I reached out to Unraid support. They were super helpful and saw errors that looked like hardware but could not identify the culprit. After BIOS updates and testing RAM, Intel 13th gen CPU, and hard drives I could not find an error. One of my hard drives dropped when I temporarily removed my HBA from the system. I changed out the cable from my HBA to a bank of SATA hard drives. No luck but I was able to move a small amount of data. I finally found the real issue regarding my array. One of the three RackChoice Internal Hard Drive Enclosures created errors to all connected hard drives. Here are a couple things I have learned. Rufus will make a Windows boot USB but will not make USB bootable Windows. Hasleo WinToUSB will do this. The software is free if all you need is Windows Home Edition Intel has a tool to test their processors. The Intel Processor Diagnostic Tool only works under Windows. If you want this to run from a USB Flash drive see Hasleo WinToUSB Memtest is built into some BIOS these days. It is super handy. I used it when I bought the hardware and almost forgot it existed.

One of my Unraid servers has an issue. The array becomes unresponsive if parity check, mover or writes go to the array. The system will, in fact, become more or less unresponsive if any writes occur. Reading files from the array via SMB or Docker containers such as Duplicacy backup or Plex are fine. The ZFS cache pools seem to work fine. I ran short SMART tests on each drive as successful. I am in the process of doing extended SMART tests but this will take time with 13 total hard drives. I did try the Live Memory Tester plugin to create a 100GB test of a total of 128GB RAM with no issue. I will run memtest from the USB Flash after all the hard drives are tested. I would be grateful if the community would give me any further suggestions. marvel5-diagnostics-20251028-1642.zip

Why does Unraid not have a list of known good and greatest USB drives? It seems as a paid product this kind of testing would justify an ongoing commitment to it's customers. I am not shitting on Unraid. I think this question is quite valid, as I am again searching as another USB drive is failing

I can confirm that the array operation was completed minutes ago adding a drive to the array on the target Unraid server. I then added the NFS share back on my servers utilizing the share. It is added perfectly and the used and free is accurate. Every pissed-off service has been restarted, and I can confirm happy again. So the target Unraid server adding a drive to the array is confirmed to have the issue.

I have a similar issue while running Unraid 7.0.0-beta.2. The remote servers can log in and supposedly mount the NFS share. The share shows as O B used and 0 B Free. I am trying to self-diagnose the issue. I am leaving this here as an FYI. If I learn of a fix I will leave it here. Sadly, my server is clearing a newly added drive. I can't move forward to resolve it. This means many services running on other Unraid servers cannot reach the data and therefore are not functioning. I re-read the posts in this thread and tried /usr/local/etc/rc.d/rc.nfsd restart on all the related servers. That did not fix the access.
