Disk in parity slot is not biggest.

[leonardootto]

Hello,

I have a setup with a 14TB parity drive and a 6TB data drive in my Unraid system.

I recently purchased a new 14TB drive and attempted to add it to my array as a data drive. However, when I try to start the array, it fails with the error: "Disk in parity slot is not biggest."

Here are the details of the two drives:

 

root@enterprise:~# fdisk -l /dev/sdl
Disk /dev/sdl: 12.73 TiB, 14000519643136 bytes, 27344764928 sectors
Disk model: ST14000NM001G-2K
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
Disk identifier: xxxxxxxxxxxxxxxxxxxxxxxx

Device     Start         End     Sectors  Size Type
/dev/sdl1     64 27344764894 27344764831 12.7T Linux filesystem
root@enterprise:~# fdisk -l /dev/sdg
Disk /dev/sdg: 12.73 TiB, 14000519643136 bytes, 27344764928 sectors
Disk model: ST14000NM001G-2K
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
Disk identifier: xxxxxxxxxxxxxxxxxxx

Device     Start         End     Sectors  Size Type
/dev/sdg1     64 27344764894 27344764831 12.7T Linux filesystem
root@enterprise:~# 

Both drives are the same size and start at the same sector.

Can you help me integrate this new 14TB drive into my array, even if it means I need to shrink it slightly?

Thanks,

Please post the diagnostics.

I don't see why this is happening, most likely not going to change anything, but update to v6.12.6 and post new diags as well a screenshot showing the error.

Follow the infos:

Your parity2 disk is only 6TB so cannot add array drives larger than that until that drive has been upgraded to a larger size.  You can never add array drives that are larger than the smallest parity drive..

Humm. I think it can not be larger that the larger one. Get it.
Thanks

Oh man, can't believe I missed that, I blame it on the Christmas eggnog
