August 29, 20223 yr As the title suggests my server has been running for a while now, but last night i had a power outage and now it gets stuck on the "unable to mount root fs", ive been looking around on what the issue might be/how to fix it but nothing has seem to come up. I have seen making a new usb and copying over the config, but everytime ive tried it hangs on copying "unraid-api.tgz", if there are any solutions any help would be apprciated!

It sounds like some files on your flash drive have become corrupted (can happen with power outages). Your best bet is to create a new unraid flash drive and restore config folder from a backup if you have it. You could probably get away with reformatting/recreating unraid files on the existing flash drive unless it is physically damaged in some way.

I don't believe i have a backup(stupid me), i can get into the drive completely but as i stated when i attempt to copy the whole config folder over it always stops working when it tries to copy "unraid-api.tgz", im compeletly okay with having to re add my plugins etc if need be on a new usb/the same one but i just dont want to have to re buy an unraid key again, if i just need to copy the key file over for it to work im happy with that, ideally id like to just copy it all but it doesnt seem to allow me too.

Lacking a backup, you may have to redo some of the configuration. However, docker containers and plugins that were installed via CA Apps can be be reinstalled with with all previous settings intact via Previous Apps from the Apps tab. If you use the same USB flash drive, get the *.key file from the config folder and copy over to new config once you recreate the flash drive. Worse case scenario will allow you to register a new flash drive GUID (if you need a new flash drive) for your unRAID license without needing to purchase a new license.

The docker templates on flash are required for Previous Apps. Copy as much as you can of config folder. That one file that isn't copying so far I believe is for MyServers plugin. Probably it would be included anyway with a new install.

So your saying just copy over the Basic.key and it should be fine? as in all my shares/data on the drives would be good and not deleted? as for the apps/plugins all were from CA as far as i know, see picture for reference.

Do what @trurl mentioned and copy everything you can from the config folder before recreating flash drive. Flash drive corruption does not affect array disks and data. Shares are just top-level folders on disks and should still be intact unless your power outage somehow affected the array drives. This is why a UPS is highly recommended.

August 29, 20223 yr 22 minutes ago, Hobin said: Okay it seem to work, but now the issue is it cant seem to find the key? Your screenshot above shows both a trial key and a basic key. Did you use the same flash drive from when you purchased the basic key or a new flash drive? Is the basic.key file in the config folder on the flash drive from which you are currently booting?

Ahh so your saying only have one .key file in the config? not both which would make sense, i believe it has both in it just because thats what i copied over
August 29, 20223 yr Just now, Hobin said: i used a new one, same brand and everything License is tied to the GUID of the flash drive. Since you used a new flash drive, you will need to register the license with the GUID of the new flash drive. Click on the flash drive link from the main page and then the registration key manager link.
August 29, 20223 yr Solution Just now, Hobin said: Ahh so your saying only have one .key file in the config? I just wanted to confirm that the basic.key file existed on new flash drive. If not, it was probably trying to use the expired trial key. You need to register the GUID of the new flash drive.
