Currently FreeBSD ZFS kernel code doesn't allow to mount root filesystem on a pool that is not listed in zpool.cache as only pools from the cache are known to ZFS at that time. This patch is an attempt to improve the behavior: http://people.freebsd.org/~avg/spa_import_rootpool.diff This could be useful when importing pools that were exported from other systems. There is a tunable vfs.zfs.rootpool.prefer_cached_config which is set to 1 by default. 1 means just use a cached pool config if it's found in the cache, 0 means to re-probe disks and read supposedly latest/actual config in any case. -- Andriy Gapon
