I had been updating/porting Steve Hartland's patches for zfs trim on mps for 8.3 stable. Trim was working fine for me before r249939. When I saw that this functionality was being added to current, I built world/kernel without the patches. Indeed, many of the commits are quite similar to the updated patch I worked on (patch claims most of it is 'already applied'). HOWEVER, I am not seeing a delete method detected for either of my Samsung 830s, which I did under my updated patch. It looks like scsi ata identify is not working. Are there still outstanding commits to enable this, or is something now a tunable/sysctl I'm missing? Previously it was working: kstat.zfs.misc.zio_trim.bytes: 47546368 kstat.zfs.misc.zio_trim.success: 2618 kstat.zfs.misc.zio_trim.unsupported: 0 kstat.zfs.misc.zio_trim.failed: 0 Current: kstat.zfs.misc.zio_trim.bytes: 0 kstat.zfs.misc.zio_trim.success: 0 kstat.zfs.misc.zio_trim.unsupported: 264 kstat.zfs.misc.zio_trim.failed: 0 kern.cam.da.3.delete_method: NONE kern.cam.da.3.delete_max: 0 kern.cam.da.4.delete_method: NONE kern.cam.da.4.delete_max: 0 Thanks, Matt
