Selachian posted:As for Amazon, while cloud backups are great for supplemental security, as an archivist I am biased toward having a local copy that I can see, handle, and control myself, as opposed to having the materials off on someone else's computers who knows where, and at the mercy of someone else's policies. Yeah, it may seem overly paranoid to worry about Amazon going out of business, but a century ago people would've said the same about Woolworth's. Better options for putting the data somewhere on a bad budget honestly IMO is to use large hard drives locally, burn DVD+R gold media, and use Backblaze B2 Cloud or Wasabi cloud and make sure to keep tabs on them to make sure they're not going out of business (these providers do not charge for data egress and monthly costs are far, far lower with good enough reliability). Also, you will need a workflow well documented and easy enough to maintain across future OSes. In the scheme of hundreds of years, Amazon isn't terribly different than these smaller companies and you'll need to give enough help so someone can re-do all the crap all over again in maybe 30 years (holographic storage? water droplets? bacteria? COVID-49? who knows?). The big problem for most education-adjacent institutions right now really is budget - it is jaw-droppingly bad in every continent and name-drop I've ever seen (I'm aware of what even Ivy League museums fund - it's labors of love all around). Business needs are not the same thing as archival needs in any way due to the fact that no nation state is trying to take down your archive.... at this time, and they have much more regulatory scrutiny overall.

I have 3 WD reds in raidz in my home NAS, all purchased at the same time, and it just occurred to me that they've been running continuously for 6 years. FreeNAS is still perfectly happy with all 3 of them, but they're getting up there. Should I think about throwing in a spare or two before something terrible happens?

I think it depends on a lot of factors (usage patterns, temperature, etc) but the general rule of thumb I have been using is replacing the drives in my NAS every 4 years (assuming 24/7 operation). Some more info on this from Backblaze: https://www.backblaze.com/blog/how-long-do-disk-drives-last/ Is the data on your drives irreplaceable? Do you have backups? Have you verified your ability to restore from a backup if necessary?

Resilvering always looks... interesting when you've got 'top -aHIjStqz -s 1' running: All of the threads end up being about 110% CPU, but distributed over 8 CPU cores with SMT, so it's barely warming the server up compared to a full package build. The upshot is that I went from 4.71TiB to 9.51TiB of usable storage by replacing two 5400RPM 466GiB drives, and there's still another 7200RPM 932GiB drive to be replaced before the pool will reach its penultimate size. I hope I can live with 21TiB usable storage for archival purposes for a while, because it'll take me some time to replace 15 disks with ~8TB disks at which point it'll reach its final size - unless I'm forced to go for even bigger drives to avoid SMR.

I just had a Synology 415+ stop booting up on me. All 4 hard drive lights are amber and the blue power LED flashes for a few minutes, then the device powers off. I received it from a family member who salvaged it from work after it received very little use, so I have no possible way to put in a warranty claim (plus it's probably too old). I'm seeing that soldering a 100 ohm capacitor to a specific spot on the motherboard fixed the problem for multiple people on Synology's forums. That said, I don't have a soldering kit and I don't really want to do that unless I have no other recourse. Has anyone had this problem and was able to fix it?

Has anyone had this problem and was able to fix it? if it's what I'm thinking about, this is a known problem with a whole series of Intel processors, they lose the ability to generate the clock signal needed to drive the initial stages of the bootup, and there's not really much you can do. But it doesn't hurt to send Synology an email and see what they say, just don't mention that you don't have a receipt https://www.anandtech.com/show/11110/semi-critical-intel-atom-c2000-flaw-discovered

You definitely need to solder it on - it's an external fix for a hardware fault in the CPU die. Without it, the CPU won't receive a valid clock. Do you have a friend, or local makerspace? The hard part is disassembling the case, actually soldering on a 1 cent resistor if you have a soldering iron takes only 10 seconds or so.

Err yeah, resistor. I do have people I can borrow a soldering iron from but my entire area is under public health orders so it's a bit more difficult to get my hands on something like that. My work may have one (or someone at work may have a personal one) that I can borrow. I'll look into how to disassemble the case, I guess. Edit: I also haven't soldered anything in about 20 years so I'm a bit hesitant to do it myself, but I'm sure it's not terribly difficult.

Seconding the recommendation to send Synology an email about it. They might be more inclined to help since it was a widely known hardware fault. If you're worried, you could probably find a techie friend to do it for you. It's pretty simple. Also, look at it this way: it already doesn't work, so what do you have to lose?

Thankfully the pins you need to solder to are routed to an unpopulated header, so you can use a ye olde throughhole resistor part and pretty much any iron known to man. Not surface mount parts or fancy equipment required, so very little skills needed. Here's a repair video (Dave from EEVBlog's sketchy version of the fix shown around the 8:!2 mark): https://www.youtube.com/watch?v=Y8_emfoR_MI&t=492s

The resistor fix for the DS415+ seen on that is a valid fix. It will work unless the psu also went out. No problem asking if still out of warranty as it was given an extra year of warranty.

Looks like a Backblaze module. It's going to be deafening. Anything designed to be in a datacenter is not designed to be quiet. It won't be as loud as something which has to use 1U fans, but noise reduction is not on the design criteria. Like, even if you put this thing in a closet you're going to hear a loud din through the door. You are really going to want to put it in a garage or somewhere several layers removed from places where you want quiet.

Ever since I set up Unraid a couple months ago I was stuck between having NVENC or DVB support, so I went with NVENC and used a Pi for TVHeadend. Eventually I wanted to switch to Plex's PVR backend and while I could have piped it in from TVH I really hate dealing with TVH (only a little bit more than I hate dealing with Plex) Unraid Kernel Helper/Builder finally let me build Unraid with both, with a bonus of making it fairly easy to copy in a specific, older version of the USB TV tuner firmware that works more reliably with my hardware. Everything is working pretty smoothly now, with the addition that NVENC session unlock script I think I got everything I want.

I vehemently agree with separating that box away from your living space as much as possible, but a 4U like that should be able to be made quiet enough to at least be livable in a closet. Those are all standard-size fans where you can easily find quieter versions (or just put them on a fan controller). The CPU has a regular heatsink/fan so it's not going to be dependent on high velocity air moving from the front of the case to the rear, and it's not a particularly hot chip either.

In my experience the loudest part is going to be the redundant PSU fans, they're very small and very high RPM.

Hell even the expensive ones that have actual baffles and air tight seals only reduce noise by up to 30ish db.

Yeah, 30dba is significant but not enough to be "quiet" merely "not so loud as to hurt your ears." It's also white noise, so everything you want to listen to you will have to turn WAY up to understand over it. Dell says a datacenter is "75dba" so if it cuts it to 45dba it's as loud as my dishwasher - which is pretty quiet but not inaudible. If you can use all large high quality fans it might get it down to tolerable but still not something I would want to deal with, and lol adding thousands to buy a rack.
