Worth considering, at least. Might even work well in your planned > raid-6 config. > Yea, I thought about that too. So you're suggesting a RAID1 consisting of (2) RAID6 arrays. Will mdadm do that? Also in other news.... (maybe someone from this list can help since they've run into it before) The motherboard of the computer has its own SATA controller as usual... as well as this Avago SAS controller. When CentOS 7 boots up, it enumerates the external SAS drives starting at /dev/sda instead of the motherboard's drives. The OCD in me wants the MB's SATA drives as /dev/sda-sdd. Where does one even control that enumeration order? udev? Eeks. (I'm not finding a query that google makes sense out of to give me a decent set of suggested links.) -Ben -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
