Quotas limit the amount of disk space a filesystem can use. The traditional model of filesystems has changed with ZFS because of the introduction of pools. Each pool (which can be made up of a disk slice, a whole disk, or several disks) can have a jaw-dropping big number of filesystems created in a hierarchial manner. This tech-recipe describes the use of quotas with ZFS.
ZFS can compress data on filesystems. Some folks adamantly refuse to compress mounted filesystems, citing performance issues. While not every situation is appropriate, compression can increase system performance by improving IO at the cost of CPU. In most cases, disk IO, more than CPU, is rate determining. This tech-recipe describes turning on ZFS compression and checking its compression ratio status.
ZFS obsoletes many familiar filesystem maintenance commands. Creating a UFS filesystem involved partitioning a disk into slices (format), creating the filesystem (newfs), and mounting it (mount). ZFS does all of this in one simple command. This tech-recipe describes creating a ZFS pool which is the basic building block of filesystems created using ZFS.
The zpool command manages ZFS pools as shown in previous tech-recipes. Once a pool is created, its properties can been viewed with the list option of the zpool command.
Creating a basic if – then statement in flash or actionscript is easy. Here is the correct syntax.
When configuring a Spring project, it is either necessary to write extensive amounts of XML configuration code or to write moderate amounts of XML configuration code and enable annotations. When annotations are enabled, Spring parses the project’s Java beans in order to find these annotations. This allows the developer to push some of the configuring to the Java bean code instead of keeping it all in the XML configuration file. This guide will show you how to enable annotations in Spring.
The drop shadow is a simple way to create very noticeable depth on objects in your project. This tutorial will show you how to apply it effectively. Your elements will stand out whether you are working with image layers or blocks of text.
By default, Internet Explorer will remember your browsing history, cookies, and saved passwords. Over time, too many entries will accumulate, which will make managing your history and saved passwords difficult. If you are sure your browsing history does not contain any important data, you can delete it and start from scratch again.
Spam messages usually annoy modern mobile users. Many applications are available that will help you deal with spam. However, they usually run in the background, wasting phone resources and battery life. If you are a Samsung user, you can filter spam messages and numbers using a built-in feature.
For game and app development, developers are required to have an unlocked Windows Phone device. This process will walk you through all the necessary steps to get your phone unlocked so that you can test your app on a real device.
By default, android phone only notify new message once. The user may miss the incoming messages if he is currently busy. Setting the messaging app to repeatedly alert the unread messages will increase the awareness of the user about the messages. This tutorial will show you how to set up this feature without using any third-party applications.
The enable password is similar to the superuser or Administrator password and protects your Cisco router. Only after authenticating with this password can you make changes to your device.
