How to Turn On Quotas
You can enable quotas at mount time or after a file system is mounted. The root directory of the file system
must contain a file named quotas that is owned by root.
To turn on quotas for a mounted file system, use the syntax:
quotaon mount_point
To mount a file system and turn on quotas at the same time, use the syntax:
mount -F vxfs -o quota special mount_point
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.
