what does `sysctl vfs.zfs.vdev.min_auto_ashift` say? > Sector Size: 512 bytes logical/physical The SSD is doing read-copy-update behind the scenes to support a 512-byte sector size for compatibility reasons, the real sector size is unlikely to be less than 4 kB and may actually be significantly larger.
