Hardware upgrade -> Volume Group "VolGroup00" not found.
by Richard Shaw
This is the second time this has happened to me. The first time was
after a hardware upgrade on the computer I'm using right now, however,
it was an F8 system so instead of preupgrade I decided a fresh install
was in order, no big deal.
This time it's with my Myth Box running F10 and if I don't fix this
quickly the wife is going to kill me. Why does a hardware change (new
MB) cause this problem? Shouldn't it be able to find the volume group
regardless?
In my previous situation a livecd could find the volume group but the
installed system could not and I suspect the same will happen this
time but I am creating a livecd just to be sure.
Any troubleshooting ideas?
Thanks,
Richard

restore device?
by Tom Horsley
Is there some way I can convince fedora I'm never going
to suspend the system and it shouldn't look for the "restore
device" in some swap partition?
I'm in the process of genning my gazillion linux system and
I share the same swap partition between all of them and many
installers insist on reformatting swap, so the UUID has changed
many many times now, and rebooting into my main fedora system
always wastes time desperately trying to find that UUID :-).

System not booting after yum updates
by Craig Preston
After using my F10 system the other day, it automatically downloaded a bunch
a new updates and installed them. When I came back the next day to use the
system it will not boot now. After the grub screen it goes to start loading
and then displays the following error -
/bin/lvm error while loading shared libraries libreadline.so.5 cannot open
shared object file: no such file or directory
unable to access resume device (/dev/volgroup00/logvol01)
mount : could not find filesystem 'dev/root'
In my grub menu i still have the previous kernel listed and I can boot into
single user mode with it, but not the regular boot.
It seems strange to have just stopped working without me changing any system
settings. Only a week or so earlier I installed the livna Nvidia drivers, I
don't know if they have corrupted anything??
Any help would be great
Cheers

How to set up kermel parameters in sysctl.conf?
by (David) Ming Xia
Hi, All.
Does any body know any information about configuration of kernel parameters in sysctl.conf, especially, how to calculate kernel.shmmax and kernel.shmall?
I recently install IBM DB2 9.5 onto FC 10, and I got error message on my connecting to database. The error message is 'SQL1084C Shared memory segments cannot be allocated. SQLSTATE=57019'. This means I need to reconfigure /etc/sysctl.conf to change the size of the shared memory.
To figure out how to set the kernel parameters, I checked online and found many different stories.
1. I followed IBM document at http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp?topic=/com... My Power Edge has four GB, as specified in IBM document, we should use physical memory for kermel.shmmax, so I set:
kernel.shmmax=4294967296
kernel.shmall=943718 (4GB * 90% * 1024 * 1024 / 4)
But then after I invoked sysctl -p, and then ipcs -l, I got max seg size (kbytes) = 0. It did not work out.
I later set it as:
kernel.sem=250 25600 32 1024
kernel.shmmax=1073741824
kernel.shmall=1073741824
kernel.msgmax=65535
kernel.msgmnb=65535
kernel.msgmni=1024
and actually I got
# ipcs -l
------ Shared Memory Limits --------
max number of segments = 4096
max seg size (kbytes) = 1048576
max total shared memory (kbytes) = 4294967296 ( 4 GB!)
min seg size (bytes) = 1
------ Semaphore Limits --------
max number of arrays = 1024
max semaphores per array = 250
max semaphores system wide = 25600
max ops per semop call = 32
semaphore max value = 32767
------ Messages: Limits --------
max queues system wide = 1024
max size of message (bytes) = 65535
default max size of queue (bytes) = 65535
Redhat gave a example for Oracle, http://www.redhat.com/docs/manuals/csgfs/oracle-guide/s1-ora-nodes.html. But they did not tell how they got these values, for how much physical memory.
Some other people told kernel.shmmax should be half of the RAM, like http://freekdhooge.wordpress.com/2007/11/11/linux-unix-kernel-parameters/.
So, where can I got some solid, authoritative information on this, especially from Redhat?
I would truly appreciate your advices.
Thank you very much.

fc10 disklessrc file: where is it???
by Reg Clemens
I am trying to get a diskless client running under fedora10.
Under previous Fedora's there was a 'disklessrc' script that got
appended to one of the rc files during startup, and for my
setup, I had to modify it.
In the current (fedora10) setup, I no longer see this file, but
the functionality must still be there somewhere, and you see the
name 'dislkessrc' go by during the boot.
SO, where has this file or its functionality gone?
Ive scanned file system looking for it, and dont find it.
Im about to scan all the files in the diskless file system, but
any help would be appreciated.

Text editor won't let me edit conf files. How do I?
by David Ward
I'm not good at the command line (Just past newbie). I try to edit .conf files to set up samba but the text editor tells me I don't have permission. All of the system admin functions ask me for authorization and then let me do whatever but not the text editor. I have added the gdm group to the directories the gnome docs told me to (/run/gdm). I have added the gdm group to my user group profile. How can I get a GUI text editor to let me edit .conf files?
Thanks up front for any replies.
RHFC-10 out of the box on a Dell D600
Dave.

Feedback on topics for IRC Classroom sessions
by "G"
Hi Everyone
1.Creating a Virtual Router environment using Fedora and UML.
2. Creating a filesystem using busybox and using it with QEMU on fedora
3. Introduction to Netlink Sockets- What are they ?
4. Netlink Sockets Part 2
5. The UML Switch
I plan to take these sessions from April and i have already updated the
first list at https://fedoraproject.org/wiki/Classroom .
I am also planning to take sessions on areas like Security (IPSec, OpenSwan
etc) and Routing (BGP,OSPF,etc) Switching (VLAN, RSTP,MSTP), MPLS etc.
Can you let me know if anyone interested to attend these. If they are i
could take these as these are hot technologies and you could probably think
what connection does it have with Fedora. In a sense yes it has, Routing you
could take quagga routing suite and i could give a demo on how to setup
routing environment using quagga on fedora. and how to setup BGP session and
if its MPLS you could still do the same with MPLS packages available for
fedora and then patching the kernel too. and OpenSwan is very famous with
IPsec
Do let me know your suggestions and comments.
Thanks,
Cheers,
Balaji

Did you have a KWorld TV capture? it works for my under F8 with saa7134 driver, setting the correct card and tunner option and then loading
saa7134-alsa module for audio. Search google for saa7134 and you will find good guides in v4linux site.
