I transitioned to internal boot by using my single nvme cache drive as a boot+data partition and I i thought i would add a second drive for a redundancy since intel optane drives are so cheap. I added the Optane drive just now but neither the Onboarding Wizard or the Internal Boot Wizard in Tools gives me the option to add it.

Am I stuck with just have a single boot drive or is there a way around this?

Thanks

All you have to do with the array stopped is click the disk count dropdown, and set from 1 to 2 and then assign the 2nd disk. Unraid will do its thing and you will have two disks available for use as a boot pool.

It looks to me like it's just going to create a cache pool rather than boot?

The drive is for both parts. Each is a partition, data part and boot part.

Thanks. When I tried to add my 16gb Optane drive it said it was too small, it’s only showing as 14.4gb in Unraid.

New device must be the same size or larger than the old one.

So I cant use a 16gb Optane drive with a 16gb partition because the partition is from a 500gb drive?

Correct, you can't have only the boot partition mirrored, has to be the whole boot+data.

Not with a data partition; you can if you erase that first and the boot partition is the same size or smaller than the new device (any data there would be lost)

Sorry if i’m being a bit of a noob (i am) but currently i have a 500gb NVME that has a 16gb partition used for boot and the remaining space is used as my cache drive, what would i need to be erasing in order to use my new Optane drive in a boot mirror?

Also, the onboarding wizard said that 16gb is the minimum required size for a boot partition and while my Optane drive is 16gb its only showing as 14.4gb in Unraid despite being brand new so maybe it wont work no matter what?

You would need to erase this.

8GB is enough for a dedicated boot pool (but you still cannot add a smaller device to an existing one, e.g., if you had a 16GB dedicated boot pool, you could not add an 8GB device; you could the other way around)

Ok, thanks. If i cleared my cache how would i then go about re-doing my internal boot setup? At the moment if i use either the onboarding or internal boot wizards it doesnt give me the option to re-configure it since it has already been configured.

Would I need to use the USB tool first and then do what you say in the link you posted?

If you don't have a flash drive with the same release you are running, then yes, first create it with the USB tool, then continue the other steps.
