So did a test this morning and set all of my drives to Level 64 Power Management as well as "Medium Acoustic Output." Turns out that was a mistake. I could hear them keep powering/spinning down and was annoyed by that, so I went to change back to the previous settings. But it seems like it hasn't changed anything, they still spin down (I can hear them "wake up" as soon as I call the file system). Not sure if it's all of them or just one, but this is annoying as well.

Isn't that guideline for busy multiuser environments though? What is ZFS going to use it for other than ARC, if you don't do dedupe? A single-user system at home streaming media and hosting backups should be able to get away with much less.

Would this used server be a nice buy at that price? It basically seems complete aside from adding hard-drives to it, and it has way more than enough power to do what I was originally planning to with my from-scratch build, as well as having enough bays to last for a long, long time, and is cheaper than the combined parts I was going to make mine from. I can't cannibalize the parts in it, so I'd have to deal with a huge 2U rack-server, but otherwise, would it be okay for something like unRaid? I could ignore the raid controller or take it out, yeah?

Hi Jinx posted:ZFS won't make things worse than they would be with a cheap non-ECC NAS or a consumer motherboard RAID. Maybe I'm wrong, because the regular scrub runs could actually gently caress up your data due to random bit errors when otherwise it'd be safe on disk? You're probably still better off with ZFS. D.

Combat Pretzel posted:That's a guideline for enterprise scenarios, where large amounts of data are in-flight and/or need to be accessible as fast as possible. This doesn't apply to SOHO scenarios. And it also doesn't mean the OS would be starved out of memory, if you don't follow the guideline. It just means that there isn't as much data (and metadata) cached. Also, the ARC isn't fix in size, if you raise the memory pressure via apps, it'll back off.

It's a 2U server with two power hungry processors inside, it's going to need to run those small fans at a very high RPM. That is going to be very, very loud. You wouldn't have to get rid of the RAID card. Just run it in JBOD mode so it passes the disks through to whatever OS you decide on. (If you are not running ZFS in the OS though, I'd just stick with hardware RAID.) If you're looking at Supermicro and noise is an issue, I would suggest you go to a 4U setup based on the 846 or 847 series chassis. They're still very loud, but it's not impossible to mod them to be friendlier. You also get a lot more disks. :p

I run something like 40TB of pools with only 12 GB of ram and I can saturate my gigabit network and the server gets used for lots of other stuff as well. Ram isn't near as important for home usage as some people say.

Getting in late on ESD chat: The fun thing about ESD damage is that it causes two categories of failure, catastrophic and latent. People intuitively think that because they don't see immediate (catastrophic) failures when they don't bother with ESD safety, well that must mean it's all pointless. But... You know how when you build up a static charge and touch something grounded you can get a visible spark, and it hurts? That much energy is way more than enough to vaporize a metal layer connection in a chip, because those "wires" are so very thin. Discharges you can't even feel are enough to do this. Such events don't always break the connection permanently: some of the metal re-solidifies into a new wire good enough for the circuit to work okay, but these often become very slow blowing fuses rather than normal connections. This is one of the many fun ways ESD causes latent failures. It can take years for some of these to progress into an unambiguous "poo poo's broken" failure. Sometimes the IC is only mostly fine before it breaks completely, ie there are little glitches now and then. One reason lots of people get away without taking ESD seriously when assembling PCs from whitebox parts is that it's a much bigger deal before components have been assembled onto a circuit board. Once they are, there's many more paths for charge to dissipate harmlessly in things which can take it, any given injection of charge has a decent chance of splitting between multiple components (decreasing the risk to each), and so on. It doesn't become impossible to harm things, but it is much less likely. I've been a guest inside a professional PCB assembly and rework factory. You were not allowed to set foot on the factory ESD-safe floor without a shoe grounding strap (or ESD shoes, which basically have a grounding strap built in) and an ESD-safe labcoat, and would get in real trouble for not using a wrist grounding strap while handling stuff at a bench. You don't have to go this crazy when building a PC, but basic measures will get you a long way.

I've personally broken two motherboards from ESD damage in a row after constantly rubbing them against the case during winter. Also, I've gotten plenty of sticks of dead RAM during winter months. The worst part was that touching grounded metal frequently didn't help when you have so little humidity and you're on carpet on top of a really static-y chair mat. I didn't care too much at the time because I'd never had anything happen after 15 years of working on computers but I don't mess around anymore after losing $700 of equipment within 2 months like that.

A local computer store is having a clearout on HP ML150 G9s (1xE5-2603v3, 8GB, B140i) for ~$900CAD and I'm tempted. I use HP stuff at work a fair bit so I know the quirks and how updates end without a support contract but it could be a pretty sweet server/NAS box.. Good idea? Bad idea?

Seems an awful lot just for 8 HD slots... does it come with any HDs, or just the cages? You can get an ECC motherboard/cpu/ram/case for much less than $900 if you just want the ECC memory.

I'm not sure I'm in the right thread; feel free to send me elsewhere. I need a network storage box to run Plex, a torrent client, and host a lot of music and video files. It's replacing an ancient PC whose Ethernet and USB sockets are dying, and in any case does not support USB-3. The obvious choice would be to buy a consumer box, but Plex can't transcode on the fly on any of the consumer NAS devices I can find. I also need a box that can run a browser so I can use it to print files on Unix Cloud Print. I can use Emacs and the Unix command line and can install packages on Ubuntu. I'm not a sophisticated sysadmin, nor ever have been. A consumer NAS won't work; a Windows box won't work, because I'd rather sysadmin Ubuntu than Windows. Which thread should I go to for a cheap build-your-own Unix-based media server? (e: Also feel free to tell me why I should use Windows.) edit edit: All my music files are in FLAC, so an MP3-only streamer won't work.

Ubuntu's fine for a first server. My Ubuntu server's been happily running 14.04 since that LTS came out, and managed to put up with an amateur Linux user messing around with various packages. It's due a good OS overhaul/upgrade when I get time.

I use them both, Plex for transcoding to my Phone and Tablet, Kodi on the TV. They both look at the same NAS folder for media, works out pretty well.

Mr Shiny Pants posted:I use them both, Plex for transcoding to my Phone and Tablet, Kodi on the TV. FWIW, you might want to use emby instead of plex. It seamlessly takes over managing your Kodi library while at the same time giving you device streaming capabilities. The point is that your watched status and metadata stays in sync between emby clients and Kodi. A Plex addon for Kodi that does the same recently came out but I don't know much about it because I prefer emby.

Thanks Ants posted:You can also point Kodi at an external database if you just wanted to sync the metadata:  I use the external database thing, just so if the MicroSD card in my rPi ever waves the white flag, I can be back up and running in no time. Although, I had no idea about the emby thing. I use Plex strictly only on my fireTV Stick. Is there a way to sync that data with the SQL database? I guess I could always try sideloading Kodi on the fireTV Stick, but im not sure I'd be able to change the config to point to the DB. This is probably the wrong thread for this, but I hadn't thought about it til you guys brought it up

Way off topic, but I fly internationally a lot and my iPad is about 80 gigs of synced tv shows I have no other time to watch. Does anyone have a mobile app anywhere near the class of plex pass for iOS for that use case? I just say keep the last 5 episodes unwatched of these 20 shows and every time I'm near wifi it gets freshened. F

(emby does this too) I swear I like Plex as well, I just moved to Emby for mobile streaming when they came out with the Kodi integration. Probably should finish up this thread derail by taking it to the Emby thread.

I use this app to do a scheduled file transfer from phone to a samba share on my home server: https://plus.google.com/communities/101884705965609685163 I've set it to sync every second hour, doing a simple directory sync. If I'm not at home and the sync obviously fails it's discretely recorded in the sync logs without annoying me.

Yeah, it probably does work fine there - especially for non-battery powered devices. And it may have come on since last year when I tried it. I'm pretty sure I'd just use a network / sshfs share or rsync to avoid the need in that case though.

Hi all-knowledgeable NAS goons! I've asked a few questions in this thread before and got some great advice (which I ultimately have never used due to various reasons). But I have a new set of questions so I can confirm what I'm thinking. I'm about to go balls to the wall with my mini-ITX build and remove my 3.5" bay; so that won't be an option to consider. Basically, I want to store GoPro videos of me and my dad motorbike riding, store music and videos on something that I can easily access (as I'm planning on getting a 1TB SSD to accompany my current, 250GB SSD in my build, it soon won't be feasible to store all this stuff in my actual computer). So all of the stuff I want to do is pretty simple and I know almost any NAS will be able to do it, but here's my questions: 1) My home internet is absolutely woeful (it took 3 days to upload a 15 minute video to YouTube), am I correct in assuming that once this stuff is downloaded, the transfer to the NAS is actually limited by the slowest local piece of equipment (likely my modem/router)? I.e. The transfer of data will be a lot quicker? 2) Assuming the above is correct, do I actually have to have my NAS connected via Ethernet to my modem, or can it all be done via wifi? 3) Do I still need to actually back this data up, or will having the NAS in (insert whatever array# appropriate) be sufficient? 4) Assuming I'm correct on points 1 and 2, what's a good 2 bay NAS? Thanks in advance goons
