Cant add a disk to my array


Go to solution Solved by JorgeB,

I had an array of six 8TB drives with two of them parity drives.  I needed some more drives for another project so i got three 16 TB drives and planned on swapping them for the 8 TB drives.   I swapped out the parity drive and rebuilt the array then did the same for Parity 2 with no issues. 

Now when i try and add(or replace) the last 16 TB drive to the array it says i cant start the array because "Disk in parity slot is not biggest."

All three of these 16 TB drives are the same model and the exact same size.  I tried to pre-clear the drive before adding and that didn't help either.

I have attach the diagnostics zip.  Any help would be greatly appreciated.

Yup you are correct.  I did use the parity drive before i added it and did not pre-clear it.

parity (sdj)

root@NAS:~# fdisk -l /dev/sdj
Disk /dev/sdj: 14.55 TiB, 16000900661248 bytes, 31251759104 sectors

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: gpt

Parity 2 (sdk)

root@NAS:~# fdisk -l /dev/sdk
Disk /dev/sdk: 14.55 TiB, 16000900661248 bytes, 31251759104 sectors

Disklabel type: gpt

/dev/sdk1     64 31251759070 31251759007 14.6T Linux filesystem

drive I'm trying to add (sdd)

root@NAS:~# fdisk -l /dev/sdd
Disk /dev/sdd: 14.55 TiB, 16000900661248 bytes, 31251759104 sectors
Disk model: ST16000NE000-2RW
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device     Boot Start        End    Sectors Size Id Type
/dev/sdd1           1 4294967295 4294967295   2T  0 Empty

Partition 1 does not start on physical sector boundary.

 

So it looks like I need to take this new drive and make it the Parity drive.  correct?
