Recover config from USB

[boota]

I've had a working FreeNAS system for a 1+ years. Upgraded to 9.3, everything working great. Due to some power issues my machine fickered off and on a bunch. Now the USB boot drive I was using appears to be hosed....the system will boot up to a point (just past networking) and eventually turn off.

To test hardware vs software, I used a fresh install on a new USB drive and the system is fine.

I'd like to understand what process I might go through to recover the configuration from the old USB (if its possible). I can use the old USB to boot to single user mode fine and can see the configuration db on /data. However, I can't quite piece together the steps to get that file into the fresh install. Would love a suggested set of steps, other ideas on how to recover.

thanks

and yes- I've learned my lesson- mirrored USB boot drives.

One possibility is to boot the new disk, log into the shell, and take a look in /var/db/system. You should see a bunch of database backups (hostname.domain-yyyy-mm-dd-nn.db). Pick one from before your problems, copy it to an accessible location, and upload that through the web GUI.

I'd also recommend investing in a UPS.

Thanks for the response.

I don't see the system dir in /var/db. When you say 'boot the new disk', you're referring to the fresh install on the new USB, right?

fair enough- thats resolved as well already. The old one had failed and just not had time to replace it.

I was, but I'd missed something in my reply. For that to work, you'd need to auto-import your pool and tell your system that the .system dataset is located on your pool.
