4.1.0 HP PolyServe Software command reference guide (T5392-96071, October 2010)

--create-bitmap-file filename, -c filename
Saves bitmap of found leaves.
-y
Cause 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
article “Using the FZBM On-Disk Filesystem Format” on hp.com.
The options are:
--enable-fzbm
Enable the FZBM feature on the specified filesystem.
--disable-fzbm
Disable the FZBM feature on the specified filesystem.
The upgrade-fs and --downgrade-fs options are obsolete.
Upgrade filesystems for ADS support
Use the following option to upgrade a filesystem to support Alternate Data Streams
(ADS). Only those filesystems created on a Matrix Server release earlier than 3.6.1
need to be upgraded. Filesystems created on 3.6.1 (or later) releases automatically
include ADS support.
-e enableads
ADS and 8.3 support can be enabled in a single command, as shown below.
Manage 8.3 file creation and name tunneling
Use the following options to manage support for 8.3 short file names (SFN) and
name tunneling on a specific filesystem. These features should be enabled only if
you have a specific need for them, as the use of 8.3 files causes degradation in
filesystem performance. The degradation is proportional to the number of 8.3 files
created. If 8.3 SFN support is later disabled but 8.3 filenames exist, the performance
degradation will continue.
-e enable8dot3
