[-- Attachment #1 --] Btw: The /etc/rc.d/zpool script looks into these cachefiles: for cachefile in /etc/zfs/zpool.cache /boot/zfs/zpool.cache; do I didn’t check where the cachefile pool property is used. Hope this helps resolving the issue. Or maybe helps you to provide more information about your setup. Regards, Ronald.
