How to Fix io wait issue in Linux

Linux high IOwait is a common Linux performance issue. Today we will look at what iowait means and what contributes to this problem. Hope this can give you more ideas about high IOwait issue.

What is IOwait?

IO wait is related to the CPU resource on the server.

The iowait column on top command output shows the percentage of time that the processor was waiting for I/O to complete. It indicates that the system is waiting on disk or network IO. Because the system is waiting on those resources, it can not fully utilize the CPU.

While there is no way to actually switch a VDI between fixed-size and dynamic, you can clone the existing VDI into a new one with different settings with VBoxManage.

VBoxManage clonehd [old-VDI] [new-VDI] --variant Standard
VBoxManage clonehd [old-VDI] [new-VDI] --variant Fixed

If you want to expand the capacity of a VDI, you can do so with

modCli; using MODX on the commandline.

modCLI

modCLI is a wrapper for the MODX Revolution Processors, allowing you to pretty much do anything from the commandline that you would normally do within the manager.

To use modCLI, simply download the modcli.php file and put it in the MODX_BASE_PATH of your installation. Next open up the console or terminal, and start firing some commands at it.
