If the root directory does not contain a quotas file, the mount command succeeds, but quotas
are not turned on.
Example A-14 To create a quotas file (if it does not already exist) and turn on
quotas for a VxFS file system mounted at /mnt
Enter:
# touch /mnt/quotas
# quotaon /mnt
Example A-15 To turn on quotas for a file system at mount time
Enter:
# mount -F vxfs -o quota /dev/vx/dsk/fsvol/vol1 /mnt
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
filesystem; 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
