ZFS newbie: pools/mounts not surviving reboots?

[Doug Poland]

Hello,

I'm a newbie when it comes to ZFS and am doing some experimentation to
get up-to-speed.  I've been using the man pages, wiki and freebsd-fs
for reference.

Right now I'm running in a VM on 7.x i386.  I've created a pool with
the intention of housing /var  :

# zpool create zfs01 da7
# zfs create zfs01/var
# dump -0aLC8 -f- /var | ( cd /zfs01/var && restore -rf- )
# zfs set mountpoint=/var zfs01/var
# df -h
Filesystem            Size    Used   Avail Capacity  Mounted on
/dev/mirror/gm0s1a    989M    128M    782M    14%    /
devfs                 1.0K    1.0K      0B   100%    /dev
/dev/da3s1d           989M    468K    910M     0%    /var
/dev/da4s1d           989M     12K    910M     0%    /tmp
/dev/da5s1d           989M    390M    520M    43%    /usr
/dev/da6s1d           989M    180K    910M     0%    /home
zfs01                 983M    128K    983M     0%    /zfs01
zfs01/var             984M    640K    983M     0%    /zfs01/var
fbsd7xvm# zfs set mountpoint=/var zfs01/var
fbsd7xvm# mount
/dev/mirror/gm0s1a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/da3s1d on /var (ufs, local, soft-updates)
/dev/da4s1d on /tmp (ufs, local, soft-updates)
/dev/da5s1d on /usr (ufs, local, soft-updates)
/dev/da6s1d on /home (ufs, local, soft-updates)
zfs01 on /zfs01 (zfs, local)
zfs01/var on /var (zfs, local)


Ok, so far so good.  My ZFS pool is mounted under /var.  However,
after I reboot, the pool is no longer mounted

# df -h
Filesystem            Size    Used   Avail Capacity  Mounted on
/dev/mirror/gm0s1a    989M    129M    781M    14%    /
devfs                 1.0K    1.0K      0B   100%    /dev
/dev/da4s1d           989M     12K    910M     0%    /tmp
/dev/da5s1d           989M    390M    520M    43%    /usr
/dev/da6s1d           989M    184K    910M     0%    /home

# zfs list
NAME        USED  AVAIL  REFER  MOUNTPOINT
zfs01       648K   983M    18K  /zfs01
zfs01/var   528K   983M   528K  /var


So what am I doing wrong?
