maverhick Posted April 2 Share Posted April 2 (edited) In my machine, 2 of my 4TB drives decided to play truant together and are now showing up as not installed. I also found a 4TB listed under Unassigned devices. There is no 2TB unassigned device that I am aware of or is connected to the machine. I need help with next steps. How do I diagnose these 2 drives and what next steps could I take to get them to be detected back into the array? Else is my option finding a 8TB drive and plugging it in and rebuilding the array. Looking to hear suggestions on getting this out of the way. I am so thankful that I have a 2 drive parity, else I would have pulled my hair out diagnostics-20240403-0022.zip diagnostics-20240403-2125.zip Edited April 3 by maverhick Adding diags Quote Link to comment
JorgeB Posted April 3 Share Posted April 3 Is the unassigned 4TB drive one of the missing drives? As for the other missing one, check all cables, or swap with a known good one. Quote Link to comment

maverhick Posted April 3 Author Share Posted April 3 I resettled the cables and now both drives are showing up as unassigned, both seem to have smart errors as well. Now the Array error is " Array has 1 SMART error." which is showing up on the parity drive Quote Link to comment

Solution JorgeB Posted April 3 Solution Share Posted April 3 Both disks look mostly OK, most likely it was a power connection issue, if the emulated disks are still mounting and contents look correct, you can rebuild on top: https://docs.unraid.net/unraid-os/manual/storage-management#rebuilding-a-drive-onto-itself Quote Link to comment

The array is back on and chugging as usual. My heartfelt appreciation for the work you do 1 Quote Link to comment
