probefahrer Posted July 25 Share Posted July 25 Hi there and sorry to bother here. I used the search but I am still confused, since I mostly found information on how to build a new USB-stick and reregister it - but not what to do next. So I started my unraid server in december as an experiment and replacement for my 10 years old synology. Unraid convinced me immediately and it ran very well until powered it down 2 days ago and now it does not seem to boot anymore. When I put the stick in one of my other Macs it is not recognized. Problem is: I _thought_ that I had a Backup on my Laptop and I _thought_ I activated the Unraid Connect Flash Backup. Turns out: It seems like I managed to screw them up both So my question is: 1. Can I build a new USB-Stick, boot the Unraid with it, mount the existing array full of data again and reregister the stick then? There is also a Cache-SSD in there. So can I get the fresh USB Stick work with the existing config on the system, since the old USB does not seem to work anymore? 2. Do I have to rebuild the whole system but be at least able to use the Data on the Parity- and the Data-Disk? 3. Am I screwed and the whole data is gone? I really appreciate your help.

trurl Posted July 25 Share Posted July 25 Without flash or flash backup you have no existing configuration. But the data on your existing disks should be OK. https://docs.unraid.net/unraid-os/manual/changing-the-flash-device/#what-to-do-if-you-have-no-backup-and-do-not-know-your-disk-assignments Quote Link to comment
probefahrer Posted July 25 Author Share Posted July 25 Thanks! I will try that tomorrow. The Unraid-box is not reachable in the network when i boot with the fresh stick. So I have to look into that tomorrow with fresh eyes. Quote Link to comment
