unraidun

Every time I select memtest from the boot options, I get one line of text (too fast to read it) then my machine reboots. Google came up with this... https://www.passmark.com/forum/memtest86/40884-memtest-reboots-before-test-begins ...think this is a 'multi processor' issue? My system... Asus TUF Gaming X570-Plus AMD Ryzen 5 1600 16g Corsair Vengence DDR4 RAM Anyone encountered this before?

Yup, able to http in just fine. So the 'Allow UEFI Boot' tick box definitely did the trick (it's a shame it's hidden under the 'customize' section of the wizard). Now I need to figure out why I just get a flashing _ when I boot into GUI mode... *well guess I will mark this topic as solved. Don't really care about GUI mode as long as I can remote in...

OK making some progress. Re ran the flash maker and noticed if you click 'customize' there is an 'Allow UEFI Boot' tick box, so I checked that. Now I can get to the boot screen, but when I select GUI mode, it looks like it's starting, but then just a black screen with a flashing _ . Going to try no GUI mode now to see if I can at least http to it...

Asus TUF Gaming X570-Plus AMD Ryzen 5 1600 16g Corsair Vengence DDR4 RAM Have my usb flash drive as the primary boot device (only device listed). Tried disabling legacy usb support. Tried enabling CSM and setting all options to UEFI (read that worked in another thread). Tried different usb ports (this MB only has 3.0 ports so can't try a 2.0 port). Yet every time I power on my box, it goes straight into bios (after the TUF Gaming logo). Tried running the flash creator "Unraid.USB.Creator.Win32-1.6" (is there no 64 bit version?) on two brand new "SanDisk Cruzer Fit 16 GB". The first time I formatted before running, the second time I just ran the exe. Both times I got 'write successful', at which point I assumed I was done, so I closed the window (I don't need to run 'make bootable' if I use the wizard/app right?). Any ideas?

Does anyone have experience with the new xfs scrub command? Or some other way to preemptively check the health of a file/disk? That seems to be one of the biggest differences between the two file systems. Or perhaps there is some other xfs or btrfs feature I am overlooking? But as I do more research on btrfs, it does seem like most of the bells and whistles it provides are useless for a simple 'write once read many media archive file server'...

So I've spent a lot of time researching the differences between XFS/BTRFS. All of the 'issues'/instability with BTRFS seem to be from years ago, mostly relating to RAID (which isn't a factor for us, right?). There have been a handful of threads here on the forums, but I would expect more discussion when it comes to such an important (irreversible) decision.. The big selling point for me is data validation. Being able to periodically run 'btrfs scrub' just to verify the health of the disks (and system/memory overall) is a huge selling point. The peace of mind you get from that can't be under valued. I was hoping XFS had something similar, and there does seem to be a new 'xfs scrub' command, but does that actually work like BTRFS? Are there even checksums to verify? Or is there some BETTER way to detect if a drive is silently failing/corrupting data with XFS? Bottom line, if you're going to use UnRaid for a large file/media server (seems to be the most common use case), the only two major concerns I have are... 1.) How much wasted space does BTRFS generate (meta data etc...), and 2.) How much slower is BTRFS when reading/writing files. In the context of a file/media server, I have a feeling the answer to both of those questions is : an insignificant amount. Assuming that is all true, can anyone convince me to use XFS instead? Thanks *and just out of curiosity, what is the logic behind forcing us to use BTRFS for the cache drive?

Hrmm ok so I guess that's one major Pro for BTRFS. But file validation aside, are there any other major differences one should consider when deciding on XFS vs BTRFS (for a typical file/media server)? Honestly I'm still leaning towards XFS (I agree with you guys, the chances of the hardware not catching write errors is slim), but I just want to make sure there isn't something else I'm missing...

Anyone else with XFS experience able to comment on this? XFS must have some way to validate files (something like a btrfs scrub command) right?

Hmm that's unfortunate. But in theory, if you have enough information to rebuild an entire disk, don't you also have enough information to rebuild a single file (assuming you know exactly where the bits exist)? So in the meantime, there is NO way to validate a file after doing a copy in XFS? Again, willing to initiate some kind of manual scrub command (doesn't have to be automatic/native to the file system).

For our work archive/media store, we plan on sending files (massive projects, pictures & video, all of which we need to stream over 10g lan) first to a dedicated ‘uploads’ share. Once a file is placed in uploads, the root admin will manually move them (via Krusader) to the main 'Archives' unraid array (perhaps we could use a script to automate this copy, if no files are being renamed/deleted). In theory, once a file is written, it will rarely (if ever) be touched again. The idea being, we can expose 'Archives' to all users (since it’s read only), and not have to worry about accidental deletion, ransomware, etc… So given this specific use case, XFS or BTRFS for the main array? A feature we would like to have is some way to checksum/validate a file (not every read, just on initial write and then manually/periodically), and recover corrupted files from parity (hopefully without rebuilding the entire disk?). Essentially what we’re trying to figure out is, are there any relevant differences (for this case) between the two file systems? I imagine it is not trivial to switch after picking one, so just trying to avoid buyers remorse before committing (currently leaning towards XFS…). Thanks

In my never ending quest for peace of mind, I came across these 'power supply testers'... https://www.amazon.com/Computer-PC-Tester-Connectors-Enclosure/dp/B076CLNPPK/ref=sr_1_3?keywords=power+supply+tester&qid=1579037405&sr=8-3 For only 13 bucks, seems like a good investment? Especially since the ps I plan to use is a reclaimed part from an old gaming rig (3 year old Corsair CX 750m). Blew out the dust this morning, hasn't been powered on in ages... Would a little device like that tell me if my PS is 'good'? And I suppose I could also use it to test these molex->sata cables too eh?

I think you're right. So I guess the game plan is just to use the 'best' recommended name brand (Monoprice) molex->sata adapter (the reviews confirm it is crimped, so should be less likely to fail). https://www.amazon.com/Monoprice-108794-24-Inch-15-Pin-Female/dp/B009GULFJ0 And just do one adapter (4 drives) per molex. On the plus side, using a molex->sata adapter means I won't have to do the 3rd pin mod for all these shucked WD drives

While doing research on how to power all my sata drives, I came across lots of scary stories about molex->sata power adapters catching fire. This guy on youtube made an interesting video about what to avoid when selecting such an adapter... https://www.youtube.com/watch?v=TataDaUNEFc&feature=youtu.be&t=117 *sadly enough, the same guy had one catch fire because he ignored his own advice... https://www.youtube.com/watch?v=EYkof-csPfI *and the cable autopsy -> https://www.youtube.com/watch?v=fAyy_WOSdVc Well that's just great. Now I'm super paranoid. I HAD planned on using a "good" molex->sata power adapter (one recommended by jonathanm and many others), but I'm still nervous... https://www.amazon.com/gp/product/B009GULFJ0/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1 Looking for alternatives to molex, I found a company that sells extra 6pin->sata power cables for my Corsair CX 750m ps, so I thought, great, now I don't have to use those molex adapters. But then I thought, wait, is the problem with the molex, or the sata end of the cable? According to the videos I've seen, it sounds like the sata end is the culprit here. If it isn't shielded properly, the arc which causes the fire will happen regardless (molex or not), right? Does that mean the molex->sata adapter I linked IS indeed "safe" because it appears to be properly shielded/terminated? It just seems like even if I use pure sata power cables, I will still need to use a at least one male->female sata power extension cable (the default cable from my ps isn't long enough). And while that may be safer than a janky molex adapter, isn't a one to one sata power extender still a potential fire hazard? Thanks for any insight!

Was about to order two of those COMeap 6pin -> Molex ps cords, and I saw they DO make sata versions (which also claim to be compatible with my Corsair ps)... https://www.amazon.com/COMeap-Adapter-Corsair-Modular-Supply/dp/B0823989PS/ref=sr_1_6_sspa?keywords=comeap+corsair+6+pin+sata&qid=1578972588&s=electronics&sr=1-6-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUFXSEMxWFROWERHJmVuY3J5cHRlZElkPUEwNTAxMzM5VDFUUVAzUUxFNDk0JmVuY3J5cHRlZEFkSWQ9QTAzNDI1NDFPRTZQMUZUTTRNMUwmd2lkZ2V0TmFtZT1zcF9idGYmYWN0aW9uPWNsaWNrUmVkaXJlY3QmZG9Ob3RMb2dDbGljaz10cnVl So I COULD in theory power everything with pure sata (no molex -> sata adapters), but then my cables won't be long enough to reach the farthest drive bay. My case seems like it's pretty common server dimensions (Rosewill L4500 server chasis). How in the heck do you guys power your far corner drives WITHOUT resorting to daisy chaining/adapters? Would tacking on a simple male->female 3 inch sata extension cable to each port be better/safer than the previous plan (molex->sata)? *sorry didn't mean to hijack this thread, started a new thread regarding this issue/sata port fires...

Cool thanks again! Just ordered two of those adapters (I will play it safe, and start with just 4 drives on each line, 8 total). Maybe by the time I get a 9th drive I will have purchased another modular ps I can steal a molex from... ** Oh wait! All this time I had been searching for a SATA extra/replacement cable for my modular ps, I just searched for Molex and this came up... https://www.amazon.com/COMeap-Corsair-Modular-Supply-Adapter/dp/B07GRM7MRD/ref=sr_1_1?keywords=molex+modular+power+supply&qid=1578889107&s=electronics&sr=1-1 The pictures look kinda scary ("if you use other brand psu's it will burn..."), but they explicitly mentioned my corsair cx as being supported... So just get one of these + one of those 4 way sata adapters (for every 4 drives), and I am golden, right?

Unfortunately I only have 2 molex cables for my modular ps (Corsair 750 CX M). I couldn't find anyplace that sells extras/replacements, or I would happily run 3 lines instead of just two. But do you think my Corsair has "good enough regulation"? *btw, how can you tell those sata adapters are the good 'won't catch on fire' kind? Is there something special about the shielding or how they are threaded through the connectors?

Cool thanks so if I'm reading that article right, only the 1.8" ssds use the 3.3v? So for your typical 2.5", these molex->sata adapters will work just fine? And those adapters look perfect for my needs. The molex cable off my Corsair 750m has 4 plugs on it, so can I use TWO of those sata adapters (same line, but in two separate molex ports), for a total of 8x 5400rpm drives? They will be the only devices on that one dedicated line.

Can you please link to someplace we can get such cables? Just spent forever searching amazon and it's hard to tell which ones are safe. *and is it safe to use these molex->sata adapters on ssds? I heard you lose the 3.3v pin (which some ssds use?)...

Gah ok guess that answers that then. Well I like the suggestion of using a Molex -> 4x sata adapter. My ps has a spare molex cable, and it would give me the extra length to reach this last drive bay. But can anyone point me to such an adapter that wont burn my house down?

Ok how about this, since I only have 2x 6pin -> 4 sata power coords, maybe two IS enough to power my entire array? Could I just get a couple of these splitters... https://www.amazon.com/gp/product/B0086OGN9E/ref=ox_sc_saved_title_1?smid=ATVPDKIKX0DER&psc=1 and divide the 15 drives (5400rpm WD 10tbs) between the two? So 7 drives on each? Is it safe to daisy chain that many sata drives? That would solve both my lack of a third cable problem and my cable length problem (since daisy chaining would give me just enough extra length). Otherwise, I don't see where they sell additional 6pin->sata power cables for my modular ps....

I have a Corsair CX 750M and I plan on running three power lines to each of the three drive cages (Rosewill server chasis L4500). That way, each line has at most 4-5 drives. Problem is, I can BARELY stretch to the middle drive cage. So I see three options... 1.) Daisy chain two sata power cables (I don't see a 1x female -> 4x male extension anywhere on amazon though...) 2.) Use a molex power cable, and then get a molex->sata adapter (effectively giving me a 2x length sata cable). Is it safe to do molex->sata power though? 3.) Get a dedicated 'extra long' sata power cable like this one... https://www.amazon.com/COMeap-Modular-Supply-Adapter-Mining/dp/B07PXBS54L/ref=sr_1_8?keywords=sata+power+cable+20&qid=1578786660&sr=8-8 *but that one only has 3 connectors so I will still need some kind of splitter... Non of those options seem great.... How are you guys powering drive cages that are far from your power supply?

Thanks for the info, just ordered and ASUS AM4 TUF Gaming X570-Plus MB... https://www.amazon.com/ASUS-TUF-X570-Plus-Motherboard-Lighting/dp/B07SXFK1TP/ref=cm_cr_arp_d_product_top?ie=UTF8 Which has SIX 4pin pwm headers! So instead of trying to convert the molex fans, I think I will just scrap them and go with these 4pin fans... https://www.amazon.com/gp/product/B07HC782D5/ref=ox_sc_act_title_5?smid=ATVPDKIKX0DER&psc=1 and I heard its safe to run two fans off one header as long as they dont exceed 1amp, so I got some splitters too. Now I should have all the control/monitoring I need right from bios/unraid right? No need for a hub/fan controller? Although that begs the question, I want these fans to spin up when the DRIVES get hot, not so much the case/whatever the fan headers are sensing. Can unraid do that?

So the 9211-8i I linked from amazon ($54) is a good buy then? And I just pulled the trigger on a AMD Ryzen 5 1600 AF (new 12nm version just released, seems to be getting great reviews). Just need a MB now. Since I saved quite a bit on the CPU, I'd like to invest a little more in the MB (definitely want at least three pcie slots for further expansion). Strongly considering 10g ethernet too (so I can possibly edit video files right off the ssd cache)... So any good MB recommendations? *oh and one other thing - am I going to need a video card? I would like to avoid it if I can (don't plan on doing any gaming/gpu work). But how will I do the initial setup?

Ah good catch, so the 512m cache is a BAD thing? So the 9211-8i = good, but the 9267-8i (with 512m) is bad? Looks like Amazon has the 9211 new condition, for the same price... https://www.amazon.com/SAS9211-8I-8PORT-Int-Sata-Pcie/dp/B002RL8I7M/ref=sr_1_5?keywords=8+port+PCIe+sata+Controller+Card&qid=1578522283&s=electronics&sr=1-5#customerReviews Customer reviews sound good. So is this the one to go with? *and there are no drive capacity/compatibility issues to worry about? Plan on filling the card with 8x WD 12TB drives.

Ok so for the sata ports, one of these... https://www.ebay.com/itm/LSI-9267-8i-6Gb-s-PCI-Express-2-0-512MB-8Port-RAID-0-1-10-SATA-SAS-From-US-Ship/192615863604?hash=item2cd8ccd534:g:S3UAAOSwDRxbYxl8 plus two of these cables... https://www.amazon.com/Cable-Matters-Internal-SFF-8087-Breakout/dp/B012BPLYJC/ref=pd_sbs_147_t_0/137-3624405-7210045?_encoding=UTF8&pd_rd_i=B012BPLYJC&pd_rd_r=0f71e415-9ec1-4226-a25c-dc2c5edb9779&pd_rd_w=j1m2Z&pd_rd_wg=Zbg3U&pf_rd_p=5cfcfe89-300f-47d2-b1ad-a4e27203a02a&pf_rd_r=S3D8DY7PVQ62Y4K2K1GV&psc=1&refRID=S3D8DY7PVQ62Y4K2K1GV That will give me 8 drives off the card, and 4 off the MB (with 2 free ports on the MB for optional 2x cache drives)?
