I upgrade another system to 9.0-RC1 and encounter the same problem, this
time zfsloader do not run.
After
mv /mnt/boot /mnt/Boot
mkdir /mnt/boot
cd /mnt/Boot
find . | cpio -pvdmu /mnt/boot
FreeBSD boot OK
[root@avoriaz zfsboottest]# ./zfsboottest /Boot/zfsloader /dev/ada0p2
/dev/ada1p2
ZFS: SPA version 28
pool: rpool
config:
NAME STATE
rpool ONLINE
mirror ONLINE
ada0p2 ONLINE
ada1p2 ONLINE
ZFS: i/o error - all block copies unavailable
can't lookup
10 minutes later:
[root@avoriaz zfsboottest]# ./zfsboottest /Boot/zfsloader /dev/ada0p2
/dev/ada1p2|less
ZFS: SPA version 28
pool: rpool
config:
NAME STATE
rpool ONLINE
mirror ONLINE
ada0p2 ONLINE
ada1p2 ONLINE
<blablabla>
it seems ok :-o
and a other time:
[root@avoriaz zfsboottest]# ./zfsboottest /Boot/zfsloader /dev/ada0p2
segmentation fault...
Strange isn't it.
