OpenVZ taking ages to assign an IP to a container

MrAndroid

Hey,

Im using "vzctl set --ipadd --save" to add an IP address to a container, however once I do it it takes roughly two mins to finally return.

However, around 5 seconds after i've entered it, I can look at vzlist and enter the VPS and notice that its fine and its assigned it, so I am wondering why vzctl is taking ages to return the function after its done it?

run it through an strace

It's quite possible it's waiting on processes to finish reloading/etc to bind the address. If you got NAMED running, i've seen it hang pretty bad.

Ok i'll give it a go, its not a major issue, its just going to be a pain to implement in my scripts however.

Don't know

Heres the strace output, it was pretty fast this time though

Try strace -t next time, please Or strace -tt

MrAndroid

Ok, I think I've fixed it.

However, is it me or do the CentOS templates off the OpenVZ website not have a /etc/network/interfaces file? The debian ones doo.

rds100

For CentOS it is /etc/sysconfig/network-scripts/ifcfg* instead

Then why does OpenVZ spit in this error and the VPSs don't have network on CentOS

CentOS networking is handled through the files in /etc/sysconfig/network-scripts/, ifcfg-eth0 in particular. They like being difficult like that :P

@Daniel something is wrong with your vzctl. There is /etc/vz/dists/*.conf and /etc/vz/dists/scripts/ which makes vzctl behave in a different way (i.e. touch different files) depending on the distribution of the container.

I think I'm missing CentOS then

For CentOS it is redhat-add_ip.sh
Byt see in the /etc/vz/dists/ if there is a corresponding centos.conf
Also what exactly is the template name of that container?
i.e. grep OSTEMPLATE /etc/vz/conf/XXX.conf

MrAndroid

Yes there is a centos.conf

ADD_IP=redhat-add_ip.sh
DEL_IP=redhat-del_ip.sh
SET_HOSTNAME=redhat-set_hostname.sh
SET_DNS=set_dns.sh
SET_USERPASS=set_userpass.sh
SET_UGID_QUOTA=set_ugid_quota.sh
POST_CREATE=postcreate.sh

Template name is centos-6-x86_64.tar.gz

MrAndroid

I've noticed that the VPSs configuration file still contains the old template,

rds100

This is very strange because according to your strace vzctl thinks that this is a debian 6 VPS, see this line:

stat("/etc/vz/dists/debian-6.0-x86_64.conf", 0x7fffa4b0c460) = -1 ENOENT (No such file or directory)

So it executes the scripts for debian VPS.

rds100

I've noticed that the VPSs configuration file still contains the old template,

Edit it then, change OSTEMPLATE to centos-6-x86_64 and this should fix it.

MrAndroid

Ok, I just gotta make a script that automates it

MrAndroid

Stupid me, I forgot you can set --ostemplate with vzctl set, and I had just finished the sed command.
