Thanks for this. So basically, the naming of the device is only
important at the time of creating the array (as that defines the
layout). As soon as I create the array, mdadm puts it's own metadata on
the drive so it can identify them afterwards? That sounds very good indeed.
Now, onto the topic of PCIe adapter. I was looking at this:
http://www.cclonline.com/product/42541/PEXSAT32/IDE-SATA-SCSI-Cards/StarTech-2-Port-SATA-6-Gbps-PCI-Express-SATA-Controller-Card/CNT1075/
Is that a bad model? Seems a little on the cheap side? Can anyone
suggest a good model?
Many Thanks for all the help
