November 28, 201510 yr I recently set up unraid to replace the main OS on my desktop so I could run multiple OSes without more hardware. Everything is working great except for the cache drive where I have my main VM disk located. After rebooting, the array starts just fine but the cache drive is listed as 'new'. All the data is still there and everything works like it normally does if I re-assign it and start the array. The cache drive is a recycled Cache Mac book air SSD (SM128C).

Net result (and the reason why you have to keep resetting the cache setting) is that you can't write to the flash drive. I would pull the stick and toss it into a desktop and run chkdsk on it, then reboot unraid. If the settings still won't stick, try a different USB port (ideally one on a different controller -> if its plugged into a USB3, plug it into a USB2 and vice versa)
November 28, 201510 yr Author The usb drive is fine, it is the usb 3.0 pci-e add-in card that seems to have had a fault. But there were issues before then. I will reboot and then post an updated syslog.
November 28, 201510 yr Author I had to re-assign the cache drive again, even after using 2 different usb drives. See attached diagnostics share-diagnostics-20151128-2307.zip
November 28, 201510 yr Community Expert This happened to me once and got around it by using a different browser to assign cache and start array, then continued to use old browser (chrome in my case).
