Musical Hard Drives?!?!

[nokdim]

I have a setup as follows:

 

5X2T Data Drives

1X2T Parity Drive

1XSSD Cache Drive

 

Data Disk #5 died and its running on parity so all is well as far as data access.

Went to store and got 1X4T drive cause 4T is same price now as 2T was when I first built this.

 

I want to make the 4T drive my new parity so that as additional 2T drives fail I can swap them with 4T.

 

Not sure the best approach but I stopped the array and added a second parity and am rebuilding the parity and my plan is once parity is rebuilt I was going to down the array and remove the 2T parity drive and try to assign it as data drive #5.

 

Is this going to work? is there a better way to do this? is this even possible?

 

I found this link below but since I had a failed data drive I didn't want to chance anything so took my approach

Thanks again!

It will work but the parity swap would be the recommended procedure for this.

 

When you remove the 2TB parity you'll need to first start the array with it unassigned so unRAID can "forget it" before you can use it as a disk replacement.

perfect! Sorry I was scared with a dead data drive and didn't want to mess with the parity drive while the data drive was dead but thanks for confirming.

I will make sure to start the array without the 2T parity so it forgets about it and stop it again and add it back as a data drive.

process worked as planned, system is back and happy with a 4T parity so going forward any failed data drives should be much easier to swap.
