USB failure after power outage. No backup files!

[nakamurak002]

Hi, we recently had a power outage and now UNRAID wont boot.  I put the Unraid USB on me newly built desktop and it cant be seen and is probably dead.  My problem is I have NO backup files for the USB...none.  I did have a file on my old windows PC, but I don't have it and didn't get a chance to back it up on my new machine ( which is only a couple weeks old) or make another USB.  Where do I go from here?  All the other posts seem to still have access to UNRAID and can backup or fix it.  Mine wont even boot.  I have NO files or data on which drives (8 of them) are parity and which are shares.  I do NOT have access to be able to recreate the boot USB files onto another USB.

Did you have status emails set up? Do you have any diagnostics from when the server was running?

it is possible to get your data dries back online using the technique described here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI.   Your shares will get reinstated but only with default settings.    Docker containers and VMs will need setting up again.

(TO Jonathan M) No, I'm pretty new to UNRAID.  I just rebooted the server and it does boot to the UNRAID menu, so I guess I still have something on the USB.   I just selected "UNRAID OS" and it appears to be stuck on "bzroot" for the last few minutes.

 

(To itimpi) I'll try and read up and see if that helps.  thank you

sometimes downloading the zip file for the release and extracting all the bz* type files overwriting the ones on the flash drive can help if the system is having trouble reading these standard system files off the flash drive.

I just tried to reboot on "UNRAID OS GUI safe mode (no plugins) and its stuck on "bzimage" and never made it to "bzroot"  i havent tried to extract and overwrite yet.  Does it matter what release I download as I don't know what release I have on the USB?

[nakamurak002]

I just tried to reboot on "UNRAID OS  safe mode (no plugins, no GUI) and its stuck on "bzroot" again, but "bzimage" read as OK.

Thanks again itimpi.  I replaced the bz files and got it started in safe mode.  Running a parity check right now.  What do you recommend I do first once that is done to safeguard against future problems?

Always keep a current backup of your flash drive. Any change you make in the webUI is saved on flash so if you want those changes to be included in the backup you need to get a new backup.

 

You can download a zipped copy of flash from Main - Boot Device - Flash - Flash Backup.
