Pool Issues - Incorrectly Formatted Disk

TrueNAS General
1

I just purchased a new Dell R760 for storage.

The storage controller is in IT mode so that all of the storage drives are passed through directly to the OS.

When trying to create a storage pool, I receive the following message:

Error: [EFAULT] Disk: ‘sdd’ is incorrectly formatted with Data Integrity Feature (DIF).

All of the drives are showing this message. These are brand new Dell-branded drives.

Dell branded drives use non standard sector sizes like 520 for example so you will need to format them to 512 or 4k. You can confirm this with:

sg_readcap /dev/sdd and take note of the ‘Logical block length’

You can then format them with the below command:

sg_format --format --ffmt=1 --size=4096 /dev/sdd

The --ffmt=1 option speeds up the process.
