🙄😒 My luck continues. It is a pity, these were good drives and bought new... but they have been lying dormant for a while. I will try and have a run at them with some software and see what is what. Ta, again, Jorge.

I actually dragged that drive out and replaced it again (I have two microservers and 8 drives, now 6). I SMART tested the third drive and it came back sound and am rebuilding/doing parity sync with the third drive. Will the diags still be relevant or have I effectively wiped them? eaufarm-diagnostics-20221104-1100.zip

Crikey... I am still having problems. I swapped out the parity drive with SMART error showing... and replaced it with a drive of exactly the same type and age. I did not know if there was a certain protocol or way that I should do that... so I took the array offline, turned the server off. Replaced drive and then turned everything back on. On the "MAIN" page of Unraid I then assigned the new drive, in the drop down menu, as the new parity drive. I then hit "START" so that it would do a parity check and rebuild the array. This it did overnight. I now have green everywhere on the dashboard.... but... When I run a SMART self test it comes back as "READ FAILURE". But it does not turn amber. Extended tests complete almost instantly... and short tests run for a while, but then return the same result. But it all comes back green, ie it does not turn amber. Is this another bad drive, or something else at play here?

Cool, Thanks Jorge.

Nope, after. So, on the back of our discussion I started the array, formated the drives and then did an extended test. It returned with read failure.

I will start a parity check but it will take 6 hours

The last extended test completed with read failures, but the parity completed and is valid.

So, the pending sector errors are gone, as you described. The one that has remained is the #187 reported incorrect error. This has a RAW value of 1. https://www.backblaze.com/blog/what-smart-stats-indicate-hard-drive-failures/ I am reading up trying to understand what it all means... and the guy above talks about it. There is one side of my mind which says... it appears to be a singular error and that in and of itself it is probably one of those things and it is fine. The other side of my mind says... well, this is the parity drive (is it more serious if the parity drive fails?), it is not for me but a close relative, they are storing data which is highly precious to them, it could be an indicator of future trouble, ideally you would want to start of with no errors and it might be easier to nip it in the bud now. But it is hard for me to make a call, because the word "error" is, due to my ignorance of servers and Unraid and SMART, highly emotive. This might be nothing to worry about.

I think the problem is that this is the server for my father. He wants something to back his photography up to. The disk displaying a SMART error is a visually discomforting thing. Obviously because these are "new" disks (2 years old, but not been used for anything) it should not have any errors. So, how important are SMART errors? Like, is this server actually fine and dandy, but just has a single bad sector and should be good to go? Or is the error a signal that there is something wrong on the drive that could, potentially, lead to my father losing data later?

Hiya, So... I started the Parity Sync, which was all successful. Then I formatted the remaining drives and ran another SMART extended self-test. Still came back with one error on the "Attributes" tab and shows it is a drive with errors on the dashboard. Should I replace the drive to be safe?

Lovely, thank you

Hiya, Well... I ran the extended SMART test last night in response to it showing an error. When you say "sync parity", how would I do that? By starting the array? (I did not start it cos I had a disk showing an error) or is there a link to a webpage that will give me instructions on how to proceed. I really want to master small servers and Unraid, but right now I feel a bit all at sea. Thanks for your advice.

Hiya, I have read the link and assume you want the zip file? Many thanks eaufarm-diagnostics-20221102-1137.zip

Hello. First off I should apologise. I am a bit of a noob and I have tried searching the forums for an answer to this... so, I know this is basic. But I am not finding an easy solution on my own. A couple of years ago a friend encouraged me to build a basic server into a HP Microserver and, at the same time, I built one for my father. Well, I never finished the project before the pandemic hit and I have lost contact with that friend. So, these servers have lain idle for a couple of years. I used WD 4tb Purple drives and they were bought new. Now, I am upgrading my fathers PC and he wants to get his server up an running and so I am trying to get a basic understanding of Unraid and get these servers going. Now... On my fathers server the parity drive is displaying an SMART error. I have run self-tests... I have tried reseating it and cleaning the contacts. It looks and behaves like a new drive, I have tried reading the attribute page, etc. I dunno whether I should try to reformat it (although I cannot find how to do that... in the forums the displayed screenshots seem to have different buttons to me)... And I dunno whether to replace the drive and not use it (it being my fathers server I do not want to make a mistake and ingrain a drive failure). If the drive is faulty, I will swap it out... but it should not be (in an ideal world) and whatever ails it... it does not seem to be a big thing, so if I can fix the error it would provide some peace of mind. Again, I know that this is a little basic and so I thank anyone/everyone for their time and replies.

Hiya, Yep.... been constantly checking spam. In fact it was a shock to me that it has only been 10 days since my original post, as the constant checking of spam has made it feel like a lot more time has passed. I should say, as well, that if Limetech were to refuse my request.... no worrles. Hard lesson, but ultimately the mistake was my own. It is the lack of reponse either way (in fact at all) that is keeping me in limbo. Cheers for your reply.

Hiya, I understand that UnRaid is not exactly operating at Apple/Microsoft levela of employees, and that we are living through Covid times, but... Does anyone else have trouble contacting UnRaid? The (boring) story here is I fundamentally misunderstood the licensing model which I learned about here: https://forums.unraid.net/topic/93865-trouble-applying-owned-license-to-a-second-proliant-microserver/ Since this post I have emailed UnRaid twice asking if there was anyway I could change from a 1 x UnRaid Plus to 2 x UnRaid Basic. But I have had no response. I do not mean that I would expect to, necessarily, have this totally resolved by now. It is just that there has been NO response... complete static. Are there UnRaid staff here that I could talk to? Am I being a bit impatient and should wait a bit longer? I am sure I will get something... (ie I am not panicked about this) I just wonder if there is a better way to go about it. Thanks for your replies.

Sod. I did not realise that, I will have to contact support. Many thanks for your reply.

Awwww.... I know it is my fault, but I did not realise that about UnRaid. I cannot afford to register and pay for an entirely new license When I bought the Plus license I bought that thinking that I could register multiple devices across servers. I wonder if they will refund me and allow me to by two Basics? As the 5 drives per Microserver is the maximum I could have anyway. Thanks for your reply.

Hello, So... I am a "total noob" when it comes to UnRaid and to servers. Essentially I was looking to buy a NAS and fell down a rabbit hole (with a hefty push from a friend) when I was introduced to HP Proliant Gen8 Microservers. I have one set up and populated with disks which is a Plex server and I am building another for back up purposes. I went ahead and purchased an UnRaid Plus license key to allow me to have 12 drives attached - I actually thought that that would allow me 3 microservers, but I forgot to count the SSD I installed as a device, doh. No worries though.... I can still have two microservers, which is enough for now. *** Business*** So, today I set up the second microserver and installed the UnRaid OS onto a USB drive... I have booted it and tried to set it up from memory, last time I had more help from the friend mentioned above. The first thing that I did was to enter my UnRaid Server OS Plus Key..... however.... that did not go well. In essence I got this message: "The registered GUID does not match the USB Flash boot device GUID The Registration key file does not correspond to the USB Flash boot device. Please copy the correct key file to the config directory on your USB Flash boot device. If you do not have a backup copy of your key file, Contact Support. If you want to replace your Registration key with a new key bound to this USB Flash device, click Replace Key below. An original key may be replaced anytime. Thereafter, a replacement key may be replaced again after one year has passed. If you require another replacement key sooner, Contact Support. Note: Replacing a Registration key results in permanently blacklisting the previous USB Flash GUID." So, my question is.... have I effed up? And is there a simple guide on how to fix this, without blacklisting anything? Thanks for your help.
