$ SHOW QUOTA/USER=[DOCUMENTATION,ELAINE]
User [DOCUMENTATION,ELAINE] has 27305 blocks used, 2305 OVERDRAWN,
of 25000 authorized and permitted overdraft of 4000 blocks on DISK$
This SHOW QUOTA command indicates that a user has an overdrawn quota.
9.11.2.3 Suspending Quota Operations
The SYSMAN command DISKQUOTA DISABLE (which requires SYSPRV
privilege, a system UIC, or ownership of the volume), suspends quota operations
on a volume in the current management environment; the DISKQUOTA ENABLE
command lifts the suspension. You can also suspend quota operations on a
volume at mount time by specifying the /NOQUOTA qualifier with the DCL
command MOUNT. Disabling quotas requires privileges.
Whenever quotas are enabled on a volume—either implicitly with the MOUNT
command or explicitly with the DISKQUOTA ENABLE command—you must
update disk quota information using the command DISKQUOTA REBUILD. In
updating the quota file, the system adds new UICs and corrects usage counts
for each user. (Refer to the OpenVMS System Management Utilities Reference
Manual for more information.)
How to Perform This Task
To discontinue quota operations on a volume:
1. Log in to SYSMAN.
2. Use the following format to execute the DISKQUOTA DISABLE command on
each member of the cluster that is mounting the volume:
SYSMAN> DISKQUOTA DISABLE
3. Exit from SYSMAN.
4. Delete the QUOTA.SYS file in the top-level directory disk: [000000].
Note that the system does not suspend quotas across disk mounts if the
QUOTA.SYS file is still present.
9.11.3 Purging Files
One of the best ways to conserve disk space is to purge the following items:
• Old versions of files
Before purging files, make sure that the most recent versions are the ones
you want to preserve.
• System log files that the system generates automatically, such as the operator
log and accounting log files
• Log files created by the PRINT and SUBMIT commands
Encourage individual users to purge files in their own areas and directories.
If necessary, you can purge files from some or all directories. The following
examples show purge commands.
