fishpen0 Posted October 3, 2022 Share Posted October 3, 2022 (edited) Had a disk (disk 6) go bad, ordered a replacement. Turned off the array. I unseated the wrong disk (disk 5) in the array while looking for the bad disk and reseated it. Found the bad disk, then popped in the replacement, then selected the new disk from the dropdown and then clicked start. Then something went horribly wrong and disk 5 failed to mount. Now I have a disk on rebuild and a disk on failed to mount. I reseated the now failed disk 5 and now I need to figure out how to get it back into the array so I can rebuild 6. I only have a single parity disk. I cancelled the rebuild and stopped the array because I'm not sure how to continue. Most of the advice here for keeping an existing disk relies on the rest of the disks still being workable to do an in-place rebuild of the one you are keeping, but I can't do that for this disk. box-diagnostics-20221003-0902.zip Edited October 3, 2022 by fishpen0 Quote Link to comment
JorgeB Posted October 3, 2022 Share Posted October 3, 2022 This will only work if parity is still valid: -Tools -> New Config -> Retain current configuration: All -> Apply -Check all assignments and assign any missing disk(s) if needed -IMPORTANT - Check both "parity is already valid" and "maintenance mode" and start the array (note that the GUI will still show that data on parity disk(s) will be overwritten, this is normal as it doesn't account for the checkbox, but it won't be as long as it's checked) -Stop array -Unassign disk6 -Start array (in normal mode now), ideally the emulated disk6 will now mount and contents look correct, if it doesn't you should run a filesystem check on the emulated disk and/or post new diags. -If the emulated disk mounts and contents look correct stop the array -Re-assign disk6 and start array to begin.

fishpen0 Posted October 4, 2022 Author Share Posted October 4, 2022 That seems to have done the trick. I'll know for sure in 3 days when the rebuild is done 😬 Thanks! Quote Link to comment
JorgeB Posted October 4, 2022 Share Posted October 4, 2022 I assume the emulated disk mounted? Quote Link to comment
