Boot device failed, replacement was DOA, boot pool status is "replacing" and new device won't attach

[Ben Waywood]

I had 2 16GB USB drives as a mirrored boot environment, one boot device failed, when I attached it to the environment it worked for a few hours then went back to degraded so I assumed it was DOA, since then the boot pool status is "replacing" and the new device won't attach

Boot Pool Status

freenas-boot000DEGRADED
replacing000DEGRADED
/dev/da0p2000ONLINE
/dev/da0p2000UNAVAIL

Error after attach attempt

Thanks for replying, unfortunately I am still facing this issue.

Does a fresh install to a new boot device resolve the issue? If so, you can restore your config.

I am going to do that next. Can you confirm that if I go to System > General > Save Config then to a clean install and go to System > General > Upload Config it will restore everything including plugins, jails, VM's? Or is there another step to ensure everything restores correctly?

If you leave your data drives in the system, it will work as you describe.

I am back up and running now, there were a few dramas and I ended up using my windows machine to format the boot drives and had to try the install several times but eventually, it went through. Thanks for your help
