* Does order/ sequence of SATA drives matter? @ 2014-11-17 10:13 forumscollective 2014-11-17 11:31 ` Robin Hill 0 siblings, 1 reply; 2+ messages in thread From: forumscollective @ 2014-11-17 10:13 UTC (permalink / raw) To: linux-raid The motherboard on which I was running a mdadm 8TB array comprised of 5 x 2TB drives has packed up so the array needs to be moved to a new motherboard. Is the sequence of connectivity to motherboard SATA ports important or does mdadm identify each drive and automagically know its sequence in the array?

If you're using a RAID1 array for the boot drive, you'll need to make sure that the correct disk is set in the BIOS to boot from though (or that the boot block was installed to all array members).
