HP StorageWorks Clustered File System 3.6.0 Windows Storage Server Edition Administration Guide (403103-005, January 2008)

Chapter 9: Configure PSFS Filesystems 107
The -o option has the following parameters:
• blocksize=#
Specify the block size (either 4096 or 8192) for the filesystem.
• disable-fzbm
Create the filesystem without Full Zone Bit Maps (FZBMs). The FZBM
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.
• enable-quotas
Enable quotas on the filesystem.
The following options can be used with enable-quotas:
• default=<size>[K|M|G|T]
Set the default hard quota on the filesystem. (The default is rounded
down to the nearest filesystem block.) The <size> argument can
include one of the following optional modifiers to specify the unit: K
(kilobytes), M (megabytes), G (gigabytes), or T (terabytes). If one of
these modifiers is not specified, the <size> will be interpreted in bytes.
If the default quota limit is not specified on the command line, the
limit will be set to 0, which means there is no default limit.
• softdefault= <size>[T|G|M|K]
Set the default soft quota on the filesystem. The optional modifiers are
the same as default.
• static-default or dynamic-default
With static-default, quota limits for new users are copied from the
default quota values set for the filesystem. With dynamic-default,
quota limits for new users are linked from the default quota values set
for the filesystem. If the default quota values are changed, the users’
quota limits will also change. static-default is the default.
• loghardlimit or nohardlimit
Whether file operations that result in exceeding a user’s hard limit are
logged in the system event log. nohardlimit is the default.
