shaunmccloud Posted March 16 Share Posted March 16 (edited) I had an 8TB data drive due today. Ordered a 14TB replacement, then realized I only have 10TB parity drives. Can I drop the 14TB drive in place of one of my parity drives and rotate that parity drive to a data drive without losing any data since I have two parity drives?

Are you talking about adding the old parity drive as an additional drive or are you replacing an existing data drive. Quote Link to comment

Replacing an existing data drive that died. But I can't use the 14TB drive I ordered as a data drive with 10TB parity drives. I have two 10TB parity drives.

Solution itimpi Posted March 16 Solution Share Posted March 16 If you are replacing a data drive then you can use the Parity Swap process to update a parity drive to 14TB and use the old 10TB parity drive to replace the data drive. Quote Link to comment
Venares Posted March 18 Share Posted March 18 Correct me if I'm wrong but I believe you would have to replace BOTH parity drives. Quote Link to comment

Only when they would want a data drive larger than 10TB. The parity drives in Unraid are totally independent, the only rule is that they must be equal or larger than any single data drive. How the OP explained the situation was Parity1 - 10TB Parity2 - 10TB Failed data - 8TB Replacing either P1 or P2 with the 14TB and using the 10TB as the replacement for the failed data drive is perfectly fine. P - 14TB P - 10TB D - 10TB 1 Quote Link to comment
