Moving system to a new chassis?

I’m moving my TrueNAS CORE system to a new chassis (see below). When I pull the 12 drives (two vdevs) out of my original system and move them to this new chassis, will ZFS keep track of the drives or will I need to plug them into the same SATA ports on the MoBo?

I’m thinking I only need to pay attention to my mirrored boot drives.

Thnx,

Supermicro CSE-836BE1C-R1K03B SAS3 12Gb/s 16x 3.5" 3U Rackmount Server Chassis
Key Features
3U chassis - supports for maximum motherboard sizes: 13.68" x 13" E-ATX and ATX
16 x 3.5" hot-swap SAS/SATA drive bay with SES2, optional 2 x 2.5" hot-swap drive bay
16-port 3U SAS3 12Gbps single-expander backplane, support up to 16x 3.5-inch SAS3/SATA3 HDD/SSD
1U 800/1000W Redundant Titanium Single Output Power Supply W/PMbus

The SATA port doesn’t matter when it comes to TrueNAS determining what is what. It will figure it out either way.

Connect your M1015 to your backplane.

It’s unnecessary to mirror your boot-pool, but it doesn’t hurt you in this scenario either, so just move your gear over to the new chassis and verify that everything is plugged fully.

Does anyone have any recommendations on a RAID controller or Host Bus Adapter to connect my SuperMicro X10SLL-F motherboard to the backplane of the SuperMicro CSE-836BE1C-R1K03B SAS3 chassis?

I would get something like the 930X-8i or similar. (3008-based).
In a pinch - a 9200-one.

I would buy it from ebay, from a server surplus operation (ideally something local).
Not Chinese direct import.

I’ve ordered a LSI 9300-8i.

ChatGPT agrees with you:
Things to Consider for the Migration:

1. Compatibility with Your IBM M1015 (SAS2 6Gbps)

  • The new CSE-836BE1C-R1K03B chassis has a SAS3 (12Gbps) backplane, but your IBM M1015 (SAS2, 6Gbps) controller will still work fine.
  • However, if you want to fully utilize 12Gbps SAS speeds in the future, you may want to upgrade to a Broadcom/LSI 9300-8i or higher (like a 9305 or 9400 series).

ChatGPT also offhandedly suggested: :slight_smile: Which I thought was interesting. lol
CPU Upgrade (If More Processing Power is Needed)

  • The Xeon E3-1220 v3 is fine for most NAS tasks, but if you’re doing Plex transcoding, some VM work, or heavier workloads, a Xeon E3-1245 v3 or E3-1275 v3 (which support hyperthreading) would be a solid drop-in upgrade.

Is your plan to fully replace the M1015 with the new HBA? Or will you use the M1015 for something else in the system?

Be sure to check the firmware version when you get the new card, even if the seller claims that it comes preflashed, verify using something like: sudo sas3flash -list

Don’t forget you also need cables to connect the HBA to the backplane.

I’ll be replacing the M1015 with the LSI 9300-8i.

I’ll confirm the firmware of the 9300. Could I do this by first installing my mirrored boot drives, which will be on my MoBo SATA ports, and before installing my pool drives run the above command? After confirming the 9300 is in IT mode then install the 12 pool drives. After which everything should boot up perfectly. :slight_smile:

I have ordered a couple SFF-8643 to SFF-8643 Cables.

Sure, no problem.

Those look good.
I think you can connect both cables coming from the HBA to PRI-J1 and PRI-J2 respectively, although I am not sure on that. If you get duplicated drives appearing, you’ll need to go down to a single cable.
