Disk in parity slot is not biggest.

[Gobble45]

Hey guys,

 

so just last week i grabbed myself a few new drives for my array.

 

The existing array was made up of mostly 8TB Drives, with a few 3 & 4TB drives. I grabbed two 10TB drives with the intention of one being a second Parity drive, and the other being added to the main array.

Adding the second parity drive was fine. Time consuming, but fine. However adding the second 10TB drive to the main array keeps giving me the error "Disk in parity slot is not biggest." when i try starting the array.

I've tried preclearing the disk. I've tried investigating the actual size of disks using terminal commands etc., but i still cant determine why this is happening. I've attached diagnostics.

 

Any help is appreciated

No data disk can be larger than any parity disk. You will have to replace 8TB parity with the 10TB then you can reuse 8TB parity as a data disk.

hi, sorry my post may not be clear.

 

I've added one of my 10TB to the parity drives.. or am i misunderstanding, and i need both my parity drives to be the same size?

okay, so for clarfication, 

 

hypotherically, i could have a 10TB and 12TB parity disks. But so long as the main drives are not bigger than 10TB it will be fine.

in my case, i need to make BOTH my parity the 10TB drives?
