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.

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.

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.

Correct me if I'm wrong but I believe you would have to replace BOTH parity drives.

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
