Should I be getting trim with ZFS on an mps device? Disks are SATA ssd (830s), only "unsupported" is being reported. Do I need to set the cam "da" delete method to something (unmap?), or is ZFS trim only supported on ahci sata controllers? vfs.zfs.trim_disable: 0 vfs.zfs.trim_txg_limit: 64 kstat.zfs.misc.zio_trim.bytes: 0 kstat.zfs.misc.zio_trim.success: 0 kstat.zfs.misc.zio_trim.unsupported: 281 Matt
