SOLVED Can I move a drive SATA position ?

[iXô]

Hello,

I would like to move 2 drives of a raidZ2 array from the motherboard sata connectors to a LSI board.

When I have bought the board I had only 1 cable, which makes me unable to use the full potential of the board, now that I need the motherboard connectors, I will by the cable and want to move the drive to the board.


Is it possible ? does zfs care of the physical position, or can it found where are the discs during the import boot operation ?


Thanks.

Thanks.

Whether your system cares about drives on motherboard vs drives on LSI card depends on the model / firmware of the HBA / raid card. Without more info the answer is 'possibly'.

As long as the LSI card is acting as a pure HBA, and presents the drives directly to the OS, it won't make a difference.

As long as the LSI card is in IT mode, it just functions as SAS/SATA ports and you can shuffle SATA drives around between any supported SAS/SATA port on a FreeNAS system with impunity.

Great ! I didn't take the fact that the LSI board wasn't in IT mode, as I think this if mandatory for ZFS / Freenas and LSI.

In fact, the question could have been asked without speaking of the LSI card.

So, you all confirmed that the physical position of a hard drive is not important for ZFS.

Thanks for all.

It's not even important to FreeBSD in general if you take advantage of GPT and labels, which is a Really Good Thing to do.
