January 11, 201313 yr See image; note that my parity drive is id'd as sdj and there is no sdb. Does this matter at all and if it does, how do I correct. Dan
January 11, 201313 yr Does not matter at all. sdx assignments are ephemeral. The sdX device IDs are assigned by Linux in the order in which the drive spin up and initialize and present themselves to the OS through their disk controllers. The spin up times with multiple identical/nearly identical drives frequently causes the drives to initialize in a different order. unRAID used the disk controller port in the 4.X series and early 5.X beta releases to keep track of a drive assignment... until it was discovered where on one user's system, multiple disk controllers initialized in a different order at times, and as a result the disks all got new device /dev/sdX assignments. The next release changed to using the model/serial numbers of the disks themselves. The disk controller ports and /dev/sdX device names can change from one boot to the next, or even from one motherboard/disk controller to the next, and as long as the disk model/serial number do not change, unRAID will figure it out and use the disks as assigned.
