September 15, 20241 yr Hey Unraid Community. My Unraid auto-shutdown when my UPS had about 10 minutes of battery left during a power outage, as configured. However, when I powered it back on, the USB got corrupted and it wouldn't boot. I tried to do some data recovery on the USB, but at the end of the day I had an 8 month old back up of the Flash USB and just formatted the same USB key (another on order), got Unraid back on it, copied /config and booted back into Unraid. However, at least one of two cache (tier1-cache) did not come back up and gives the error: "Unmountable: Unsupported or no file system" The backup is several months old, Nov 2023 and I am unsure if potential changes between then and now is causing the problem with the caches. When the array is offline, I can see the two NVMEs, however the only option Unraid is currently giving me is to format. As these were front-end cache for AppData and Domains, I'd prefer not. Most of the data is backed up offline if I really need to recover. Here are some screenshots, home
September 16, 20241 yr Author Good Morning, here is the output from "zpool import". Looks like I have the pool name wrong. This is likely from the backup being older and missing the current configuration. What would you suggest is the corrective? (I will open a new thread on the UPS "graceful" auto-shutdown nuked my USB)

September 16, 20241 yr Community Expert Solution Try re-importing the pool and it should mount, stop the array, unassign both pool devices from the tier1 pool, start array, stop array, re-assign both devices and start array, the pool should import, if it doesn't post new diags.
September 16, 20241 yr Author Thank you @JorgeB That brought the pool back with data. Last question. VMs came online but Docker says there are no containers. Is this just a matter of me recreating each container and pointing it back to its AppData folder?
September 17, 20241 yr Community Expert As long as you have the appdata share and the user-template folder on the flash drive, you can just recreate the image and add them from previous apps: https://docs.unraid.net/unraid-os/manual/docker-management/#re-create-the-docker-image-file Then: https://docs.unraid.net/unraid-os/manual/docker-management/#re-installing-docker-applications Also see below if you have any custom docker networks: https://docs.unraid.net/unraid-os/manual/docker-management/#docker-custom-networks
