The Diddler posted:It looks like each fan has it's own power cable, so I would guess it's something like plastic epoxy gluing them together. I feel like if it was a bolt or screw, you would be able to see them. I found USB powered case fans for $15/each, or you could just splice a case fan to a USB connector and plug them in. I didn't realize they made USB fans; this will be perfect because my battery backup UPS will be right near it and it has USB ports! Thanks a ton!

Some of them were really old, so it's not like I suddenly had a huge problem, but I was moving house, so it was time to destroy them. I work in IT too, so of course I've encountered numbers of disk failures in my line of work. How many I couldn't really guess

Is there any trick to getting unraid to reliably saturate a 1G link on writes? Even a fast SSD cache drive doesn't seem to help. I had an old xpenology box that was like 10 years old that seemed to write faster.

I had a drive die when I shorted out the controller board (swapping the board let me recover data, those were the days), and a year old M2 SSD die that was in a laptop I only powered on once a month or so. I have had a ton of drives develop bad sectors, including both drives in my two bay NAS. The latter may have been a power cut, but the others never lost power and still did.

Chumbawumba4ever97 posted:Thanks so much for the replies! I actually have a bunch of drives already, so I don't need anything that includes them. OK so small update if anyone cares. I got this thing today and I have to say I am very impressed. I bought the USB 3.0 5 bay RAID version. The reason I bought the USB 3.0 version is I read the 3.1 version is simply 3.0 but with a USB-C cable  A few months back I had 5 of my 8TB Western Digital shucked drives completely die on me. As in, they stopped receiving power (no clicks of death or anything). I bought 5 8TB drives to replace them, then got to work trying to revive the drives. It turned out my old Antec EarthWatts power supply was somehow frying my motherboards, CPU, and finally my hard drives. After posting pictures of the PCBs on HDDGuru, it was determined that a small fuse on the PCBs on each one of those drives was probably the culprit. In what is most likely the luckiest possible scenario for 40TB of lost data, I was able to revive all 5 drives by simply adding a blob of solder to bridge the fuse. All 5 of them worked after that. This was my first and only time ever successfully reviving a dead hard drive. The fuse was way too small to replace for someone like me, so I decided to just leave the fuse "bridged". I know this is not a good idea, because if I my new PSU ever decides to fry these drives again, something more important is going to fry and they are probably toast. Not wanting to trust important data to these drives, I figured for the first time in my life I would actually back up some of my data (I have far too many full drives to back them all up); mostly the really important stuff like family photos or rare TV shows that are already on other drives. I was doing this by manually inserting one of the 5 drives into a USB dock about once a month, and copying and pasting the important files over to each drive. It was cumbersome and ridiculous to say the least. So I wanted a way to have all 5 of these "fuse bridged" drives to be always hooked up at one time. Despite never hearing the name Yottamaster ever in my entire life, I have to say I am quite happy with it. I used the dip switches to put it in "combine" mode and sure enough, after plugging it in I get one nice big 40TB drive showing up in Windows. It's also made entirely of metal (the texture is like what a MacBook feels like) and it runs very, very cool. I've been copying/pasting important files to it for over two days now and I am getting no warmth out of it when I touch it. It's actually cold! The only negatives I will say is that it doesn't seem to pass SMART data, so Stablebit Scanner is never going to be able to tell me if any of the drives plugged into it are on their way out. This doesn't matter to me too much though because this is being entirely used for backups of stuff that I already have on other drives. Also I am not sure if this is common or not, but I took one of the drives out of the enclosure and plugged it into my Windows machine and it would not recognize it. I was curious to see how this Yottamaster box organized the files across the drives but it looks like there's no way to find out. Anyway I figured I'd give it a quick review and from my short time with it, I like it a lot. Also since this is the first time in my life I am actually backing stuff up, I figured I'd ask; what does everyone here use as backup software in Windows? I think my old computer habits are showing that all I'm doing is copying and pasting files every month or so as a backup solution. Let's say this new 40TB drive is my Z:. And my drives with important data are the E:, F:, and G: drives. Is there some sort of software that will automatically copy all of the data from E,F, and G to the Z drive every X amount of days or something? Sorry if I'm describing it like an imbecile.

Macrium Reflect is the gold standard. Creates full and differential backups for free, incrementals for a cost. You can mount the images and browse the contents too. When you need to restore, it has a bootable USB image that you flash and point to your backup source. I have all my machines backing up to my UnRaid array and then shooting those up to Crashplan. Question about Macrium. Since I’ve started using Crashplan I have found that my backup frequency and their slow upload speeds (I have 50mbit up, they throttle like crazy) it means I never have my backups in the cloud. I have moved to monthly full backups and weekly differential, but still it’s too much. The Q: Is dealing with the differential and incremental backups the same as with the full? If I wanted to mount an image to browse how would I do so and include the dif/inc? So far I’ve simply mounted the full image in Windows and grabbed what I needed. Not sure if there’s another good way to do this. My thought is I can do fewer full backups (1 every 2 months) and pepper the diff/inc into Crashplan. I haven’t paid for the software yet, so haven’t decided if the incrementals are worth it to install on 5 machines.

If you move to incremental, you'll need every incremental between the last full and the date you want to restore. For differential, you only need the latest full and the differential from the date you want to restore. Incremental is smaller daily files, but you need ALL of them intact for a restore. For differential, you just need the one diff-file and the full.

Does Macrium only do partition and drive level backups, or can I somehow tell it to exclude a single folder and backup the rest of the drive? I've used it to transfer stuff between harddrives, but for backup being able to exclude unimportant things without redoing partition scheme would be useful. E: Nvm apparently that is a paid feature.

This is probably a ridiculous post but when I was plugging in the DC jack on one of my NASes I saw a yellow spark. I can't find anything wrong with the NAS and can access files on it OK, but is there anything else I should check to be sure? When the same thing happened on an external I had, I lost both the HDD and the enclosure.

Hey I need some goon help. Basically I have been using mobos with a lot of SATA ports for my NAS. I'd like to not have to find mobos like this anymore. Obviously I need a PCIe sata card. From what I remember I need an LSI flashed to IT mode (for doing software raiding). I need help selecting the correct card and cables. The OS will just be Windows 10 Pro and 10x Hitachi 4TB NAS drives. I would like about 12 SATA connectors... not sure how that is accomplished. Should I be looking at something like this: https://www.ebay.com/itm/LSI-SAS-92...eAAAOSwoZle8b81?

I’d like someone else to confirm that it’d work for your use case, but I’m nearly certain that it will. I’m using it on UnRaid and it worked out of the box, never checked or anything about ‘IT Mode’.

The "8i" in the model number means "8 internal ports." Each of the SAS connectors can accommodate a breakout cable with 4 SATA connectors. If you need more than 8 then you either need an additional card, or one of the "16i" models if you can find one at a reasonable price.

Yah agreed the DC can definitely arc a bit on insertion if there isn't a power switch on the device that controls the regulators. The best option is to plug into a power bar that has a power switch and then turn that on when everything is connected. The arcing won't hurt a well designed system behind some regulators with proper power control circuitry but it can cause scorch marks on a barrel style plug sometimes.

I got one of those $189 14tb Western Digital drives from Best Buy and the tests I like to perform before shucking a drive is to do a FULL format in Windows (this literally takes over an entire day to accomplish) and then run a deep SMART scan on the drive. However, for some reason I can't get this drive to show up in any of those programs. HDDScan 4.1 is the only one that even looks like it's going to attempt to scan it but it immediately shoots to 90% and then stays there forever when I try. Is there any reason the standard Western Digital "WD Diagnostics" tool wouldn't be able to see the drive? It's hooked up over USB, not some wacky interface or anything. edit: So this is interesting. This is the WD Diagnostics program that won't recognize the 14TB drive (but it recognizes all my other drives):  So I downloaded the WD Drive Utility program, which looks like this:  So I am guessing WD Diagnostics cannot detect USB drives, and inversely, the WD Drive Utility program ONLY detects USB drives. Anyway I am having the same problem with the WD Drive Utility program as I had with HDDScan 4.1. The "full SMART scan" shoots right up to 90%, and then stays there seemingly forever. Is something wrong with this drive, or is 14TB so new that they just don't really scan properly or something? Chumbawumba4ever97 fucked around with this message at 13:57 on Nov 30, 2020 |

Is there a way to swap out disks on a SHR array without degrading the array? I have a couple of free slots, so I can put in more drives, but can I would like to mark a drive for removal, mark a drive for addition, and have the NAS sync up the new drive and only remove the old drive when that is done, to avoid degrading the array.

BlankSystemDaemon posted:If you're asking whether the XOR function (which is used to provide one disks worth of distributed parity for striped disks, ie. equivalent to RAID5) can somehow be zero-copy switched to a Finite field (assuming SHR2 relies on Reed-Solomon like every other RAID6+ implementation) based mathematical function, then no, that's not possible. No - I am asking something else. If I have a SHR array of 5 x 8TB, and want to switch to say 5 x 14TB, I could take out a 8TB drive, put in a 14TB drive, and rebuild. Then repeat for each of the other disks. This means the array doesn't have redundancy for 5 rebuild cycles. I want to be able to tell the NAS to clone the 8TB drive onto the 14TB drive, and keep the clone in sync as needed as data changes, and then once the clone is complete allow me to remove the 8TB drive from the array without causing the array to degrade (since the new drive is identical to the one I am removing).

All the recommendations involve pulling a drive and then rebuilding. While that would presumably be a slower process than a simple copy job, it should work fine. Unless you add new data to the array during the rebuild, even if there's some error somewhere along the way I'd think you should be able to pop your old drive back in and it should go back to a Healthy state.

Ya I didn't find anything either, but thought there might be a way I missed. Hmm, so the OS isn't on the raid itself?

I'll admit I'm not sure about where exactly the logs are stored. In that I've yet to see anyone mention an option that isn't pull a drive and replace sequentially, I'm not sure you really have much of a choice other than rolling the dice with it anyhow. Or finding space somewhere to have a complete backup.
