500 error for all the domains on your cPanel Clould Linux server.

Latest  MySQL governor version will break mysqli if your server is running CloudLinux witn mysql 5.5 version

I have fixed this issue my recompiling the apache by disabling Mysqli php extension.

If your domains are using Mysqli then remove  MySQL governor and recompile the apache again with the default settings.

moving one vm from one disk to another disk

Moving your openVZ container from one disk to another disk in the same server.

That is moving vm locally on the server. Normally we are doing this when your current Hard disk space is over.

Let say the new disk is mounted on your server as disk2

We are trying to migrate a vm (2013 CTID) to disk 2

1. cd /disk2/
mkdir private
mkdir 2002
2. cp -a /var/lib/vz/private/2013/* /disk2/private/2013/

3. vzctl stop 2013   => stop the vm

4. vzquota drop 2013  => drop the quota , otherwise you will find some quota related issues.


Then edit the config file and enter the new VE_PRIVATE value,

5. vi /etc/vz/conf/2013.conf

VE_PRIVATE="/disk2/private/2013"  

6. mv /var/lib/vz/private/2013  /var/lib/vz/private/2013.bak  //taking backup to restore if needed, once successfully you can remove this file

*Start the vps

7. vzctl start 2013
