[Help] Disks with same serial in D8 Hybrid, firmware updated

[mmartin]

Hi folks,

I have one D8 Hybrid DAS updated with the latest firmware from viewtopic.php?t=6748 and I am using TrueNAS as the OS.

The issue with NVMe disks reporting the same serial seems to be fixed and I am able to use them in storage pools. However now I have kind of the same issue with the SATA drive. I have two WDC WD80EZAZ-11TDBA0 and two ST6000VN0033-2EE110 conected to the SATA slots and although all of them seem to be reporting different serial numbers with hdparm:

Code: Select all

root@terramaster[~]# hdparm -I /dev/sdd

/dev/sdd:

ATA device, with non-removable media
        Model Number:       WDC WD80EZAZ-11TDBA0
        Serial Number:      XXXXX7HD

        Transport:          Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0; Revision: ATA8-AST T13 Project D1697 Revision 0b 
        ...
        
root@terramaster[~]#  hdparm -I /dev/sde

/dev/sde:

        Model Number:       WDC WD80EZAZ-11TDBA0

        ...

root@terramaster[~]# hdparm -I /dev/sdg

/dev/sdg:

        Model Number:       ST6000VN0033-2EE110
        Serial Number:      XXXXXXJG
        Firmware Revision:  SC60
        Transport:          Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0
root@terramaster[~]# hdparm -I /dev/sdh

/dev/sdh:

ATA device, with non-removable media
        Model Number:       ST6000VN0033-2EE110
        Serial Number:      XXXXXXDA
        Firmware Revision:  SC60
        Transport:          Serial, ATA8-AST, SATA 1.0a, SATA II Extensions, SATA Rev 2.5, SATA Rev 2.6, SATA Rev 3.0

They cannot be added to a storage pool becasuse "Disks have duplicate serial numbers: 'A00022304202' (sdg, sdh)".

I was wondering where that A00022304202 serial number was coming from and it turns out that it comes from smartctl:

Code: Select all

root@terramaster[~]# smartctl -d scsi -x /dev/sdg

To get that output I needed to add -d scsi parameter because smartctl doesn't seem to recognize the USB bridge:

Code: Select all

root@terramaster[~]# smartctl -x /dev/sdg

/dev/sdg: Unknown USB bridge [0x1352:0xa006 (0x100)]
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

Indeed, the disks are not shown when running a scan:

/dev/nvme1 -d nvme # /dev/nvme1, NVMe device

Is this a known problem?, is there any way to fix or workaround it?

Thanks a lot for your help!

Thank you for your detailed feedback. Since SATA slots 1 and 2 are controlled by the same RAID chip, we recommend using the disks in slots 1 and 2 in a RAID configuration.
This may not support software RAID on TRUENAS, but the other three native SATA slots can support software RAID.

Thank you Phil for your reply and recommendation.

At the moment, I’m not using any supported RAID configurations (and, to be honest, I’d prefer not to). The D8 is set to the supported Single mode, and I can see four separate disks.

Shouldn’t each disk report its own serial number? This looks like a bug to me—am I mistaken?

Hello, due to the hardware design characteristics of the D8 Hybrid, the HDD1/2 ports are driven by the same controller chip. As a result, the hard drives installed in these two ports cannot display their individual serial numbers separately; only a unified HDD serial number will be shown. However, hard drives connected to the HDD3/4 ports can each display their own independent serial number normally.

Well that's not what I see in my system, disks in HDD3/4 ports also share serial number:

Early versions of the D8 Hybrid may have this issue. You can refer to this guide for firmware updates.

It is important to emphasize that during the update process, please make sure to remove all other hard drives and only keep the hard drive in the HDD3/4 port, otherwise, it may cause irreversible effects.
