Okay, now I found it right in the zfsimpl.c if (val != POOL_STATE_ACTIVE) { /* * Don't print a message here. If we happen to reboot * while where is an exported pool around, we don't * need a cascade of confusing messages during boot. */ /*printf("ZFS: pool is not active\n");*/ return (EIO); } So it is wanted not to boot from an exported zpool? Why is that so? greetings, philipp
