I've seen it act a little funny with way large stripe sizes (65536), several different times I have seen it develop "non-writable" and "non-accessible" zones near the very end of the disk. I haven't had the time to explore why this is, but have instead worked around it by leaving the last 10% of the metadisks in question unpartitioned. Other than that: you gotta love ccd :-) ...
