After a reboot I have a zpool missing. I have to import it manually.
The script /etc/rc.d/zpool seems to be the culprit in that it
processes two zpool cache files :
t#
t# cat /etc/rc.d/zpool
#!/bin/sh
#
#
# PROVIDE: zpool
# REQUIRE: hostid disks
# BEFORE: mountcritlocal
# KEYWORD: nojail
. /etc/rc.subr
name="zpool"
desc="Import ZPOOLs"
rcvar="zfs_enable"
start_cmd="zpool_start"
required_modules="zfs"
zpool_start()
{
local cachefile
for cachefile in /etc/zfs/zpool.cache /boot/zfs/zpool.cache; do
if [ -r $cachefile ]; then
zpool import -c $cachefile -a -N
if [ $? -ne 0 ]; then
echo "Import of zpool cache
${cachefile} failed," \
"will retry after root mount hold
release"
root_hold_wait
zpool import -c $cachefile -a -N
fi
break
fi
done
}
load_rc_config $name
run_rc_command "$1"
t#
However neither of those cache files seem to hold information about
anything other than the pool created during installation.
There is a cachefile property in a zpool but that vanishes after a
reboot.
So then .. whats the magic here?
