default limit, click “Unlimited.”) The default quotas apply to all users and

groups; however, you can change the quota for a specific user or group.

To enable or disable quotas from the command line, use mx quota

command or the psfsquota or psfsck utilities. The psfsquota and psfsck

utilities provide the following options to enable or disable quotas on a

PSFS filesystem:

• --enable-quotas

Build the necessary quota infrastructure on the specified filesystem.

The psfsquota or psfsck utility then examines the existing files and

stores current allocations for each user and group owning a file on the

filesystem.

• --disable-quotas

Disable quotas on the specified filesystem and free the associated

blocks.

If you are enabling quotas, you can also set the default quota for users or

groups on that filesystem:

• --set-udq <size>[T|G|M|K]

Set the default quota for users on the specified filesystem. (The default

is rounded down to the nearest filesystem block.) The optional

modifiers specify that the size is in terabytes (T), gigabytes (G),

megabytes (M), or kilobytes (K). If a modifier is not specified, the size

will be calculated in bytes.

• --set-gdq <size>[T|G|M|K]

Set the default quota for groups on the specified filesystem. (The

default is rounded down to the nearest filesystem block.) The

modifiers are the same as the set-udq option.

The psfsquota command has this syntax:

/opt/polyserve/sbin/psfsquota [--enable-quotas] [--disable-quotas]

[--set-udq <size>[T|G|M|K]] [--set-gdq <size>[T|G|M|K]] [-y] <dev>

The -y option answers “yes” to all questions.
