How to Set Up User Quotas
You can set user quotas with the edquota command if you have superuser privileges. User quotas can have a
soft limit and/or hard limit. You can modify the limits or assign them specific values. Users are allowed to
exceed the soft limit, but only for a specified time. Disk usage can never exceed the hard limit. The default
time limit for exceeding the soft limit is seven days on VxFS file systems.
edquota creates a temporary file for a specified user. This file contains on-disk quotas for each mounted VxFS
file system that has a quotas file. The temporary file has one or more lines similar to:
fs /mnt blocks (soft = 0, hard = 0) inodes (soft=0, hard=0)
fs /mnt1 blocks (soft = 100, hard = 200) inodes (soft=10, hard=20)
Quotas do not need to be turned on for edquota to work. However, the quota limits apply only after quotas are
turned on for a given file system.
edquota has an option to modify time limits. Modified time limits apply to the entire file system; you cannot
set time limits for an individual user.
To invoke the quota editor, use the syntax:
edquota username
To modify the time limit, use the syntax:
edquota -t
How to View Quotas
The superuser or individual user can view disk quotas and usage on VxFS file systems using the quota
command. To view quotas for a specific user, use the syntax:
quota -v username
This command displays the user’s quotas and disk usage on all mounted VxFS file systems where the quotas
file exists. You will see all established quotas regardless of whether or not the quotas are actually turned on.
How to Turn Off Quotas
You can turn off quotas for a mounted file system using the quotaoff command. To turn off quotas for a file
system, use the syntax:
quotaoff mount_point
Example
To turn off quotas for a VxFS file system mounted at /mnt, enter:
# quotaoff /mnt
