When importing pools with zpool import -aN there is inconsistent behavior between '-d /dev/disk/by-id' (or another path) and '-c /etc/zfs/zpool.cache'. The difference in behavior is caused by zpool_find_import_cached() returning an empty nvlist_t when there are no pools to import but zpool_find_import_impl() returns NULL for the same situation. The behavior of zpool_find_import_cached() is arguably more correct because it allows returning NULL to be used for an error case and not an empty set. This change resolves the issue by updating get_configs() such that it returns an empty set instead of NULL when no config is found. The updated behavior will now always return 0 for this case. $ zpool import -aN; echo $? no pools available to import 0 $ zpool import -aN -d /var/tmp/; echo $? no pools available to import 0 $ zpool import -aN -c /etc/zfs/zpool.cache; echo $? no pools available to import 0 Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #2080 |
