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. This has already been corrected in the current UD Next code.

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

The issue has already been fixed in Unassigned Devices Next, which is an independent continuation of the original Unassigned Devices project.

If you'd like to use the fix now, install both Unassigned Devices Next and Unassigned Devices Plus Next. Installation instructions and releases are available here: https://github.com/dlandon/unassigned.devices-next

The Plus plugin provides the formatting support, including exFAT.

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?
