HI. Ran across an issue with Shrinking my array.
History ..... I had a server with 16+ disks. The drives were smaller/older - around the 4-5tb era. About a year ago I decided to migrate to larger drives, so I can reduce the number of overall drives. I swapped in 2 new 16TB parity drives, and replaced several other drives over the last year. I followed the documentation, and all of that has gone well. Zero issues.
I decided to shrik my array by 3 drives (4tb, 4tb, 5tb). This is the first time I tried that. I followed the online documentation:
https://docs.unraid.net/legacy/FAQ/shrink-array/#the-remove-drives-then-rebuild-parity-method
Everything seemed to go well. Parity rebuilt. Data seems in tact. However, I now have 3 empty slots in my array, and the array doesn't auto start after reboot because of it.
I read over the documentation again, and there doesn't seem to be a step to 'move the drives up' to fill those vacant slots. But that seems to be what I need to do. Maybe by way of a New Config. And possibly selecting that the Parity is valid, so it doesn't have to do it again. But I defintely don't want to mess up any data, so I'm asking experineced experts how to proceed.
Thank you.
