Boot device failing - Save config question

[Mitch72]

Hey all,

Random question here, had a search but couldn't find anything just yet.

My boot USB is currently failing with a bunch of checksum errors during scrub, and I don't have a mirror.

I have a recent config backup, but it is a few days old and I have made a few minor changes since them. I was wondering since the system is still up, would if be safe to save the config now? Or would it be corrupt? Alternately, could I mirror and replace the drive now? It's not a big drama if I need to reinstall from the older config backup, just would save some time.

Output from zpool -status below:

Code:

pool: freenas-boot
state: DEGRADED

status: One or more devices has experienced an unrecoverable error.  An
		attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
		using 'zpool clear' or replace the device with 'zpool replace'.

Thanks,

ZFS is telling you there's no corruption for now so you can backup your config file no problem.
