So I rebuit with RAID5 and re-installed 12.0-CURRENT (r333982). But failed to boot with: ZFS: i/o error - all block copies unavailable ZFS: can't read MOS of pool zroot gptzfsboot: failed to mount default pool zroot FreeBSD/x86 boot ZFS: I/O error - blocks larger than 16777216 are not supported ZFS: can't find dataset u Default: zroot/<0x0>: In this case, the reason is "blocks larger than 16777216 are not supported" and I guess this means datasets that have recordsize greater than 8GB is NOT supported by the FreeBSD boot loader(zpool-features(7)). Is that true ? My zpool featues are as follows: # kldload zfs # zpool import pool: zroot id: 13407092850382881815 state: ONLINE status: The pool was last accessed by another system. action: The pool can be imported using its name or numeric identifier and the '-f' flag. see: http://illumos.org/msg/ZFS-8000-EY config: zroot ONLINE mfid0p3 ONLINE # zpool import -fR /mnt zroot # zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT zroot 19.9T 129G 19.7T - 0% 0% 1.00x ONLINE /mnt # zpool get all zroot NAME PROPERTY VALUE SOURCE zroot size 19.9T - zroot capacity 0% - zroot altroot /mnt local zroot health ONLINE - zroot guid 13407092850382881815 default zroot version - default zroot bootfs zroot/ROOT/default local zroot delegation on default zroot autoreplace off default zroot cachefile none local zroot failmode wait default zroot listsnapshots off default zroot autoexpand off default zroot dedupditto 0 default zroot dedupratio 1.00x - zroot free 19.7T - zroot allocated 129G - zroot readonly off - zroot comment - default zroot expandsize - - zroot freeing 0 default zroot fragmentation 0% - zroot leaked 0 default zroot feature@async_destroy enabled local zroot feature@empty_bpobj active local zroot feature@lz4_compress active local zroot feature@multi_vdev_crash_dump enabled local zroot feature@spacemap_histogram active local zroot feature@enabled_txg active local zroot feature@hole_birth active local zroot feature@extensible_dataset enabled local zroot feature@embedded_data active local zroot feature@bookmarks enabled local zroot feature@filesystem_limits enabled local zroot feature@large_blocks enabled local zroot feature@sha512 enabled local zroot feature@skein enabled local zroot unsupported@com.delphix:device_removal inactive local zroot unsupported@com.delphix:obsolete_counts inactive local zroot unsupported@com.delphix:zpool_checkpoint inactive local # Regards [1] https://lists.freebsd.org/pipermail/freebsd-current/2018-March/068886.html [2] https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=151910 --- KIRIYAMA Kazuhiko
