Why I can't add the disk with the xfs file system to the disk array.

[gplayer]

I have 3 disks, the capacities are 4t, 8t, 16t respectively, and the file systems are all xfs. 4t and 8t can be added to the unraid disk array. But 16t cannot . I can manually mount it on the command line .The 16t hard drive is full of data, so I want to join the unraid disk array without reformatting.

Below is the display result after fdisk -l:

Disk /dev/sdc: 14.55 TiB, 16000900661248 bytes, 31251759104 sectors

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes

That's not possible, Unraid requires a specific partition layout and signature, you can mount the disk with UD plugin and copy the data to another disk(s) on the array.
