Hi all,
I've been reported ZFS boot disable problem [1], and found
that this issue occers form RAID configuration [2]. 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.
