The xfs file system is different than the previous ext3/ext4 file systems.

This guide will be closely related to the standard quota setup guide, except that xfs may have a few extra steps that require more manual intervention.

If you need quotas setup on the /home partition, then the guide should be very similar to the standard quota setup guide.   However, if you need quotas setup on /, where / uses use an XFS partition (/home is only a directory under /), then extra steps are required.

As well, we replace the grpquota with pquota (project quotas), which will allow DA to setup directoy quotas, for things like enforcement of per-domain disk quotas.

To confirm what setup you have, run the df commmand, eg:

[root@es7-64 ~]# df -h

Filesystem               Size  Used Avail Use% Mounted on

/dev/mapper/centos-root   14G  2.3G   12G  17% /

devtmpfs                 915M     0  915M   0% /dev

tmpfs                    921M   24K  921M   1% /dev/shm

tmpfs                    921M  8.5M  912M   1% /run

tmpfs                    921M     0  921M   0% /sys/fs/cgroup

/dev/sda1                497M  125M  372M  26% /boot

[root@es7-64 ~]#

as you can see, /home is not a partition, so it falls under the / partition, so we must ensure that quotas are functional on the / partition.

0) Next confirm that / is actually using the xfs file system:

[root@es7-64 ~]# mount | grep ' / '

/dev/mapper/centos-root on / type xfs (rw,relatime,attr2,inode64,noquota)

[root@es7-64 ~]#

if you see the "noquota" option, then you need to go to step 1, below.

If you don't see noquota, then you should be able to follow the standard quota setup guide, but adding uquota,pquota to the /etc/fsab, after the default option.

If you see "noquota" in the xfs mount options for the / partition

1) Because "noquota" is a default kernel mounting option, we must change it in the kernel boot options.

Edit the file:

vi /etc/default/grub

2) Find the line with the variable "GRUB_CMDLINE_LINUX", that might look like this (it may not look exactly the same, don't worry):

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto vconsole.keymap=us rhgb quiet"

3) We're going to take the mount options that we found from step 0), and add them to the end of the line.

- We're going to put them after a "rootflags=" variable.

- Add uquota,pquota.

It might look something like this:

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto vconsole.keymap=us rhgb quiet rootflags=uquota,pquota"

4) Now, based on that setup, we'll backup, then create a new grub.cfg file:

cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.orig

grub2-mkconfig -o /boot/grub2/grub.cfg

The path on some OSs has been changed to

/boot/efi/EFI/centos/grub.cfg

5) Lastly, we must reboot the box in order for the kernel to see these new options

reboot

6) We keep our fingers crossed that the box comes back, and login again.  Go back to step 0) to check the mounting options to ensure that "noquota" is gone, eg:

[root@es7-64 ~]# mount | grep ' / '

/dev/mapper/centos-root on / type xfs (rw,relatime,attr2,inode64,usrquota,prjquota)

[root@es7-64 ~]#

Once it's gone, we want to see usrquota,prjquota(or uquota,pquota, they're the same thing).

If you don't see, them, then add them to the / partition with the standard quota setup guide.

7) Ensure that DirectAdmin has xfs quotas enabled in the directadmin.conf:

cd /usr/local/directadmin

./directadmin c | grep use_xfs_quota

8) If there are already Users created in DA, then you'll also want to reset their quota limits:

echo "action=rewrite&value=quota" >> /usr/local/directadmin/data/task.queue

to ensure their upper disk usage limits are enforced.

vi /etc/default/grub

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto vconsole.keymap=us rhgb quiet"

    -------------

http://www.interworx.com/support/faq/enabling-quotas-centos7/

The release of EL7 marks the shift from Ext4 to XFS as the default filesystem for RHEL-based distros like CentOS. While XFS brings many improvements and features to the OS, user and group quotas are no longer enabled by default on the root (‘/’) partition.

While quotas are an optional feature, they are recommended to get the full InterWorx experience. Follow these steps from the command line to enable quotas:

First, check if quotas are enabled:

mount | grep ' / '

You should see ‘noquota’ if quotas are disabled, for example:

# /dev/mapper/centos_el7-root on / type xfs (rw,relatime,attr2,inode64,noquota)

Next, edit /etc/default/grub:

vi /etc/default/grub  Find the line beginning with GRUB_CMDLINE_LINUX and append the following:

rootflags=usrquota,grpquota

The line should end up looking something like this:

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_el7/root vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos_el7/swap crashkernel=auto vconsole.keymap=us rhgb quiet rootflags=usrquota,grpquota"

Backup the grub configuration:

cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.orig

For servers using EFI, the grub.cfg file is listed here: /boot/efi/EFI/centos/grub.cfg

Generate the new grub configuration:

grub2-mkconfig -o /boot/grub2/grub.cfg 

For EFI, use this command:  grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg

Reboot:

reboot

Verify success:

mount | grep ' / '

You should see quotas are now enabled:

/dev/mapper/centos_el7-root on / type xfs (rw,relatime,attr2,inode64,usrquota,grpquota)

ERROR

Disk Usage is show

# /usr/sbin/repquota /home     OR        /usr/sbin/repquota /

If the "used" column is not showing anything, or users are not in the list, then you'll need to run the quotacheck program:

# /sbin/quotaoff -a; /sbin/quotacheck -avugm; /sbin/quotaon -a;

Enable Additional Repositories And Install Some Software

https://www.howtoforge.com/tutorial/perfect-server-centos-7-1-apache-mysql-php-pureftpd-postfix-dovecot-and-ispconfig3/

First we import the GPG keys for software packages:

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*

Then we enable the EPEL repository on our CentOS system as lots of the packages that we are going to install in the course of this tutorial are not available in the official CentOS 7 repository:

yum -y install epel-release

yum -y install yum-priorities

Edit /etc/yum.repos.d/epel.repo...

nano /etc/yum.repos.d/epel.repo

... and add the line priority=10 to the [epel] section:

[epel] name=Extra Packages for Enterprise Linux 7 - $basearch #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch failovermethod=priority enabled=1 priority=10 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7 [...]

Then we update our existing packages on the system:

yum update

Now we install some software packages that are needed later on:

yum -y groupinstall 'Development Tools'

7 Quota

(If you have chosen a different partitioning scheme than I did, you must adjust this chapter so that quota applies to the partitions where you need it.)

To install quota, we run this command:

yum -y install quota

Now we check if quota is already enabled for the filesystem where the website (/var/www) and maildir data (var/vmail) is stored. In this example setup, I have one big root partition, so I search for ' / ':

mount | grep ' / '

[root@server1 ~]# mount | grep ' / '

/dev/mapper/centos-root on / type xfs (rw,relatime,attr2,inode64,noquota)

[root@server1 ~]#

If you have a separate /var partition, then use:

mount | grep ' /var '

instead. If the line contains the word "noquota", then proceed with the following steps to enable quota.

Enabling quota on the / (root) partition

Normally you would enable quota in the /etc/fstab file, but if the filesystem is the root filesystem "/", then quota has to be enabled by a boot parameter of the Linux Kernel.

Edit the grub configuration file:

nano /etc/default/grub

search fole the line that starts with GRUB_CMDLINE_LINUX and add rootflags=uquota,gquota to the commandline parameters so that the resulting line looks like this:

GRUB_CMDLINE_LINUX="rd.lvm.lv=centos/swap vconsole.font=latarcyrheb-sun16 rd.lvm.lv=centos/root crashkernel=auto  vconsole.keymap=us rhgb quiet rootflags=uquota,gquota"

and apply the changes by running the following command.

cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg_bak

grub2-mkconfig -o /boot/grub2/grub.cfg

and reboot the server.

reboot

Now check if quota is enabled:

mount | grep ' / '

[root@server1 ~]# mount | grep ' / '

/dev/mapper/centos-root on / type xfs (rw,relatime,attr2,inode64,usrquota,grpquota)

[root@server1 ~]#

When quota is active, we can see "usrquota,grpquota" in the mount option list.

Enabling quota on a separate /var partition

If you have a separate /var partition, then edit /etc/fstab and add ,uquota,gquota to the / partition (/dev/mapper/centos-var):

nano /etc/fstab

#

# /etc/fstab

# Created by anaconda on Sun Sep 21 16:33:45 2014

#

# Accessible filesystems, by reference, are maintained under '/dev/disk'

# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info

#

/dev/mapper/centos-root /                       xfs     defaults        1 1

/dev/mapper/centos-var /var                     xfs     defaults,uquota,gquota        1 2

UUID=9ac06939-7e43-4efd-957a-486775edd7b4 /boot                   xfs     defaults        1 3

/dev/mapper/centos-swap swap                    swap    defaults        0 0

Then run

mount -o remount /var

quotacheck -avugm

quotaon -avug

to enable quota. When you get a error that there is no oartition with quota enabled, then reboot the server before you proceed.
