I believe this is working as designed. A cache is kept in /etc/zfs/zpool.cache which contains a list of the devices and pools which should be imported automatically at boot time. The alternative is to scan every device, which does not scale well to large systems and can cause consternation for shared storage clusters. When you changed the motherboard, you also changed the device list, which is why the pools were not imported automatically at boot. This is an unusual case, but the solution is to export (thus removing the entries from zpool.cache) and import (adding new entries to zpool.cache) -- richard > Here is the description of the label
