zpool_iter() passes the callback a new instance of zpool_handle_t each time, so the existing handle in the pool_list AVL never actually gets a refresh. Internally, that means its zpool_config is never updated, and the old config is never moved to zpool_old_config. As a result, print_iostat() never sees any updated config, and so repeats the first line forever. This is the simplest workaround: just don't mark existing pools as refreshed. pool_list_refresh() will see this and refresh them. The downside is a second call to ZFS_IOC_POOL_STATS for existing pools, because zpool_iter() just called it for the handle we threw away. Sponsored-by: Klara, Inc.
