February 6, 20251 yr I have an issue with my unraid. One of my discs got disconnected. Now it is shown as unassigned: But it is still available: If I reassign it, I get a message, that all data will be removed / overwritten once I start the array. So I didn't start the array. How can I fix that the right way?
February 6, 20251 yr Community Expert Disk was disabled, so it needs to be rebuilt, first start the array with disk1 still unassigned and post the diagnostics.
February 6, 20251 yr Author Thank you for quick response! Please find attached the diagnostics. unraid-diagnostics-20250206-1133.zip
February 6, 20251 yr Community Expert Solution Emulated disk1 is mounting, assuming contents look correct, you can rebuild on top: https://docs.unraid.net/unraid-os/manual/storage-management#rebuilding-a-drive-onto-itself P.S. note that SSDs in the array cannot be trimmed.

February 6, 20251 yr Community Expert You can browse the emulated disk contests, but since it's btrfs, and as long as it mounts, it should be all fine.
February 6, 20251 yr Author I followed the instructions. I reassigned the drive as said in step 6. But now it is saying: All existing data on this device will be OVERWRITTEN when array is Started And next to the Start-Button it says: Start will start Parity-Sync and/or Data-Rebuild. Did I follow the right steps and can proceed with the start of the array?
