5.4 Restricting the user’s disk space

When configuring disks under UNIX, system administrators can limit the disk space that can
be used by “normal” users.
Advanced Server for UNIX is configured by default to allow all free disk space to be used
by all AS/X users.
From Version 4.0B, Advanced Server for UNIX can be configured optionally to observe the
limit set under UNIX.

Furthermore, Advanced Server for UNIX supports the UNIX “quotas” function, which can
be used to restrict the disk space available to users on an individual basis.

The “quotas” function is currently only supported by UNIX on ufs file systems.

Since both functions use the same mechanisms under UNIX, the new functionality is
likewise controlled by the “UnixQuotas” registry parameter. The following table clarifies the
behavior of Advanced Server for UNIX depending on the different settings for the
“UnixQuotas” parameter:

UNIX commands are used for “quotas” to allocate the disk space for the respective UNIX
users. Should you require information on this topic, please refer to the UNIX system
documentation (

“System Administrator’s Guide”

) or the example given below.
