The Wonderful World of Linux FileSystems! by Lee_Lammert.

Lee's BTRfs level 100 intro, part 1 of BTRfs 100/200/500 series, "Troubleshooting Grub Boot Failure", that was given last Wednesday at the monthly SLUUG general meeting, demonstrated recovering a BTRfs file system. Utilizing the features of the BTRfs file system allowed for the recovery of files that COULD have otherwise been lost!

So tonite... we back off a bit to look at "the big picture". This will give you that understanding that will prepare you. In a future meeting (or 2) we will get into the details, then into the intermediate level, as in Practical Ops (for sysadmins using Snapper, subvolumes, RAID, ...).

That will lead to Deep Internals, as in Engineering Analysis for kernel-savvy, file system experts.

Recordings and materials of last week's talk can be found in BRTfs File System Level 100 Introduction

This meeting is usually held the first Thursday of every month.

We hold an Online Linux Configuration Workshop when nothing else more interesting comes up, or when there is no other event or activity scheduled. Problems with other operating systems and hardware are also frequently fixed. New software tools are often demonstrated.

Linux is an Internet capable Networking Operating System that provides many fully functional applications that perform well on both older and new computers. Most Linux distributions are free or low cost and provides an extremely reliable and cost effective alternative to high priced proprietary software.

The online workshop is where we usually examine, troubleshoot, fix and repair difficult hardware and software configuration problems for Linux newcomers. We have have had considerable success solving problems remotely.

If we ever get back to face-to-face meetings*,* you would bring your laptop or PC to our hands on workshop to troubleshoot your Linux installation, network connection or X Window GUI configuration problem. We have full connectivity to the Internet on site and know how to use it. Just remember to bring your laptop or your PC with monitor, keyboard, mouse, cables, cords, power strips and two blank discs or a USB thumb drive.
