I have an Intel Optane drive that I just installed in my system, but when I tried to format it it failed saying to check the SYSLOG. I collected up a diagnostic before shutting down the system to try installing it in another and it worked perfectly fine in that one. I have tried a different M.2 slot on my motherboard as well as a PCI to NVME riser and it failed in both of those. I’ve attached the diagnostic file and hopefully something jumps out as the issue.

Your diagnostics show the drive itself is not the problem. The partition table was created successfully, but the format failed because the plugin is trying to execute:

/usr/sbin/mkfs.exfat

On current Unraid releases, mkfs.exfat is actually located at:

/sbin/mkfs.exfat

The important line in your log is:

Format failed: sh: line 1: /usr/sbin/mkfs.exfat: No such file or directory

So the partitioning completed successfully; only the filesystem creation failed because the executable path is incorrect.

Thanks for looking into this. I’m assuming I just need to wait for the next version of the UD plugin to be published?

Thanks. I installed the three Next plugins from your GitHub and I was able to format the drives now. More out of curiosity, but will these Next plugins replace the Unassigned Devices plugins listed in Community Applications?

I really advise against installing plugins outside of CA as there is no validity to those plugins. Considering they run directly on your system.

While I do have trust in the work which @dlandon provides the Unraid community, I am in agreement with @MowMdown 's concerns.

If this was some random plugin, I would recommend not installing a plugin from outside the vetted Unraid Community Apps. But the Unassigned Devices suite of plugins are pretty much essential to most Unraid users.

Now that @limetech is the owner/author of these plugins (due to unfortunate circumstances) I would hope that, in the future, they would check that any ancillary programs test okay without any breaking changes before releasing OS updates. If issues are found, they should make any required updates and release them to the CA, and perhaps even add these to the plugin checker which runs during the update process.
