[CentOS] Controlling the order of /dev/sdX devices?

Nope, no LVM on the RIAD array.  It just needs to load right after the main LVM so that something removable doesn't wiggle its way in and mess up the device order.

Yes, the suggestion from Robert H looks promising - working on it now.  Did i say i hate udev?  I thought there was going to be a replacement for it at some point?

According to the OP's initial message, I think he's already doing this:

>> SATA system HDD /dev/VolGroup00/LogVol00 /
>> RAID array              LABEL=STORE      /store         ## mounts ==
>> /dev/sdb1

But I could be wrong.

The issue seemed to be that the udev rule prevented the detection of the LVM on that RAID completely when it came up as /dev/sdd.

The other udev rule in-thread seems to be a possible solution; will be interesting to see if it works.
