Boot Volume Condition: DEGRADED One or more devices has experienced an error IN SITU REPAIR?

[bitrot]

Afternoon all,

Crisis stations! Apologies if this has been asked elsewhere - I had a quick look at couldn't see the exact issue I'm having.

In brief I’ve been an idiot and not prepared for this scenario (let’s get that out the way now – 100% Mea Culpa)


I've logged into my FreeNAS box and found that the boot volume is degraded. I have no mirrored or backup of this boot volume.


Is there a way that I can recover from what I imagine is a disaster in waiting? i.e. I reboot and the FreeNAS box never comes back up again :/


What I'd like to know is can I:

1) attach a new USB stick to the live running system
2) backup the config & recreate an identical working copy of the degraded USB drive’s config (with ALL drives/shares/settings preserved)
3) remove the defective USB device and replace it with the now functional one
4) pretend that this never happened / learn from the experience and share my happy outcome with others


MUCH appreciated :)


Mr BitRot.

Easier than that:

1. Backup your config (http://doc.freenas.org/11/system.html#general).
2. Reinstall to new stick.
3. Restore config.

Is there an option to do a clone / config restore to newly attached USB from within the system whilst it's up and live? So very nervous about rebooting this box :/

Why are you nervous about rebooting the box? Do you have some sort of a complicated nonstandard setup?

If you follow the advice above, no data will be at risk. While you are at it, you might consider replacing the the USB stick with a small SSD as a boot drive. It will be more reliable.
