Disk quota configuration

Achieve disk quota

1. Enable the disk quota mount option under the home home directory

Vim / etc/fstab

# you can call UUID through ringing blkid / dev/sdb1 under vim

UUID= "3dfbe3a8-6264-4ceb-a835-abebe14f3eaf" / home ext4 usrquota,grpquota 0 0

# use in boot mode

Mount / dev/sdb1 / home/

# if the fstab configuration file is modified, you can use:

Mount-o remount / dev/sdb1 / home/

Centos7 needs to be mounted or restarted like [root@centos7] # mount-o usrquota,grpquota / dev/sdb1 / home/

2. Create a user disk quota database

Quotacheck-cug / home / / if there is a permission problem, you can execute getenforce to check whether selinux is closed, and if it is on, execute setenforce 0 to close it.

Setenforce 0 / / centos 6 needs to be closed. Centos7 is closed by default.

3. Enable the database

Quotaon-p / home to see if the database is enabled

Quotaon / home enable database

4. Configure quota entries

Edquota wang

# edquota-p wang mage / / copy the hard disk quota configuration of wang users to mage users

Setquota tom 100000 150000 00 / home / / set tom user capacity 100m alarm up to 150m, if not enough to modify the configuration capacity

5. Test

Quota wang / / View disk quotas for wang users

Repquota / home / / View disk quotas for all users under home
