Description

8567 changed the return value of zpool_read_label. Error paths that previously returned 0 began to return -1 instead. However, not all error paths initialized errno. When adding vdevs to a very large pool, errno could be prepopulated with ENOMEM, causing the operation to fail. Fix the bug by setting errno=ENOENT in the case that no ZFS label is found.

First reported at https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=226096 .
