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.

For details about FZBM, see the HP support document “Using the

FZBM On-Disk Filesystem Format” on the HP web site.

• 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.
