Drazzilb Posted January 24, 2020 Share Posted January 24, 2020 Well it has finally happened. After 7 years of service one of my WD 2tb green data drives has finally bitten the dust. I’m currently a little strapped for cash and wasn’t planning on any upgrades any time soon however I do want to get this drive replaced. In my array I have two 4 tb WD red drives as my parity so what I’m looking to do and to see how this is done is using the second parity drive as the replacement for the disabled drive. If this is possible how do I go about doing this with out any data loss. Quote Link to comment
trurl Posted January 24, 2020 Share Posted January 24, 2020 It should be possible to just assign existing parity2 to the data slot you want to replace and let it rebuild, but I'm not sure if Unraid will allow that without New Config. And if New Config is necessary the invalidslot command would also be required. So I will punt to @johnnie.black on this one. While waiting, go to Tools - Diagnostics and attach the complete diagnostics zip file to your NEXT post. Quote Link to comment

If this is possible how do I go about doing this with out any data loss. Removing a parity disk is covered here in the online documentation. Since you started with 2 parity disks you will still be protected against a single drive failure (which is the current state of your data disks). You can now use the 4TB disk you just removed and follow the Normal disk replacement process. Quote Link to comment
JorgeB Posted January 24, 2020 Share Posted January 24, 2020 Yeah, you just need to make Unraid "forget" that parity by unassigning it and starting the array, then are free to use it as a replacement disk. 1 Quote Link to comment
Drazzilb Posted January 24, 2020 Author Share Posted January 24, 2020 Thanks guys. I thought it was as simple as that. Hi just had to ask. I like most of us am paranoid about losing data. Quote Link to comment
