What is your budget? Max $1000 (not including parity & data drives), though I'd prefer a lot less if possible. How many drives do you want your server to be able to support and how much capacity do you need? 1 parity, 1 cache, and 4 data drives (unRAID basic) Are you interested in running additional apps? This will be for media storage and possibly a torrent seedbox. Do you want to run green/low power drives or faster 7200 rpm drives? I will be using 4x 20TB IronWolf Pros and I don't want them to be limited in anyway during parity syncs. Do you have any spare parts laying around that you would like to apply towards your build? Building from scratch. Other requirements: Intel 2.5G NIC 1TB NVMe cache Fully modular PSU (gold or better) Case with good out of box cooling for HDDs --------------------------- Not really sure where to start. Was looking up suggested builds around this price range but didn't find much. Don't want to blind buy some parts and have potential issues. Any help would be appreciated.

My requirements: 2.5G or 10G NVMe Cache 6 Drives (not including NVMe cache) I'll be using 6x 18TB IronWolf Pro drives. Doesn't need to be super fast, mainly a storage server with next to no docker usage, so cheap as possible without being slow.

Even a game play Stardew Valley at 720p gets 20-25fps and constantly drops to single digits. I have 10GB of ram allocated to the VM and a i5-9400. My 7 year old entry level laptop with an AMD processor and no GPU gets 60FPS in this game. I have selected Intel 630 graphics in the VM and it detects it, even installed the intel graphic drivers. I am connecting via Remote Desktop Connection but overall most animations feel slow even on desktop. Any ideas?

Two drives have been getting CRC errors. I have a Norco 4224 which is basically famous for having faulty hotswap bays. I have tried the following in this order: - Swapping SAS cables around. Same drives kept erroring. - Different ports on my SAS cards. Same drives kept erroring. - Replacing the hotswap bays backplates (I had 3 spares, tried all 3). Same drives kept erroring. - Rotating drives around. New drives started erroring, same hotswap bays. This told me that it HAD to be something related to those hotswap bays, but I already replaced them soo... - Rotated PSU cables. Different drives started erroring but still 2 drives. Oh so it's a bad PSU cable? - Replaced the "bad" PSU cable with one I know is good. Same drives kept erroring. - Swapped the PSU cable on the PSU end to another port. Same drives kept erroring. My mind is blown. I have covered every single thing and nothing makes sense unless there is multiple issues causing CRC errors. At this point I was meaning to do a server upgrade so.. - Swapped out entire mobo/ram/cpu for new ones. Same issue. Only thing I can think of is replacing the entire PSU and all it's cables. Not sure what else it could be at this point.

Dual parity with 28 data drives. Last two monthly parity checks averaged 140MB/s and started at 190MB/s. I recently upgraded mobo/ram/cpu, but even before that I checked parity and it was going only 110-115MB/s and stayed there the entire time. The same is happening on the new mobo/ram/cpu too. This will take an estimated 2 days for parity checks. I have tried tweaking nr_requests and md_num_stripes and it seemingly has no effect. Specs: i5 9400 ASRock B365M Pro4 2x LSI 16i SAS Cards (All 30 drives drives connected to these) 8TB drives with a few 12TB Segates Any ideas?

Thank you

Can someone help me with custom cron entry schedule? The first sunday of every month at 3AM, once a month. Is this right cause I think this will just run it every Sunday which is too much... 0 3 * 1-12 0 Thanks.

Thanks for the information, that's almost surely what's going on. I haven't done a parity check since 6.8 released. Will wait for fix.

I replaced my 3x SAS2LP (because they aren't recommended anymore) with 2x LSI 16i cards. The server consists of 28x 8+ TB drives and 2x Parity drives, the maximum unRAID allows. Prior to the swap, the SAS2LP cards were getting about 180-200MB at the start of parity. I am now getting 130-140MB/s. Estimated completion is 1 day 6 hours. I have tried tweaking nr_requests and md_num_stripes. md_num_stripes has an affect, but only up to about 4096. Any lower and it goes much slower. The cards are installed in PCI3.0 x16 slots (cards are x8). Should be plenty of bandwidth. Cards were flashed to latest v20 firmware. Any ideas?

Oh that works, thanks didn't know about that plugin.

With 12TB drives parity takes about a day and media stutters during this, especially remuxed BD and 4K content, which leaves the server pretty crippled for one day out of the month. As a result, I swapped to bi-monthly parity checks which isn't ideal. The server is vastly overkill with an i7 9700k, 32GB DDR4, etc. The problem is the drives get fully loaded. I remember "low priority" parity checks were a feature planned to be implemented but it's been a few years and I haven't seen anything. Any solutions to this problem?

I went from running 3x SAS2LP to 2x SAS2LP and 1x LSI card so I could expand to 30 drives and dual parity. However, NR_REQUESTS set to 8 slows down the LSI card and it's well known the SAS2LP cards need this tweak for ideal parity speeds. I am getting almost 2 day parity checks with 12TB drives (130MB/s) now. I have tried various middle grounds like 16,32,64 but nothing gets the speeds up to where they should be. I was getting 190-200MB/s before. There seems to be no way to fix this other than buy a second LSI card and get rid of the 2x SAS2LP cards? Anyway I can fix this without spending another $200?

Ah damn. So is the Norco. Sooo what's the cheapest 32+ bay case for 3.5" drives? I can't find any that are under $2000 because they come with hardware. I have 2x Norco 4224 cases. Couldn't I just buy the SAS cards, stack the cases on top of each other, drill some holes, and just use bays in the other case? Not ideal, but it beats spending $2000.

Whats your thoughts on this 36 bay case? Only 2 120mm fans. Seems toasty. I can't find any images of the insides. I believe they are SAS connectors inside? I am not dealing with 36x SATA (lol) https://www.newegg.com/istarusa-d-410-de36/p/N82E16811165665?Description=36-Bay Hotswap&cm_re=36-Bay_Hotswap-_-11-165-665-_-Product&quicklink=true

Any other 32bay cases you know of? Ideally I'd want something like 6U but they all come with existing hardware ($2000+). The norco is the cheapest 32bay I can find by far.
