During phase 1, fsck(1M) found duplicate blocks or bad blocks associated with the file or directory specified after FILE= whose inode number appears after I= (with other information).
To remove this file or directory, answer "yes." If you have to remove more than a few files in this manner, data can be lost. Therefore, it might be preferable to restore the file system from backup tapes.
For more information on checking file systems, see the section on checking file system integrity in the System Administration Guide, Volume 1.
