March 27, 20251 yr Quick update: I have now completed extended SMART tests on all remaining drives, and they all passed without errors. No signs of damage from the earlier power issue, so that is a relief. Thanks again for the guidance so far! Still waiting on the Clone - will probably get it next week sometime.
April 4, 20251 yr @trurl, @JorgeB, @itimpi I did everything up to: "Unassign the disk you want to rebuild" And now I want to start the array up again in Normal mode. But I cant click the "Start" button. I guess I have to click this checkbox "Start will disable the missing disk and then bring the array on-line. Install a replacement disk as soon as possible. [ ] Yes, I want to do this" ...right? Just want to make sure. Hope I did not mess this up already 😓 Edited April 5, 20251 yr by TreksterDK Spelling errors
April 4, 20251 yr Community Expert Missing/emulated disk6 is mounted and shows 68% full! No I/O errors in syslog (yet). Should be good to rebuild. Stop the array, reassign new disk, start the array to begin rebuild.
April 4, 20251 yr Data-Rebuild is running! 🤞 Will keep you posted. Thanks so much!! - for all the help - so far
April 5, 20251 yr Just wanted to say thanks - everything went smoothly! 👍 The missing disk has now been successfully rebuilt using the cloned drive (which is actually a borrowed disk): Duration: 14 hours, 45 minutes, 42 seconds Average speed: 150.6 MB/s Next step: I will remove the cloned disk and rebuild it onto a new 8TB drive. A huge thank you to everyone here for the invaluable help and guidance - it is truly appreciated! 🙏
April 5, 20251 yr Author Glad it worked out and thanks for posting the methodology! To tie things up for the original post, my drive wasn't able to be cloned and so I couldn't even begin the process to rebuild. So I simply started over with new drives.
