Where do people stand on plugging/unplugging the SATA power on a drive while it's running to simulate a failure on a ZFS array? Should I just not be lazy and shut down before I unplug?

Well, I could export the zpool first, but I've decided I'm not gonna be a lazy bastard and shut it down instead. I've been printing out labels for all my drives with model and serial number on them. I just need to disconnect one of the mirror pair to determine which serial is which. It'll take 20 minutes to do everything properly and then when a drive does fail I'll know exactly which one to pull because they'll all have serials stuck to them.

Chances are pretty low youd have an issue between drive getting it into cache and writing to flash, so youre most likely fairly safe and the error correction from zfs probably renders it moot anyway!

I've already shut my VM's down, shut the rig down and pulled power to one of the mirror drives. It's rebooting now. I'll SSH in, do a lsblk/smartctl to see which serial has went offline and then shutdown and plug it all back in again. Then they'll be stickered for if one actually dies some time.

Do it twice.

Yeah definitely do it for a test just thats what could happen. In system stress testing is a good thing!

Chassis' designed for hotswap have backplanes with capasitors to handle the power surges involved with disconnecting and connecting drives, but if you're only doing it a few times I honestly don't see it mattering unless the manefacturer built to the absolutely lowest spec possible or you have hardware that's on the verge of failing already. The upside of knowing whether your automation works, whether its hotspares or automatic replacement with something like zfsd, is definitely worth it.

Haha. I like it that you can be buzzed on brunch. The job's don'e now. I plan on moving everything over to SSD's when prices tumble even further. I don't use a huge amount of storage as I regularly delete stuff from my movie library after I watch it. A bunch of SSD's in a PC case will be so much easier to physically manage, too. I guess once I've replaced spinners with SSD's I may pull the power if I want a simulation. At the moment I'll just leave my WD reds spinning another 6 months.

Did someone mention 3tb drives being generally unreliable ? Here's the worst once I've got in my 16 drive NAS - over 5 years of 24/7, max temp 63c, no errors. Toshiba DT01ACA300. ![]()

Beaucoup Haram posted:Did someone mention 3tb drives being generally unreliable ? I have nothing but my own anecdotal data on this but as someone (me) who owned about 70 hard drives in their lives, the only ones I ever had die were ones that were "odd" numbers, as in they got to that number of GB or TB in some non-standard means. My hard drives that have died: 400GB WD drives (I had three of those fuckers die on me), a 1.5TB drive, a 3TB drive, and a 6 TB drive. I've never had a 1TB, 2TB, 500GB, 4TB, or 8TB drive die on me (except for the 8TB I dropped on the floor thanks to me pain in the ass cat).

I need to figure out which is going to be the better option. I need it to run some basic usenet apps and Plex. If I go with the 1st option, I'll just keep running Plex off my PC with the files on the NAS. Do I stick with my DS213J and swap the drives out for 2x8TB? Do I use my current leftover parts from a PC upgrade, buy the missing ones + drives and run ZFS or something? Buy a newer NAS that can do Plex and add drives to that instead?

I'm using an old i7 desktop (930, 1366 socket) for my Plex server (amongst other things) and since the CPU is really old I want to offload a lot of the transcoding in Plex to the GPU. I have an Nvidia GTX 650 and was wondering if that's enough or if I need to buy something newer? I know it's old as hell but I don't want to spend money if I don't have to. If it's too old to be useful for Plex, is there a cheapish NVidia GPU that is recommended that will only take up 1 bracket in a tower?

I thought a GT 1030 was the correct answer and was typing up a post on that, but then went to reconfirm, and Nvidia has told me that I'm a damn fool. Based on that, it looks like a 1050 is the lowest end one that does both decoding and encoding of x264 and x265.

The best, lowest power option is a Quadro P2000.

Wouldn't a modern Intel CPU have decode and quicksync encode? I dunno of Plex can take advantage of Quicksync though.

I saw it drop to $350 new recently at Dell. In some setups it beats using more expensive general purpose CPU, especially for real-time HEVC encodes which can let you reduce egress bandwidth consumption. But if youre looking at that card as a media PC type user youve spent probably well over $2k in hardware to push out a lot of media. QuickSync only has so many concurrent encodes possible and while the P2000 is 2x decoder and single encoder limited its API unlimited and can be useful in that respect at least compared to most GeForce cards that are single user only.

Plex can do Quicksync. But an i7-930 is pre-Sandy Bridge, so it doesn't support Quicksync. The reason it was relevant to me was that a buddy of mine has a Haswell, but wanted to do HEVC, which wasn't supported until Skylake. It's significantly cheaper to grab a 1050 than to replace board, processor, and RAM, which is why I suggested it.

I only found ONE on all of eBay that is single-slot, and of course it's some weird-looking one that has zero branding on it whatsoever: https://www.ebay.com/itm/NVIDIA-Geo...09/232943590864 I mean I've never seen a video card with no brand and no mention anywhere on the card of what the model number is. Does Aliexpress make fake video cards now or something or should I be OK ordering this one? My dumb ass motherboard has a PCI-E mini slot right under the graphics card slot so I'm limited to exactly this card I linked if I want a 1050

https://developer.nvidia.com/video-...-support-matrix P2000 is one of the cheapest unrestricted sessions GPU. Its really nice if you want to quite a few transcodes at once.

WWWWWWWWWWWWWWWWWW posted:motherboard has a PCI-E mini slot right under the graphics card slot I have the same issue, if I put a dual slot graphics card in the TS430 (which also has to be bus powered so a GTX 1050 Ti looks likely), then I'll loose a PCI-e 1x slot beneath the 16x slot. I can see a bunch of extender cables on Amazon should I ever wish to use that slot, thanks to our new post bitcoin mining wasteland... but is that a workable idea? I think I may end up just loosing the slot but we'l see.

It seems to be an OEM card, which makes the lack of branding make a lot more sense - I had a similarly featureless OEM GT640. It looks like the cooler is higher than single-slot and lines up with the data pins in the PCIe connector, so this still probably won't fit with an x1 in the next slot unless you replace the cooler.

I'm surprised the 750ti isn't good enough for Plex decoding to be honest, especially since it had some sort of dedicated chip for video compression (possibly related to remote-play only; I'm not sure).

This is also making me wonder if I should not just make this a gaming PC at this point. It's a Windows 10 machine, with 20 hard drives (13 internal, 7 external), an admittedly old 930 i7 but it's overclocked to 4.1ghz and is about to get a decent video card and 16gb of RAM. Now if all this thing is doing all day is using Sonarr, qbittorrent, and most importantly Plex, is there any reason I can't also use it for games at the same time? The days of me being able to sit in front of a gaming PC are over, but I have NVidia Shield TVs all over the house and Limelight worked great when I tried it years ago. Or is this going to be too much stuff for the PC to do at once? I am not expecting to play AAA 2019 releases with graphics set to high, but streaming Dead Rising 2 to my living room would be pretty awesome. edit: I forgot to mention I also have a Plex Pass and its set to record live TV and I am guessing that is pretty intensive?

I think I may end up just loosing the slot but we'l see. Can you link me to the extender you've found? I just keep finding some other weird PSU extenders. I have a USB 3.0 PCIe card and want to still be able to use it with the GTX 1050 installed. Luckily my Fractal Design case has two rear vertical PCI slots so this extender would work for me. If you have a case like this, it would work well for you too. If not, I really recommend this case. Not only does it internally hold 13 hard drives (2 of them being 2.5", the rest 3.5") but the hard drive area has its own two huge fans and you can access every part of the motherboard without having to remove anything, on top of all of the wires being hidden no matter how messy you want to be (the PSU is on the bottom and everything goes through holes to the motherboard so you are actually forced to make everything super neat and tidy; it's great). Anyway I would greatly appreciate a link to the extender you found. edit: also what exactly is this? https://www.ebay.com/itm/GTX1050Ti-...VI/382822201927 Is that a fake video card or something?
