Hi,
You have a similar question here.
https://lists.freebsd.org/archives/freebsd-current/2024-November/006736.html
Is this about the same machine/setup?
Do the replies in that thread answer your current question about the cachefile property?
Regards,
Ronald

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