Quotas

###Quotas###

Features:

1. Limits disk usage (blocks or inodes)

2. Tied to file systems (set on a per file system basis)

3. Can be configured for users and groups

Steps to enable quota support:

1. Enable quota support per file system in: /etc/fstab

a. defaults,usrquota,grpquota

2. Remount the file system(s)

a. mount -o remount /

b. use 'mount' to confirm that 'usrquota,grpquota' support are enabled

3. Create quota database files and generate disk usage table

a. quotacheck -mcug / - this creates /aquota.user & /aquota.group

b. quotacheck -mavug

4. Assign quota policies

a. edquota username - set blocks/inodes soft_limits hard_limit

edquota student1 - sets quotas for user 'student1'

export EDITOR=nano - to have edquota default to 'nano' editor

5. Check quotas

a. quota username

quota student1

Note: place 'quotacheck -avug' in /etc/cron.*(hourly,daily)

6. Report on usage

a. repquota -a - this reports on usage

Note: The blocks are measured in 1K increments. i.e. 20000 blocks is roughly 20MB
