I'm on TOS 5, I've added a brand new NVME for hyper caching after Volume and Storage Pool were created.
The button to create a hyper cache would allow me to create one but would fail.
I restarted the NAS and now it is stuck in a "Hyper Cache not created!" and the "Create now" is disabled
The "mount" button on the top right is available, clicking that brings to mounting the SSD cache. The next and cancel buttons are not in English, appear to be in Chinese.
Mounting the SSD cache, results in a "RAID error" but not much information from that.

NVME is not part of storage pool, or volume. It does appear in disk.

I've checked out other threads, but nothing so far relates. Could potentially be a partition, have not checked that but I can no longer even attempt creating hyper cache, so was hoping I could get help understanding that first.

Did you ever figure this out? I have same issue and I can't seem to find a clear guide on how to install hyper cache on a M.2 NVME disk.

Which version of TOS 5 are you using? If it is not the latest version, it is recommended that you update to the current latest version of TOS5:

If you try and still can't get it to work, you can contact the homepage customer service or technical support e-mail for help.

Thanks for this information. I reset everything and decided to just turn my nvme drives into a raid 1 boot/system drive. I didn’t think it would gain much using them for cache.

thanks for share
