Solaris Disk Quotas

Disk Quotas under Solaris
*************************

Create a quotas file (on root of filesystem):
———————————————

# /usr/bin/touch quotas
# /usr/bin/chmod 600 quotas

Display user’s quota on all mounted file systems where quotas exist:
——————————————————————-

# quota -v username

which will output something similar to this:

Disk quotas for user1 (uid 1175):
Filesystem usage quota limit timeleft files quota limit timeleft
/var/spool/mail 0 3072 5144 1 0 0
/home 1377 3072 5144 146 0 0
/tmp 0 1024 1024 0 0 0

Set or reset disk quota for users:
**********************************

Set disk quota for a user:
————————–

# /usr/sbin/edquota username

The editor invoked is vi unless the EDITOR environment variable specifies otherwise.

fs /acct/s1 blocks (soft = 0, hard = 0) \
inodes (soft = 0, hard = 0)

Modify it as below:

fs /acct/s1 blocks (soft = 95000, hard = 100000) \
inodes (soft = 9000, hard = 10000)

Save it and quit.

Set disk quota for all users:
—————————–

Create the following script to set disk quota for all users:

# vi .EQ
#!/bin/sh
LOGINS=`/usr/bin/ls | grep -v quotas | grep -v lost+found \
| grep -v csestudent`
for LOGIN in $LOGINS;
do
/usr/sbin/edquota -p csestudent $LOGIN
done
# /usr/bin/chmod 500 .EQ
# ./.EQ

Set soft time limit:
——————–

The soft time limits are initially set to the values defined for DQ_FTIMELIMIT and
DQ_BTIMELIMIT in /usr/include/sys/fs/ufs_quota.h. The default value is 7*24*60*60
– 1 week. It is fine for general use, otherwise enter:

# /usr/sbin/edquota -t

Turn quotas on:
***************

# vi /etc/init.d/quotaon
#!/bin/sh
/usr/sbin/quotacheck /path/to/filesystem
/usr/sbin/quotaon /path/to/filesystem
# /usr/bin/chmod 500 /etc/init.d/quotaon
# vi /etc/rc2.d/S99quota
#!/bin/sh
if [ -x /etc/init.d/quotaon ]; then
echo ‘Starting quota…’
/etc/init.d/quotaon &
fi
# /usr/bin/chmod 500 /etc/rc2.d/S99quota
# /etc/rc2.d/S99quota

Give warning to users:
**********************

Because no warning is given when the user has exceeded the soft limit, so add the
following to /etc/cshrc:

#
# check disk quota when users login
#
set groupline=`/usr/bin/groups`
if ($groupline[1] == student || $groupline[1] == students) then
/usr/sbin/quota -v
endif
unset groupline
