superloopy1 Posted July 30, 2023 Share Posted July 30, 2023 (edited) I have just increased one of my arrays 12TB drives with a larger drive. I now want to reuse this 12TB drive in my backup system and obviously it still has all of the 'old' outgoing data on it which is no longer needed. The drive is still in unraid format so i'm wondering do i just repeat the process i used to switch in a larger drive and replace any drive on my backup system with this 12TB WITHOUT the need to reformat or delete any of the 12TB contents. Will Unraid just rebuild the image of the existing backup drive onto my 12TB drive as if it didnt already have data on it? It would save a lot of time and effort if thats how it works. I'm concerned that it may just 'import' whats on the old drive at the expense of whats currently known to the backup system. That would be a disaster! Cheers!

Veah Posted July 30, 2023 Share Posted July 30, 2023 Just add the drive. Your other unRAID will format it and enable it for you with no difference from a new drive. 1 Quote Link to comment

But will it rebuild it as per the drive it is replacing and NOT add it as a new empty drive, that's my question. Quote Link to comment
Veah Posted July 31, 2023 Share Posted July 31, 2023 (edited) Yes. The drive will not retain the information coming from it's previous home. All that goes away. unRAID will treat it like a new empty drive and make it ready for it's new home. It's previous life will be lost. Edit add: it will populate as if it is the drive you are replacing. Edited July 31, 2023 by Veah 1 Quote Link to comment
JorgeB Posted July 31, 2023 Share Posted July 31, 2023 If you are adding a drive (not replacing onw) it will be cleared first, then you format it. 1 Quote Link to comment

If it replaces a drive then it will be rebuilt with that drives contents. Its current contents are irrelevant as the rebuild process overwrites every sector in the drive. If it is added as a new drive then any existing contents will first be cleared so again any existing content is irrelevant. 1 Quote Link to comment
