August 29, 20232 yr It's the first time I had to replace a faulty drive. I replaced it for a larger disk (6To to 8To) and I also improved my setup by adding a SSD for cache but when the rebuild finished, the new drive is still unmountable and the data that was on the faulty drive missing. Is there still a possibility to retrieve it somehow? At the very least I have to understand what went wrong in order to avoid this in the future. I schedule a parity check every week and I let the faulty drive in, is it possible that the parity check corrected the parity by substracting the data that it was unable to read because of the faulty drive ? Here below the situation at this moment.
August 29, 20232 yr Community Expert Was the drive showing as unmountable before the rebuild started? Asking because a rebuild does not clear an unmountable state. Handling of unmountable drives is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the GUI or the DOCS link at the top of each forum page.
August 30, 20232 yr Author Here the diagnostic. The drive was shown unmountable before the rebuild began. I was tempted to format it but the message was pretty clear that format is not part of the process of rebuild so I assumed the rebuild process would create a FS. library-diagnostics-20230830-2018.zip
August 30, 20232 yr Community Expert First upgrade your Unraid release, there's a bug with the one you are running, after upgrading unassign disk7 and post new diags to see if there are also other issues.
September 6, 20232 yr Author Ok, I've upgraded unraid, unassign disk7 and rebooted. Here the logs. library-diagnostics-20230906-2252.zip
September 9, 20232 yr Author Unraid refuse to start without the disk 7 assigned even in maintenance mode, the button is greyed so I started in maintenance mode with it. library-diagnostics-20230909-1115.zip

September 10, 20232 yr Author I should I've seen this. It allowed me to format my new cache drive. library-diagnostics-20230910-1336.zip
September 10, 20232 yr Community Expert Solution Emulated disk7 is mounting, you can now reassign the disk to rebuild.
