Sorry, I forgot... The missing parity drive is a Seagate 16TB disk - ST16000NM001G-2KK103_ZL28MF9F thor-diagnostics-20250418-1521.zip

My electricity supplier has changed the electricity meter and my Unraid server has been switched off unplanned due to the power failure. When I restarted it, there was a red cross next to the first of my two parity disks. “Spinning up the hard disk was not possible. But I could still see the hard disk. I then started the array and did a parity check, which resulted in a “0” error. I then rebooted the server again and then the one parity disk was completely gone and it is no longer visible in the gui. Can anyone give me advice on how to recognize or even revive this hard disk? I have ordered a new hard disk to be on the safe side...

Well, after several reboots and stuff no change. The gui (webserver?) side does not work properly. Emtpy pages. Only several browser reloads make the gui pages appear. Plex over web displays the gui but cannot play back films via webbrowser. Shares are working. Plex is working in connection with the plex apps on iPad and Apple TV. Very strange. Guess I have to wait for the next update to fix this.

Seems to be the same issue I have since patching.

OK I misunderstood you remark. I'll plug Screen into the server and will look into it.

I did a reboot. Incredibly slow. Several reloads of the page makes it the complete gui finally apear. I can see that I have barley load on the CPU but the webserver seems to be slow as hell. Secure reboot did not help.

I installed the latest patch (Unraid 7) and now I can barely reach the gui. Mostly empty pages after login. Anyone here with the same problem?

I have two of these SUPERMICRO SUPERCHASSIS 743TQ-865B-SQ server towers. They were advertised as "low noise"... Well the are not. Since the build quality is excellent I'd like to keep them but I want to get them less noisy. The included hot plug fans behind the backplane are pretty loud and cooling isn't too good anyway - I guess because those fans are small. Did somebody here modify a Supermicro chassis to make it "low noise"?

Thank you very much!

I want to upgrade my Unraid Server with a modern HBA which is also capable to work with NVME (U3) and PCIE 4. Those are expensive but should work for a longer timespan. I found this one: Broadcom 9500-16i HBA 16-Port SAS/SATA/NVMe Is this one fine or does anyone have a better suggestion?

Asustore even made own videos how to install Unraid:

I read in. the net that it would be possible to run other OSes like Unraid on Asustore NAS Hardware. Those are basically PCs and you can get into the BIOS. Did somebody here try this out? They have a 12 NVME SSDs only / 10GB NAS in the program and I am very tempted to make an Unraid server out of this thing. https://www.asustor.com/de/product?p_id=80

I know this post. And your contributions to it are appreciated. But this is basically what I was describing. There are several solutions in this post and you have to invest hours to figure out what works and what does not work. Many users are not software engineers or unix experts. We need a definitive solution by Limetech how to make this work. And this should be sorted by macos version and Unraid version since there are all kinds of problems caused by different software versions. There are also tweaks on the Mac side that should be described in one place - documentation or sticky post. And to my knowledge the main issue with this has not been addressed so far - the most time consuming part when copying files from Mac to Unraid is the moment when a file has basically been copied the the server and then some kind of halt / pause is happening - sometimes for over a minute - until the next file is copied to Unraid. Copying hundreds of small files becomes unbearable by this behavior.

I don't know how many postings in the forum and on different websites I read to figure out how to get some acceptable performance when using macos with unraid. Still accessing folders on an unraid server with a mac needs real patience, the write (and read) performance simply sucks - sorry. Sometimes I "peak" to 60 mb/sec but most of the time I am around 25 mb/sec or "0"mb/sec when writing a file halts for some time (for whatever reasons). Also we have some degrading effect over time: A new booted Mac gets slower over time with copying files to unraid. With my PC on the other hand everything runs smooth and fast. And on my Synology box I also have no samba issues with the mac. I tried out all kinds of suggestions here in the forum. Some made things better, some worse, some didn't work at all. This problem is meanwhile lasting for years - and as much as love the helpful community here this is not a problem the community has to figure out. What is really needed is a "sticky" post here straight from Limetech with a definite "how to" for samba settings for mac use. And if samba is not useable for the upcoming future then give us a workaound with NFS and a "how to" for those shares (I have tried this but performance seems to be even worse).

Der Durchsatz ist im normalen Array fast egal es sei denn Du hast mehr als 1 gigabit Ethernet oder wills 'mal mit ZFS herumspielen. Du kannst Unraid ja so konfigurieren, dass die HDs "schlafen" gehen, dann ist der Stromverbrauch erträglich. Was die Temperaturen angeht, so ist meiner Erfahrung nach das Hauptproblem, dass bei vielen HDs sich die Wärme irgendwann im Gehäuse zu stauen beginnt. Und dann kommt man recht schnell über 50 Grad und wenn das dauerhaft der Fall ist, dann gehen die Platten schneller kaputt. Wenn Du beispielsweise regelmässig die Parity überprüfst und alle HDs gleichzeitig über einen langen Zeitraum am Start sind, dann wird es zügig sehr warm / heiss.
