| 1. A method to check consistency of an aggregate capable of supporting flexible volumes, the method comprising:
identifying an inode having a flexible volume type present in the aggregate;
storing the inode in an inode scan list in response to the identifying;
determining whether the inode is identified in a metadata directory of the aggregate;
storing the inode in a discovered list if the inode is identified in the metadata directory; and
performing a consistency check on the flexible volume associated with the inode if the inode is in the inode scan list and
in the discovered list.
