MSI B450 Pro & Ryzen 3 4100 does not recognize all HDDs in TrueNAS Scale OR BIOS

[Noah0302]

Hi guys,

 

Ive been running my TrueNAS for about 1 year without issue like this:
-NVMe Boot Drive

-4x 4TB HDD directly on the Mainboard

-4x 16TB HDD on a SATA III PCI-EXPRESS 2.0 x 1

This ran for a year without a single issue

 

However when I tried to add:

-4x 8TB HDD on a SATA III PCI-EXPRESS 2.0 x 1 (Exactly the same as the working 16TB drives)

only 2 of the new disks showed up, in TrueNAS or BIOS...

I tried swapping cables, that did not work.
Switching Ports did work somehow, then the other 2 Drives started showing up, but the original 2 went missing. This does not mean that the 2 Ports on the PCI Card are dead, because if I shut the System down, only connect 2 Drives to the "non working" Ports, they also show up.

 

Now my question is:
Is this a PCI Lane issue?
Does B450 simply not have enough lanes to drive 12 Disks + 1 NVMe?

I tried to google it, but answers like "The Mainboard only has 6 Ports, so only 6 are supported" does not help at all.

 

I hope someone here can help me with my issue...

 

Thank you for reading!

the pci-e sata controller is its own bus , the lanes don't matter

the actual pci-e sata controller probably just doesn;t support that many 8tb drives or the controller is just bad.

honestly if its a cheapo controller and not like a nice LSI or server grade component then them failing or working like crap is kinda common.

Yes, this might be the issue.

I bought the same that powered the 4x16TB Drives for the last year, so I thought it should be fine.

 

Ill try to upgrade to a quality HBA Controller with multiple SAS Ports and SAS to Sata Cables. That way I also only need to use one PCI Slot and can maybe fit a 10GB NIC into my System.

 

Thank you for the reply!

a nice SAS card will do you well. those cheapo sata cards might be the most broken pc parts that get sold regularly. they remind me of those regular pci usb 2.0 cards that were like 3$ shipped and never ever functioned back in the day. lol
