Here's my stupid question of the day. I have a new Fractal R3 to replace my NAS's Antec 300. I've got Ubuntu Server and MDADM set up with a 5x 1TB RAID6 configuration. Here's the specific details about my MDADM configuration. Code: > cat /proc/mdstat Personalities : [raid6] [raid5] [raid4] [linear] [multipath] [raid0] [raid1] [raid10] md0 : active raid6 sdd1 sde1 sdf1 sdb1 sdc1 2930280960 blocks super 1.2 level 6, 128k chunk, algorithm 2 [5/5] [UUUUU] Code: > cat /etc/mdadm/mdadm.conf ARRAY /dev/md0 UUID=9de23957:7afe0da8:489f8918:50727432 PROGRAM /home/raid/raid-email.py Since I have everything being identified by UUID, does hard drive order even matter? I don't want to screw up the array just because I cross a SATA cable or two accidentally. That being said the only data on the array is backups for other PCs anyway. Easily to recreate if there's a problem but it would be a pain. Still assume I need to keep the boot HDD on the same SATA port as well? Or do I just need to make sure BIOS are set to boot to the right hard drive?
