+.BI clone= dup|zero
+Resolve files with shared blocks in pass 1D by giving each file a private
+copy of the blocks (dup);
+or replacing the shared blocks with private, zero-filled blocks (zero).
+The default is dup.
+.TP
+.BI shared= preserve|lost+found|delete
+Files with shared blocks discovered in pass 1D are cloned and then left
+in place (preserve);
+cloned and then disconnected from their parent directory,

+or simply deleted (delete). The default is preserve.
+.TP
.BI ea_ver= extended_attribute_version
Set the version of the extended attribute blocks which

will require while checking the filesystem. The version number may
be 1 or 2. The default extended attribute version format is 2.
.TP
+.BI journal_only
+Only replay the journal if required, but do not perform any further checks
+or repairs.
+.TP
+.BI inode_badness_threshold= threshold_value
+A badness counter is associated with every inode, which determines the degree
+of inode corruption. Each error found in the inode will increase the badness by
+1 or 2, and inodes with a badness at or above
+.I threshold_value
+will be prompted for deletion. The default

.BI fragcheck
During pass 1, print a detailed report of any discontiguous blocks for
