Ellis34771 Posted October 24, 2023 Share Posted October 24, 2023 I want to replace an 8TB parity disk with a 10TB disk. (That's straightforward enough, remove / replace, let it rebuild) But: I want to re-use the 8TB old parity disk to replace a 4TB drive. When I plug it in, will un-raid re-recognize it as the old parity disk? Will it (hopefully) prompt me to re-format it and re-use it? Or ... is there another procedure I'm missing here. Thanks in advance. Quote Link to comment

After the 10TB parity sync is complete, simply assign the old 8TB parity to a data slot. Unraid will prompt you to clear and format it. Quote Link to comment

Do NOT format if asked, rebuild should just be straight forward. Clearing and formatting is only applicable to adding a NEW data slot, not replacing an existing one. The format will be recreated as part of the rebuild process. Quote Link to comment

Hmm, I read the original question as wanting to add the old parity as an additional data disk. My mistake. If replacing an existing data disk, then yes, don't format. Quote Link to comment
