If your using CAM backed disks can you let me know what your seeing for 1. sysctl kern.cam.da | grep delete_method 2. sysctl vfs.zfs.trim The reason I ask is I'm investigating an issue with ZFS TRIM, reported by Ajit Jain, and it tests that have just completed potentially indicate an issue with either CAM or LSI's firmware when processing Write Same requests. Such requests may be used the ZFS TRIM depending on the underlying HW.
