first-level：per-VPS quotas
second-level：per-user and per-group quotas

First-level:

/etc/vz/vz.conf
..........
DISK_QUOTA=yes   <---- 可以 per VPS 設定
VZFASTBOOT=no
..........

每個 VPS 的 quota 使用情況記錄在 /var/vzquota/quota.vpsid

而 disk quota 的單位是1024 bytes

Space

Get:

vzquota stat <VEID>

Set:

vzctl set <VEID> --diskspace 10G:11G --save
vzctl set <VEID> --quotatime 600 --save
 

inodes:

Get:

vzctl exec <VEID> df -i

Set:

vzctl set <VEID> --diskinodes 200000:220000 --save

P.S.

# 若不打開該 VPS 的 first-level quotas，將不能使用second-level quotas設置.

Second-level

# vzctl set 1001 --quotaugidlimit 100 --save

# 100 - means that 100 users inside VE can be limited by disk quota.

直接一次過修改:

/etc/vz/conf/1001.conf
..................................
# Qutoa Setting 10G/200k  user:100
DISKSPACE="10000000:11000000"
DISKINODES="200000:220000"
QUOTATIME="600"
QUOTAUGIDLIMIT="100"

P.S.

現在(5-12-11) 支援 ext3/4 的 Second-level Quota

"Alert: Could Not Start Vps, Reason: vzquota : (error) Quota file check sum is invalid for id 14715; file is broken: vzquota on failed [4]:"

vzquota drop 14715
