Once again a great FreeBSD book to read. I was anxious to read this after reading FreeBSD Mastery- Storage Essentials 2014. I read where he was writing a ZFS book, but didn't know it was out until I was asked to review it. I loved the introduction, being into hardware and history, it was such great knowledge. I knew some of this information prior, no where near as in depth as these authors covered. The style is so easy to read and mentally kind, it's always a pleasure to read. Of course ZFS has been used in other Oses (such as Solaris and Linux) and while it is not new to FreeBSD, many people are either afraid of it because they are moving from Linux or they have heard negative things about it.
Cloud storage is nothing but an enterprise-level cloud data storage model to store the digital data in logical pools, across the multiple servers. You can use a hosting company such as Amazon, Google, Rackspace, Dropbox and others for keeping your data available and accessible 24x7. You can access data stored on cloud storage via API or desktop/mobile apps or web based systems.
In this post, I'm going to list amazingly awesome open source cloud storage engines that you can use to access and sync your data privately for security and privacy reasons.
Can't write to the hard disk on a Linux or Unix-like systems? Want to diagnose corrupt disk issues on a server? Want to find out why you are getting "disk full" messages on screen? Want to learn how to solve full/corrupt and failed disk issues. Try these eight tips to diagnose a Linux and Unix server hard disk drive problems.
Cloning is nothing but the copying of the contents of a server hard disk to a storage medium (another disk) or to an image file. Disk cloning is quite useful in modern data centers for:
- Full system backup.
- System recovery.
- Reboot and restore.
- Hard drive upgrade.
- Converting a physical server to virtual machine and more.
In this post, I'm going to list the Free and Open Source Software for Disk Imaging and Cloning that you can use for GNU/Linux, *BSD and Mac OS X desktop operating systems.
Today I will be talking about ansible, a powerful configuration management solution written in python. There are many configuration management solutions available, all with pros and cons, ansible stands apart from many of them for its simplicity. What makes ansible different than many of the most popular configuration management systems is that its agent-less, no need to setup agents on every node you want to control. Plus, this has the benefit of being able to control you entire infrastructure from more than one place, if needed. That last point's validity, of being a benefit, may be debatable but I find it as a positive in most cases. Enough talk, lets get started with Ansible installation and configuration on a RHEL/CentOS, and Debian/Ubuntu based systems.
