Boot volume degraded: replacing a usb stick.

[Lucas Damaceno]

Hello,

So I have a failed USB stick in my Supermicro SSG-5048R-E1CR36L

I am using 2 SanDisk Ultra Fit 32GB

NAME STATE READ WRITE CKSUM

freenas-boot DEGRADED 0 0 0

mirror-0 DEGRADED 0 0 0

Just to test I tried to do a fresh installation (with a new one usb stick in another computer), then plug on a test server and do the normal replacement process (go to system > boot > status and click replace) and then use this new one resiveled to boot. But was not possible to do it by itself, it showed me only a black screen, but if I use the old one the boot is working normally. Could anyone explain me? I tried it with a new usb stick empty it does not work too.

I have read here, the most recommended process is fresh installation and then restore the config, right? But my supermicro server is running in production mode, so I wouldn't like to shutdown to do the fresh installation process. Is it possible replace a usb stick without shutdown the server and be sure if the old one usb stick fail it will be keep working?

You can replace the failed boot drive in the system tab of the GUI. It's documented in the manual.
