The Wonderful World of* Linux FileSystems*! by Lee_Lammert
<https://www.google.com/url?q=https://www.sluug.org/bio/Lee_Lammert&sa=D&sou…>
.
- What are File Systems?
- Why are there different types with different features?
- How do I choose?
- Do I WANT different types?
Last week at the monthly, general mtng on Wed, Lee Lammert
showed us how utilizing the features of the BTRfs file system allowed for
the recovery of files that COULD have 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
mtng (or 2) we will get into the details then into the intermediate /
Practical Ops (for sysadmins using Snapper, subvolumes, RAID,...)
That will lead to Deep Internals / Engineering Analysis (for kernel-savvy,
filesystem experts).
Lee's level 100 intro (that was a demo of recovering an FS) was
last Wed at the general mtng. Recordings and materials of last week's
talk can be found in http://sluug.org

6:30 ~ 9:00 PM ( Central Standard Time, USA )
**We will open the remote session at about 6:00 PM**
**Join early to test your microphone, screen and video sharing**
**** Microphone Or Webcam Are Not Required to Join ****
This ZOOM session will use the following link:
> https://us06web.zoom.us/j/83623171118?pwd=ESOFmqyEZAh5EVevxOxpjVmrMADtf0.1
The extant Saint Louis Area Computer Club (SLACC) is the oldest,
longest enduring, continuously meeting personal computer organization
active in the Greater St. Louis Area.
You are invited to attend this next ONLINE session, in lieu of any
regular physical face-to-face meeting. Further instructions below.
* ONLINE Sessions
* NO PHYSICAL MEETINGS until further notice.
* ONLINE session will use ZOOM remote video service 4 December 2025.
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
You do not have to have a microphone and webcamera to participate. You
can just chat, listen and watch using a Chrome based browser. We suggest
that you clear browser cache and cookies before starting any session.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
RECOMMENDED CLIENT TESTING:
We will open the remote session by about 6:00 PM, Central Standard Time.
Join early to test your controls, hearing (sound), video screen sharing
and microphone (speaking). You might be muted on entry.
During this half hour test period others may be able to help you.
Joining without ear buds, earphones or headset can result in a feedback
loop with a builtin laptop microphone. Using at least earbuds is highly
recommended. Wired Ethernet is always better than WiFi connectivity.
If you do not take the time and make the effort to get your connection
working correctly, you may be very disruptive. Annoying disruptions
may cause you to be kicked off the session.
Try dropping your connection and rejoin. That sometimes fixes issues;
but, do so slowly, as granting access to your microphone and camera too
quickly is the current main problem. Also, there are often sound
settings in different browsers that may need to be changed.
======================================================================
WHEN YOU ENTER THIS ONLINE SESSION:
6:00 PM Join early.
Please set your identity to show first name and last name. Instead of
full last name you could just follow first name with an initial. We
do prefer that you use your full last name.
Please hold you questions until after start of the meeting.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
6:30 PM Start of meeting.
Anybody joining after 6:30pm that experiences issues with controls,
hearing, screen sharing or speaking should only use chat room to ask
questions or make comments. Disconnecting and reconnecting usually
fixes issues from an initial problem session.
All may be muted at this point. You will have to unmute yourself in
order to speak. You can ask questions and make comments in chat room.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
ORDER OF EVENTS:
First some simple introductions, administrative minutia, announcements,
and then you can Call-For-Help during our Questions-and-Answers period.
Sometimes we may watch a video or have a slide show presentation,
after which there will be general discussions that usually lead to
additional topics.
Sometimes, there can be a live demonstration of a Linux distribution
(distro) installation, updating, changes, features and applications.
$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
TOPICS:
We usually hold a Hardware and Software Configuration Workshop when
nothing else more interesting comes up, or when there is no other
event or activity scheduled. This is an open free format workshop.
In this workshop we usually assess, configure, examine, fix, install,
repair, and troubleshoot difficult hardware and software configuration
problems for Linux newcomers. Problems with other operating systems and
hardware are also frequently fixed.
