3.5.1 Matrix Server Command Reference

Chapter 1: Matrix Server Commands 6

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

Enables quotas on the filesystem.

userdefault=<size>

groupdefault=<size>

Set the default quota limit for users or groups, respectively, to size bytes.

(The defaults are rounded down to the nearest filesystem block.) The

<size> argument can include one of these 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.

The userdefault and groupdefault parameters are invalid if the

enable-quotas parameter is not also specified.

The following command shows the syntax for the quotas parameters:

mkpsfs -o enable-quotas,userdefault=#[T|G|M|K],

groupdefault=#[T|G|M|K] dev

If no -o options are specified, the filesystem will be created with Full Zone Bit

Maps (FZBM) and without quotas.

mpdump – save membership partition data

Synopsis

/opt/polyserve/lib/mpdump

mpdump [-v] -F

mpdump [-v] -f <outputfile>

Description

The mpdump utility backs up the membership partition data to a file and/or

the screen. When mpdump is run with no options, the data is output to the

screen.
