Upgrading USB boot to SSD

[moelassus]

I finally got around to ordering a pair of inexpensive SandDisk SSDs to use as my boot volume. I nabbed a pair of 120GB drives for $25ea at the local MicroCenter. Seemed like the best deal I could find anywhere.

I had read an old thread that recommended attaching the SSDs to the boot volume before removing any of the USB drives. I tried doing this and I receive an error
[MiddlewareError: [EFAULT] 3-way mirror not supported yet]. From the older thread it appeared that the original poster had been successful doing this.

I will go ahead and proceed with removing one of the USB drives from the mirror and try to add an SSD but I was curious if I was missing something?

Thanks

Well I managed to mess that process up and I have no idea what I did wrong. Here is the process I used.

I went into System / Boot / Status selected one of the USB drives and chose Replace. I picked one of the SSDs and waiting for it to return that the volume was normal. I even double checked from command-line that everything was OK.

Then I did the same thing for the second USB drive. I received an alert that there was an unrecoverable error. I ran a scrub and received more errors and it now tells me.

Looks like I've earned a reinstall. I did grab a backup of both the config and the encryption key. I'm curious what I did wrong. Both SSDs passed the Long SMART test without error.

Thanks
