jawolf Posted June 11, 2020 Share Posted June 11, 2020 During a data rebuild to upgrade a drive, another drive started to fail (5000+ reallocated sectors). I have stopped the rebuild. I made no changes to the data on the array after starting the rebuild and I have the drive I was upgrading intact as it was when I took it out of the array. Is it possible for me to put the old drive back in the array and then replace the failing drive instead? If so how would I go about this? I have a backup of the array configuration from before I added the new drive. Can I do the following: -- Shutdown the array -- Copy the backup configuration to the USB drive -- Put the old drive back -- Restart the array -- Confirm everything looks OK -- Replace the failing drive and rebuild Would this work? Would it preserve all of my data? Is there a better way? I would appreciate any assistance anyone can provide. Thanks! Jeff Quote Link to comment

Should work fine, but note that unless the rebuild was done in maintenance mode parity will always be a little out of sync due to mounting the filesystems, though this is usually not a big deal, if for some reason your backup doesn't work you can also try the invalid slot command.

jawolf Posted June 12, 2020 Author Share Posted June 12, 2020 The backup worked fine. The bad drive is almost finished rebuilding. Thanks for your help! Quote Link to comment
