There a two "quota systems" used by OpenVZ:

1 Level Quota:

Space Hostnode to Container:
Is set by --diskspace barrier:limit (/--diskinode barrier:limit) config how much a container can use the diskspace/indodes on the hardwarenode

2 Level Quota:

Is how many User/Group in this container can use the space above, set by --quotaugidlimit num (= limit of quota u(ser) g(roup)id) set how many User/Groups ID are accounted).
Add line:

/etc/sysconfig/vz-scripts/{VEID}.conf
QUOTAUGIDLIMIT="5000"

Reboot the VM:
vzctl restart ...

Code: Select all

pure-ftpd: (?@?) [ERROR] Unable to switch capabilities : Operation not permitted

1. Solution

Recompile Pure-FTPd with "--without-capabilities" option.

2. Solution
Find what's wrong with capabilities and add missing capability to your VE with vzctl command:

Code: Select all

#vzctl set <VEID> --capability capname:on|off

For Pure-FTPd:

Code: Select all

for CAP in CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE; do vzctl set <VEID> --capability ${CAP}:on --save;done

If you want to print UBC(/proc/user_beancounters) values for a specific container, the following construct can be helpful:

Code: Select all

egrep -A23 '^[[:space:]]+${CTID}:'

Here ${CTID} is the ID of the container you are interested in.

In case you want to print UBC values for a few containers at once, set CTID to something like (101|102|103).

Receiving the following error during VM start:

Code: Select all

#vzctl start <veid>

Starting VPS ...
vzquota : (warning) Incorrect quota shutdown for id <veid>, recalculating disk usage
vzquota : (error) quota check : lstat `conf': No such file or directory
vzquota on failed [1]

I fixed it by running the following commands:

Code: Select all

vzquota off <veid>     
vzquota on <veid>

vzctl start <veid>

VPN via the TUN/TAP device

Kernel TUN/TAP support

OpenVZ supports VPN inside a container via kernel TUN/TAP module and device. To allow container #101 to use the TUN/TAP device the following should be done:

Make sure the tun module has been already loaded on the hardware node:

Code: Select all

lsmod | grep tun

If it is not there, use the following command to load tun module:

Code: Select all

modprobe tun

You can also add it into /etc/modules.conf to make ...

There are two steps to configure the csf in vps:

1. Main vps server ( The host server, in which the vps nodes are running) configuration
2. Vps node configuration.

Let's proceed.

1. Main VPS server configuration

Before starting the CSF installation in a node login to the main server (host server) and check whether the following modules are inserted in to the kernel
