Okay, ... for meeting announcement and web link(s), etc.
Hopefully what I've included below can be used quite directly (I also
include suggested subject for the announcement e-mail). Anyway,
hopefully someone can grab these tasks and do them fairly soon:
* send e-mail to balug-admin-balug.org(a)lists.balug.org that you will
send the announcement to balug-announce-balug.org(a)lists.balug.org
(that way we hopefully avoid multiple folks sending the same
announcement to balug-announce-balug.org(a)lists.balug.org)
* check the balug-admin-balug.org(a)lists.balug.org archives that you're
first to claim the above task (avoid race conditions)
* send the item out to balug-announce-balug.org(a)lists.balug.org
* once the item has been sent to
balug-announce-balug.org(a)lists.balug.org and appears in the archives,
create link(s) where appropriate (key references to the presentation)
on the http://www.balug.org/ page to the archived
balug-announce-balug.org(a)lists.balug.org announcement.

Subject:
BALUG May 17th presentation: LVM (Logical Volume Manager)
========================================================================
For the BALUG May 17th meeting, we will feature a presentation on
Logical Volume Manager (LVM) on LINUX by Michael Paoli.
BALUG and meeting general information (location, time, dinner cost,
etc.) can be found on the BALUG web site:
http://www.balug.org/
About Logical Volume Manager (LVM) and the presentation:
LVM allows for rather powerful and flexible management of hard drive
space. Rather than mostly having to deal with physical disks and
partitions, with LVM, one creates logical volumes, which can then be
used to contain filesystems or other data.
With logical volumes, one can relocate and resize logical volumes
while the data they contain is in use, and in general, without regard to
partition boundaries or disk sizes - as logical volumes can also span
multiple disks. This can make LVM a very power tool, for example
allowing one to:
* grow a filesystem while it's in use (if the filesystem type supports
growing it on-line)
* relocate in-use data (filesystem or whatever) to different physical
device or type of storage (for example, take a filesystem that is in
use and move it between different types of storage (e.g. among
non-RAID, RAID-5, RAID-1 or RAID-0+1 devices))
* more efficiently manage multiple filesystems on systems from those
with large numbers of disk storage arrays through those with as little
as a single hard drive
The presentation also promises to include a live demonstration of use of
LVM on LINUX, and also a bit of information about volume management
software in general on LINUX and UNIX platforms.
About Michael Paoli, our presenter for this event:
Michael Paoli has been doing UNIX systems administration for well over a
decade, has been using volume management software for about 9 years, has
been using doing LINUX systems administration for almost 7 years, and
has been using LVM on LINUX for about 2 years.
========================================================================
Wouldn't it be more appropriate (presuming it's feasible) to have a
"Beta" test area, on the same system, but, for example, using a
different port (e.g.:
http://www.balug.org:8080/
)
Key advantages:
one could test on the same system, and when things were found to be
sufficiently "better", they could be migrated from test ("Beta") to
"Production" (primary web site area and related URLs).
The process could be repeated as necessary to make incremental
improvements (and possibly even rather to quite large changes too).
Avoids most of the issues of having to shift between different systems and
issues of accounting for inherent differences between systems (e.g. hardware).
Isn't it also more appropriate for most of these discussions to be on
balug-admin-balug.org(a)lists.balug.org
rather than
balug-talk-balug.org(a)lists.balug.org
... after all, I'd think most subscribers to balug-talk probably aren't
so interested in these administrivia e-mails being on balug-talk,
particularly if they aren't fairly interesting/topical in a general
LINUX or BALUG (as in meetings, presentation, general discussions of
things LINUX and/or BALUG) context.

And yes, I'm confirming for the presentation for the BALUG 2005-05-17 meeting.
For the web site ... hmmmm, might first want to correct the presently
self-contradictory text (or whatever/however it was generated):
"The next meeting is today (Tuesday, May 17th) at 7pm"
Anyway, for at least a short(?) little blurb to update the web site, at
the moment, you can add this on there (or if this is way too long, see
the shorter alternative version further below):
"
For our May 17th meeting, we will have a presentation by Michael Paoli
on Logical Volume Manager (LVM) on LINUX. LVM allows for rather
powerful and flexible management of hard drive space. Rather than
mostly having to deal with physical disks and partitions, with LVM, one
creates logical volumes, which can then be used to contain filesystems
or other data. Unlike physical hard drives or partitions, however,
logical volumes can be relocated - including to other physical disks -
while the data is in use, and logical volumes can also be resized,
again, while their data is in use (provided whatever is using the data
can handle that - e.g. this can be very powerful for filesystem types
that can be grown with the filesystem mounted). Also, unlike
partitions on physical hard drives, when one grows a logical volume,
one generally only needs available space in the volume group (which is
composed of whole disks devices and/or partitions), and avoids all the
typical issues of resizing a partition (with partitions, one needs
contiguous available space after a partition to grow a partition). One
can also span multiple physical disks with a logical volume, and thus
have filesystems that are larger than the physical disk size. These
are some of LVM's powerful capabilities. The meeting presentation also
promises to include live demonstration of some of LVM's capabilities.
"
Anyway, ... that should do for a, ... uhm, ... "short" blurb on the web
site. If it's quite too big to be feasible to go there, perhaps
alternatively, this would do:

I'll also put together a bit more polished text that can be used for
BALUG-announce, etc. Expect that within a week (holler if you need it
sooner).

I'll bring laptop for the 2004-04-19 meeting.
If we have there whatever we need to hook it up for video/projector,
I should be set to run some tests - checking on optimal resolution for
whatever we'd be using for presentation. If that works reasonably well,
I could then put together presentation materials for 2004-05-17 meeting
(or a later date if there's something else we'd rather do for the
2004-05-17 meeting). That would also allow us to know what resolution(s)
are optimal for our setup, so we could pass that information on along to
future presenters and potential presenters.
For video output ports, my laptop has:
VGA (SXGA+)
SVHS (I've not tested that, and not planning to anytime soon)
DVI - but only via docking station (which I haven't obtained)
Anyway, VGA type output is probably least common denominator in terms of what
most folks coming in with a laptop (or other computer) would have for doing
a presentation, so it's probably most useful to test against that anyway.
