Thanks for the info. And thanks for your help with getting me up and running again. Unraid is awesome 😎

I got to impatient and started the array after running those commands! It's all working fine, Unraid is not informing me that the drives need formatting and my Docker apps are available again! I'd be interested to learn why this command; btrfs-select-super -s 1 /dev/nvme0n1p1 resolved the issue. Can you tell me what this command did to resolve the issue please. I really appreciate you help, saved me hours of reconfiguring my Docker apps! 😁

Heres the output. root@IrisOne:~# btrfs-select-super -s 1 /dev/nvme0n1p1 using SB copy 1, bytenr 67108864 root@IrisOne:~# btrfs fi show Label: none uuid: bea95f7c-fcd4-4b53-8436-c4774afc1081 Total devices 3 FS bytes used 61.36GiB devid 1 size 119.24GiB used 33.03GiB path /dev/sde1 devid 2 size 119.24GiB used 33.03GiB path /dev/sdg1 devid 3 size 931.51GiB used 4.00GiB path /dev/nvme0n1p1

Hopefully I have attched the correct information 😁 irisone-diagnostics-20230205-2221.zip

Hi, I have been trying out Unraid for the last couple of weeks. It's great, wish I had discovered it sooner! I was running Unraid on a test system, a HP Gen 8 Microserver. Worked great, butI decided I needed more CPU power and RAM so moved to a new system. 7700K with 32GB RAM. All went well until I tried to add an NVME drive to my cache pool. I added an 1TB nvme to my existting Cache and now Unraid is saying "Unmountable: No file system" for the drives that were already in the Cache pool. I stopped the Array and and removed the 1TB nvme, but the "Unmountable: No file system" issue is still apperent. The cache pool had two 128GB SSD drives before adding the nvme drive. All of my Docker instances are now missing. Appdata folder is empty. What can I do to bring the Cache back online without losing all of the Docker images I have spent hours setting up? Thanks 😎
