Thanks a lot, I will keep you updated if I need more help, but I would also like to see if it would be fixable and if it isn't fixable then maybe put up a guide saying that there is no point in trying to fix this (insert good searchable term/keywords) and then follow the info you provided me with and some kind of explanation?

So, I got those 3 foldera on disk3 that "don't exist" anymore and I've tried deleting them with rm -r /path/ but then I get input/output error.
They look like this when I do a find or ls -al /path/
find: `/mnt/disk3/UnRaid/ssss': Input/output error d????????? ? ? ? ? ? ssss/
at the same time my log shows me this
Nov 4 11:12:41 KL kernel: BTRFS critical (device md3): corrupt leaf: root=5 block=695271424 slot=112 ino=87804, name hash mismatch with key, have 0x0000000024f576f0 expect 0x000000008115b321
So at the moment I am unable to access my files in the Share "UnRaid" because of this.
I did a filesystem check, first read only, then repair and then read only again and it looks like this

Then I did a btrfs scrub that looks like this
scrub status for 89b48731-b52c-40a3-9cae-2e756f837851 scrub started at Sun Nov 4 06:41:13 2018 and finished after 02:06:48 total bytes scrubbed: 1.30TiB with 3 errors error details: csum=3 corrected errors: 0, uncorrectable errors: 0, unverified errors: 0 The log showed this during the scrub Nov 4 06:51:16 KL kernel: BTRFS error (device md3): bdev /dev/md3 errs: wr 0, rd 0, flush 0, corrupt 94, gen 0 Nov 4 07:47:42 KL kernel: BTRFS error (device md3): bdev /dev/md3 errs: wr 0, rd 0, flush 0, corrupt 95, gen 0 Nov 4 08:47:59 KL kernel: BTRFS error (device md3): bdev /dev/md3 errs: wr 0, rd 0, flush 0, corrupt 96, gen 0
My fs df looks like this

And lastly my btrfs dev stats /mnt/disk3
btrfs dev stats /mnt/disk3 [/dev/md3].write_io_errs 0 [/dev/md3].read_io_errs 0 [/dev/md3].flush_io_errs 0 [/dev/md3].corruption_errs 96 [/dev/md3].generation_errs 0
So can you please help me make sense of this all?
I've googled and searched the forums but couldn't find anyting and I'm unsure if those 2 issues are connected or not.
Where do I go from here to fix this? I work in IT as support and mostly MS platforms so my *nix knowledge is limited and therefore I don't know how or what to ask.
If I happened to miss anything pleas tell me and I shall provide. And no I do not have ECC ram but I've done memtest86+ for a period of 43 hours please see picture, my PSU is good as well 750w 80+ gold.

Yes that's what I did exactly
but nothing displays under nut details and nut setting status is still stopped but the log says :
May 8 16:16:35 Serveur usbhid-ups[1179]: Startup successful May 8 16:16:36 Serveur upsd[1188]: listening on 0.0.0.0 port 3493 May 8 16:16:36 Serveur upsd[1188]: Connected to UPS [ups]: usbhid-ups-ups May 8 16:16:36 Serveur upsd[1189]: Startup successful
I just setup my first ups a Eaton 5S via USB and I got it to work with the manual configuration like this from the auto-detect:
driver = "usbhid-ups"
port = "auto"
vendorid = "0463"
productid = "FFFF"
product = "5S"
vendor = "EATON"
bus = "005"But I wasn't pleased cause I could choose the usbhid-ups driver in the auto conf but it still didn't work, so I tried to start it via SSH and it always said, you need to name port = in the usp.conf so I went into the editor and did that and started the script via SSH again and same error message so I did that a few times and didn't understand why, until I figured out that I needed to WRITE MANUALLY "auto" in the auto conf script above where it asks for UPS Port: and that's where you write auto so it will write it into the ups.conf and then it worked.
My question to the dev is, why isn't this by default already filled in with auto?

I have a problem with that, because the datasheets for the two models (namely, ST8000AS0002 and ST8000AS0022) are very different, in particular with respect to the newer drive's implementation of ZAC. Where there's a disagreement between a level 1 tech support operative and the official manufacturer's documentation, I would tend to go with the latter. Reading datasheets could be thought of as "doing one's homework". I'm not disputing your V1 vs V2 vs V3 findings, just the suggestion that the AS0002 and the AS0022 are "the same".
EDIT: Here are the links to the datasheets:
ST8000AS0002 (I can't find it on Seagate's site any more, so this is a link to my Dropbox copy)
I was trying to find the ST8000AS0002 datasheet but was unable to find anything on their page but it may be that they have implemented the ST8000AS0022 features as they are linking to the new datasheet on the ST8000AS0002 drives page and that they may still be producing them with the old model number.
But I hate to speculate on that and will try to get in touch with someone with a higher position than 1st-level support.
Thanks for furthering my thought process and teaching me not to believe everything I read written by a company's tech support.

I finally have one of these.
My google foo is failing, what is the difference between a V2 and a V1 of this drive. The adverts all put V2 in description (Seagate Archive V2 8TB 128MB Cache Hard Drive SATA 6Gb/s 5900RPM - OEM) but I can see no information anywhere on what a V1 drive was or how to identify it.
V1: ST8000AS0002
V2: ST8000AS0022
Differences:
https://lime-technology.com/forum/index.php?topic=47509.0
I will write the same as I did in the post linked above so you don't have to jump all over the forum and that you should do your homework before believing and taking things as a fact.
As I was curios enough to ask Seagate directly and if they could tell me the difference between the ST8000AS0002 and the ST8000AS0022 drive and which of them is the V2 and which is the V1, if there ever was a V1 or that the AS0022 is actually a V3 and the AS0002 is the V2 cause V1 never existed.
This is the answer I got from Seagate:
Thank you for contacting Seagate Technical Support. I understand you are wanting to know the difference between the model numbers. The drives are the same but they are given different part numbers due to when they where made or what region they are sold in. There is no difference in the details of the drive other than that.Kind regards from me and Seagate,

You might ask why I did what I did? It was because I bought one of those 8TB SMR drives 3 weeks ago and I'm using it as my Parity drive, so it was sold as a V2 but showed the AS0002 and from what information I could gather is that it was a "V1" according to the information available on the internet and on this forum but it all was speculation.

(SOLVED) Input/output error or btrfs leaf corrupt
in General Support
Posted
Yeah the --repair shouldn't be shown when you press "help".
A guide on the forum where it says "btrfs leaf corrupt or similar issue like that, do this cause X is not easily fixable and therefore this is the easiest/best solution".
