int DUP I=int

Cause

Upon detecting a block that is already claimed by another inode, fsck(1M) prints the duplicate block number and its containing inode (after I=).

Action

In fsck(1M) phases 2 and 4, you will decide whether or not to clear these bad blocks. Before committing to repair with fsck(1M), you could determine which file contains this inode by passing the inode number to the ncheck(1M) command:

# ncheck -iinum filesystem
