I've actually looked through the howto but am still unable to determine
how to actually create a lvm system. I've recompiled my kernel to
have the devive mapper as a module and modprobe'ed it.
When I try to do vgscan it states that the kernel modules are not loaded.
Please help.

Can I do an "upgrade" to FC2 test3?
by Gene Heskett
Basicly I don't want to loose all my passwords and such in the mozilla
cache. Can this be done, and if so, how?
Otherwise, I have amanda backups, what do I recover after doing it
fresh?

Monitor Trouble
by Brane Lj
I installed Fedora Core 1 and as usual the setup
didn't detect my monitor properly even though it is in
the list (Hansol 500A). I choose the proper monitor
and continued the installation (this worked on
previous versions of RH).
After i installed the OS and booted it for the first
time somewhere right after starting x my monitor
turned itself off. I'm guessing the resolution set is
not supported by my monitor. I went and edited the
/etc/X11/XF86Config file - horizontal and vertical
frequencies and resolution but that didn't help.
Lastly I used the Redhat-config-x86free (forgot the
right name) with the --reconfigure switch and i
recieved this error:
xconf.py :Fatal IO error2 (connection reset by peer)
on x server :17.0
The graphics card was detected properly - Radeon7000
For the monitor i recieved some bogus values...
I even reinstalled the whole lot and used a standard
800x600 monitor but no luck with that either.
Does anyone know what else I could try beside buying a
new monitor :D
thanks

Fedora and threading limit
by Guolin Cheng
Just got a problem on Fedora Core 1 box, I can only open 256 threads per
process. But on my former Redhat 8.0, I can open 1533 threads per
process. From post
http://www.redhat.com/archives/fedora-list/2003-December/msg04136.html
<http://www.redhat.com/archives/fedora-list/2003-December/msg04136.html>
, I still can not quite understand, Since I can only use 2GB stack
space. (256*8MB). Not 3GB.
The source of the thread-testing C file is from website
http://www.linuxquestions.org/questions/showthread.php?s=&threadid=17368
0.
Any other easy ways to change system-wide threading limit? At least from
Fedora Core 1's 256 to Redhat 8.0's 1533? Thanks A lot.

Problem connecting to Router and the WEB with madwifi
by Matthew Paulosky
I have a Linksys WRT54G router and a Netgear WG311 pci card. This setup
works very well with XP Pro but I am having problems in my Fedora Core 1
kernel-2.4.22-1.2174.nptl system. I installed the
kernel-madwifi-0.0.20040107-1_2.4.22_1.2174.nptl.rhfc1.i686.rpm from the
WIKI site. When the interface is up I can ping the card but not the Router.
Also I am unable to access the Router through the web interface. I know
that it will work because I got it to work once but don't have a clue how
and don't know what I did to loose it. Can anyone point me in the right
direction to get this up and running?
hwconf has the following listing for the wifi card:
class: NETWORK
bus: PCI

device: eth0
driver: ath_pci

Yes.. Time cosuming but if it's only 1 PC/drive. Bearable.
I used the systemrescuecd,booted off it, used partimage to save the
pastition to samba share. Changed the HD, partition it using qtparted
and then restored the partitions.
Restored the MBR and stuffs.

Alexander, I apologize, I certainly did not mean to respond that way. I
should stay off the computer that early in the morning.
I was trying to respond to the thread titled: Re: OpenOffice.org Calc

I am running version 1.1.0 and all dates including "4/11" are converted

Ah.. Yes.. IIRC, when I was re-reading and re-reading the ADSL
bandwidth limiting howto, the author did mention about shaping
downstream bandwidth using the TCP window size.
He also noted that there isn't any OSS software that's available
to do that. If anyone has any idea, i bet a lot of ppl would be
interested.
