steelrat Posted January 1, 2023 Share Posted January 1, 2023 After downsizing my main Array and described by SpaceInvaderOne here (New Config > Preserve current assignments: all > then removing the device I didn't need anymore) I now get the error "unmountable: no pool uuid" on the cache drives. To be clear - I did not change the cache drives in that process. Any Ideas what happened here? The array is fine and all the data is there - it's just the cache that has issues... Best regards and a happy new year! primogenitus-diagnostics-20230101-1941.zip Quote Link to comment
steelrat Posted January 2, 2023 Author Share Posted January 2, 2023 Is there anything I can look for myself in the diagnostic logs? The 2 Cache Drives are supposed to be btrfs in raid 1 if that helps. Quote Link to comment

Solution JorgeB Posted January 2, 2023 Solution Share Posted January 2, 2023 The 500GB Samsung SSD was part of the pool in the past and is out of sync, disconnect that device and try again (or just wipe it). Quote Link to comment
steelrat Posted January 2, 2023 Author Share Posted January 2, 2023 Thank you - that solved the issue 👍 Wanted to add the Drive as a pass through for testing and had not thought about the fact, that it was an old cache disk... best regards 1 Quote Link to comment
