Turning On and Off Per-Container Disk Quotas
The parameter that defines whether to use first-level disk quotas is DISK_QUOTA in the global
configuration file (/etc/vz/vz.conf). By setting it to “no”, you will disable disk quotas
completely.
This parameter can be specified in the Container configuration file
(/etc/vz/conf/<CT_ID>.conf) as well. In this case, its value will take precedence of the
one specified in the global configuration file. If you intend to have a mixture of Containers with
quotas turned on and off, it is recommended to set the DISK_QUOTA value to yes in the global
configuration file and to no in the configuration file of that Container which does not need
quotas.
The session below illustrates a scenario when first-level quotas are on by default and are turned
off for Container 101:
[checking that quota is on]
# grep DISK_QUOTA /etc/vz/vz.conf
DISK_QUOTA=yes
[checking available space on /vz partition]
# df /vz
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda2 8957295 1421982 7023242 17% /vz
[editing Container configuration file to add DISK_QUOTA=no]
# vi /etc/vz/conf/101.conf
[checking that quota is off for Container 101]
# grep DISK_QUOTA /etc/vz/conf/101.conf
DISK_QUOTA=no
# pctl start 101
Starting Container ...
Container is mounted
Adding IP address(es): 10.0.16.101
Hostname for Container set: ve101
Container start in progress...
# pctl exec 101 df
Filesystem 1k-blocks Used Available Use% Mounted on
vzfs 8282373 747060 7023242 10% /
As the above example shows, the only disk space limit a Container with the quotas turned off
has is the available space and inodes on the partition where the Container private area resides.
