One of the files that the average Unix sysadmin rarely looks at, almost never changes and yet depends on every time he or she reboots a system is the /etc/inittab file.
To wrap this year, I’ve collected 50 UNIX / Linux sysadmin related tutorials that we’ve posted so far. This is lot of reading. Bookmark this article for your future reference and read it whenever you get free time.
Linux is the Swiss Army knife of file systems, and it also offers a wide variety of storage technologies for both desktops and servers. Beyond the file system, Linux incorporates world-class NAS and SAN technologies, data protection, storage management, support for clouds, and solid-state storage. Learn more about the Linux storage ecosystem and why it's number one in server market share.
UNIX's method of handling file systems and volumes provides you with an opportunity to improve your systems' security and performance. This article addresses the issue of why you should split up your disk data into multiple volumes for optimized performance and security.
If those ‘Funny Linux Man Pages’ didn’t make you laugh, perhaps these manual pages developed on alt.sysadmin.recovery (asr) will do. ASR manpages document a set of really useful tools that for some strange reason are not included in any implementation of Unix.Once again, a little warning: View these man pages at your own risk, as you may find some of them rather offensive...
This tutorial shows how to set up a high-availability storage with two storage servers (Ubuntu 12.10) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Ubuntu 12.10 as well) will be able to access the storage as if it was a local filesystem.
