Hello and merry Xmas to everybody,
I upgrade a remote server from 8.1-RELEASE to 8.2-RC1.
This server have one disk:
[root@tignes ~]# gpart show
=> 63 488397105 ada0 MBR (233G)
63 12583809 1 freebsd (6.0G)
12583872 475813296 2 freebsd [active] (227G)
=> 0 12583809 ada0s1 BSD (6.0G)
0 8388608 1 freebsd-ufs (4.0G)
8388608 4195201 2 freebsd-swap (2.0G)
=> 0 475813296 ada0s2 BSD (227G)
0 475813296 1 freebsd-zfs (227G)
It boot with zfsboot from ada0s2 containing a zfs pool.
After upgrading the zfsboot just to be able to upgrade the pool to v15,
the server don't boot anymore.
It is a remote server, so I reproduce this config under VirtualBox. The
boot freeze after zfsboot displaying "-".
I grab a old zfsboot from another server running 8.1-STABLE (r213582)
which boot fine.
I put the zfsboot from r213582 (zpool v15 aware) on ada0s2 and bingo,
the server boot normally.
Henri
