it just automatically asks me for the password. IS there a command in SSH (and rsync) that tells it like "hey, this is my private key, see if you have the pubkey"? Gozinbulx fucked around with this message at 21:14 on Dec 12, 2017 |

That ssh comment field is purely optional and is not part of the authentication process. You can tell your ssh client to use a specific private key to connect with. Also, if your permissions on the key on the client are too loose (needs to be something like 600 for your keys) you may see an error as you connect. Just turn on -vv options as you connect and youll learn more about what ssh does than youve wanted to know unless youre literally a cryptologist. You may also want to peek into sshd / security logs on the server for clues.

No, the bit at the end is essentially a comment field. It sounds like your SSH client doesn't actually have your private key, or it isn't activated, or something.

So before I saw these last 2 replies, I went ahead and bit the dumb bullet and created an account on freenass with the same name as my win10 user and.... it worked. By the sounds of these last 2 replies, that is NOT necessary, so now I am more confused as to why that worked.

I've got an old HP ProLiant N54L (which is awesome), but is sadly really bottlenecked by only having four (five) internal bays. I'd like to expand that using some external storage - I'm thinking the easiest way would be to get a USB 3 HD enclosure and a compatible HBA? I'm assuming USB 3 will have no trouble serving up a bunch of 5400RPM WD Reds. Just want to make sure I'm not planning anything fundamentally retarded here.

If you're buying an enclosure anyway then can't you hook something up to the eSATA port that's already in the Microserver?
