Boot Pool Error 'Write Protected'

[seb101]

Hi,

Today I got a notifcation that my Boot Pool was degraded due to the failure of one of the devices. I was somewhat surprised as this USB has only ever been used for FreeNas and is only about 3 months old. So I attempted to scrub the pool to bring it back however I get the following error:

Code:

Is this an expected error for a failed USB? Or is there something else likely at play here?

Can I try anything to bring it back? Or is the only solution to buy a new USB?

Thanks!

Scrub won't fix a single drive (without redundancy) . Try to save the config. Install FreeNAS from scratch on another drive (small SSD is a more reliable option). Import the config file and you will be good to go.
