Saves bitmap of found leaves.
•-y
Causes psfscheck to answer “yes” to all questions.
Enable or Disable FZBMs
The psfscheck utility also provides options to enable or disable Full Zone
Bit Maps (FZBMs). This on-disk filesystem format reduces the amount of
data that the filesystem needs to read when allocating a block. It is
particularly useful for speeding up allocation times on large, relatively
full filesystems. For details about FZBM, see the HP Knowledge Base
article “Using the FZBM On-Disk Filesystem Format.”
The options are:
• --enable-fzbm
Enable the FZBM feature on the specified filesystem.
• --disable-fzbm
Disable the FZBM feature on the specified filesystem.
