RedHat

Getting started with RHEL4's built-in LVM tools

Post date: June 3, 2005, 16:06 Category: System Views: 6061 Comments
Tutorial quote: Many Unix administrators I know (you know who you are), always used to smirk when I talked about Linux. They could always point to the fact that regardless of whatever I could say, they had journaling file systems, which they could manage using various Logical Volume Management (LVM) tools, and I couldn't touch that.

Well, not any more! Not only does Red Hat offer ext3 as their default file system, but they offer great management tools to boot. As we know, ext2 had a great lifespan, but it was not an enterprise-ready file system that could handle large disk partitions, fast recovery from systems crashes, or large amounts of files. Journaling file systems give you the ability to recover almost instantly from a crash, as you do not need to run fsck after a restart. Similar to how databases recover from crashes, a journaling file system tracks changes to file system metadata and pretty much guarantees that either all or no updates have completed. Of course, these file systems also need elaborate tools to help better configure and manage them accordingly.

Tutorial quote: SSH is one powerful tool. You can do just about everything under the sun using an SSH login to a remote computer. SSH works very well in low-bandwidth situations like dialup, or satlinks.

But wakeup, we’re no longer in the 80s - people want GUIs, let’s give them fancy-pants graphics, bouncing cursors and silly linux wizards. Remotely.

Splitting updatedb into daily and weekly

Post date: April 21, 2006, 12:04 Category: System Views: 2529 Comments
Tutorial quote: We all appreciate the locate command when we are such in a hurry we cannot afford a full and in-elegant find. What we like a little less, though, is the updatedb script consuming up all our disk bandwidth at each boot, summoned by anacron.

Of course, this is only the case if you are running a "desktop" machine: since you turn it on when you need to do some work, then you long for a way to shorten the period of reduced usability forced by updatedb.

Inversely, if you run a server that never goes down, and you successfully schedule your updatedb tasks late at night, then this article is not for you.
