Now that ken@ has checked in the SMR code I'm wondering how I can see whether it's having any effect. I have a 8TB SMR disk in a USB3 enclosure. Does the kernel emit any sort of trace to indicate that it sees the drive as SMR and takes that into account? I have the probe trace enabled in my kernel config, but I don't see anything special pop out when I turn the drive on. Does the fact that the drive appears as a /dev/daX play any role? BTW the disk returns an error when multiple LUNs are probed. -- Gary Jennejohn
