Disk quota inside LXC container.

Tutorial how to enable quota in ISPCONFIG

I Run "quota with ISPCONFIG" and its running ok


1.On proxmox server uncoment:
"lxc.aa_profile = lxc-container-default-with-mounting" in
/usr/share/lxc/config/debian.common.conf
next reboot server

2.Make some CT debian 8.6 from my modify debian with sytemd working : https://forum.proxmox.com/threads/debian-8-6-lxc-template-with-systemd-feature-request.30212/

in /etc/pve/lxc/ find your CT ex. 101.conf
and add lines:
lxc.aa_profile: unconfined
mount -o remount,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 /

Its very important to add this lines becouse CT will not work without that!

3.Login to your CT and on bash write:
"df"
You shoul see which is your base system loop
exl. /dev/loop0 or /dev/loop1 ...

4. open:
nano /etc/fstab and add this line:
/dev/loop0 / ext4 errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0 1

i your loop was not 0 but 1 or something els just rename it to loop1 loop2......

Important thing is quota will not working after reboot of CT so make a script to run this every boot:in CRON:
a)
nano /etc/init.d/mystartup.sh

b)
Insert in file:

#!/bin/bash
echo ^ ^ Setting up customized environment ^ ^ ^

mount -o remount /
quotacheck -avugm
quotaon -avug

c)
make executable file:
chmod +x /etc/init.d/mystartup.sh
update-rc.d mystartup.sh defaults 100
--------------------------------------
Now you may Install ISPCONFIG with working quota.

AWARE that this tut will chcange CT to insecure.

If someone has a better tut or make some scipt to automate this that will be great.

Hi
Does quote only works on rootfs? I have a container with an additional mount point on which I enabled quota (via webgui). But it doesn't work as expected:

quotacheck -vguma
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.

After that I enabled quota also for the rootfs and there it seems to work:

cat /etc/mtab
/dev/rbd0 / ext4 rw,relatime,stripe=1024,data=ordered,jqfmt=vfsv0,usrjquota=aquota.user,grpjquota=aquota.group 0 0
/dev/rbd2 /mnt/ceph ext4 rw,relatime,stripe=1024,data=ordered 0 0
...

The configuration looks like this:

arch: amd64
cores: 4
hostname: samba
memory: 2048
mp1: ceph-data:vm-207-disk-1,mp=/mnt/ceph,quota=1,size=48G
nameserver: 8.8.8.8
net0: name=eth0,bridge=vmbr0,gw=192.168.101.10,hwaddr=##:##:##:##:##,ip=192.168.101.42/24,type=veth
ostype: debian
rootfs: ceph-lxc:vm-207-disk-2,quota=1,size=8G
searchdomain: 192.168.101.5
swap: 2048

What I have to do that quota also works on mount points?
Thanks in advance!

This does not work.

"vm 202 - lxc.aa_profile is deprecated and was renamed to lxc.apparmor.profile"

secondly a naked remount command in an lxc.conf file?

"vm 202 - unable to parse config: mount -o remount,usrjquota=aquota.user,grpjquota=aquota.group,jqfmt=vfsv0 /"

Doesnt seem correct.

I cannot turn on quota on the container in the GUI, it is greyed out despite being an ext4 fs on a zvol.

I have this problem but I can not find a solution cpanel
proxmox v5-4-6 + CENTOS 7.4 lxc + cpanel v80.0.11
Filesystem quotas are currently disabled. Click to enable
