HP Clustered Gateway Device Management Software manual Disable-fzbm, Enable-quotas

Chapter 1: Matrix Server Commands 5

•For a psv device, the device is specified as /dev/psv/psvXXX, where XXX is the volume number. For example, /dev/psv/psv1.

You do not need to specify the full path name. A name such as psd6p4 or psv1 will work.

mkpsfs requires exclusive access to the device. If it cannot obtain exclusive access, it will exit with an “ebusy” message.

The arguments are as follows:

size-in-blocks

The number of blocks on the device. If this value is omitted, mkpsfs will determine it automatically.

-nmax-nodes

The maximum number of nodes that can be in the cluster.

-llabel

The label to be applied to the filesystem.

The -ooption has the following parameters:

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 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.

The userdefault and groupdefault parameters are invalid if the enable-quotasparameter is not also specified.
