bobalot Posted October 30, 2022 Share Posted October 30, 2022 Background: I have an array of: One 8TB parity drives Three 4TB hard drives I was attempting swap out a single 4TB hard (virtually empty) with a 8TB hard drive I obtained. I shutdown the server. I removed one 4TB and connected the 8TB one. There seemed to be issues with the 8TB hard drive. So I shutdown the server and put the 4TB back in (and took the 8TB out). Current problem Unraid won't allow me to stop the array to re-add the 4TB drive. It is in stopping mode forever. Diagnostics attached and screenshot attached. Is there a way to resolve this? Thanks in advance. tower-diagnostics-20221030-2125.zip Quote Link to comment

I disabled it and also turned off all dockers and it has allowed me to stop the array! Cheers. Only problem is that it wont allow to swap out the 8TB for the 4TB even though they were both empty (and there were problems with the 8TB). It says: Quote The replacement disk must be as big or bigger than the original Is there a way to get around this? Edited October 30, 2022 by bobalot Quote Link to comment

Managed to avoid this issue, I got a replacement 8TB drive and it works ok. It is rebuilding right now. Thanks for all your help. Edited November 3, 2022 by bobalot Quote Link to comment
