Updatedb in xen mode
by Luc MAIGNAN
Hi,
on a fedora 6, I've setup a guest OS (FC6 of course). On the guest OS,
when I do an 'updatedb', the system seems to be freezed and takes 99%
CPU. It hasn't finish after 1h30... (nothing has been installed after
the OS)
Any help would be appreciated

FC6 (&7) netboot
by Stefan van der Eijk
Hi,
I'm trying to get FC6 working on a diskless system. I hope this is the
correct list to discuss this topic, if not please ignore this message.
As I mentioned, I'm trying to get FC6 to work in a diskless system. To
do this I first installed FC6 in a VMware (with disk). I'm using that
as the "example" system.
I'm following the instructions provided in the documentation of the
system-config-netboot-0.1.41-1.FC6 package. After rsyncing over the
files to the NFS server, setting up DHCP and TFTP servers it's time
for the first attempt. The diskless client is a vmware, confgured to
boot over the network (PXE).
With the first attempt, the system stops with the following error:
"Mounting rot filesystem: /nfsroots/fc6-diskless/root from 192.168.254.254
mount: wrong fs type, bad option, bad superblock on
192.168.254.254:/nfsroots/fc6-diskless/root,
missing codepage r other error
In some cases useful info is found in syslog - try dmesg | tail or
so."
For screenshot see: http://eijk.homelinux.org/~stefan/fc-diskless/1.jpg
As mentioned in
http://www.mythtv.org/wiki/index.php/Diskless_Frontend#Redhat_and_Fedora_...
/sbin/mount.nfs is missing in the initrd.img. This patch adds it
(although I'm not sure if mount.nfs4 should be added too):

if [ ! -e $ROOT/sbin/busybox.anaconda ]; then
2nd attempt ended with it complaining that it couldn't pivot_root.
Seems that /.oldroot directory isn't created. For screenshot see:
http://eijk.homelinux.org/~stefan/fc-diskless/2.jpg
After making that directory it also complains that /.snapshot isn't
made either. Starting udev takes ages,

I didn't wait for it to finish, just made the directory on the NFS
server and reset the vmware.

After re-reading the .html pages in
/usr/share/doc/system-config-netboot-0.1.41/ I followed the
instructions to create a client. Changed the pxe config to reflect
this.
label fc6
KERNEL vmlinuz
APPEND initrd=initrd.img root=/dev/ram0 init=disklessrc
NFSROOT=192.168.254.254:/nfsroots/fc6-diskless ramdisk_size=19102
ETHERNET=eth0 SNAPSHOT=fc6-diskless
resulting in this: http://eijk.homelinux.org/~stefan/fc-diskless/5.jpg
added "ramdisk_blocksize=1024", from
http://www.mythtv.org/wiki/index.php/Diskless_Frontend#Redhat_and_Fedora_...
The end result is a FC6 diskless client that hangs on starting udev.

I'm wondering what I've missed in the documentation and what I'm doing
wrong. I feel that I'm already correcting too many things myself -->
this stuff should be made in a way that it just works and is trivial
to set up. As the package version/release is still the same in
rawhide, I guess this same package is going to be shipped with FC7.
What would be the best way to move forward? Shall I start with filing
some bugreports? Or is this not the right time to do so (freeze for
fc7)?
with kind regards,

FC6 Combo drive doesn't work with DVD's
by Antonio M
I see that also after recent updates in FC6 my combo drive (that is
detected as QSI CD-RW/DVD-ROM SBW242U and device /dev/hdc) works with
CD/CD-R/CD-RW but when I insert a DVD with data/files nothing happens.
I suppose that DVD should show up on my dsktop.....on the other hand I
can play a DVD with Xine even if it is not automatically mounted.
Any idea???

Switching to libata drivers
by John Wendel
I'd like to switch my PATA drives to use the new libata drivers
instead of the old ide drivers. Can someone point me to a howto or
other document that explains what I need to change.

FC6 error at start--vdevd add_to_rules unknow_key ...
by L
Hi
When vdevd starts at booting FC6, there is error messenge as follows,
vdevd
add_to_rules[403] unknown_key ATTRS{idProduct}
It repeated a few rows. What does it mean?
And, this messenge flashs very quick, It took about 5 reboots to gather this
error messenge. The 2nd question is how to capture the error messenge at the
beginning of system boot?
Thanks

Smolt vs. dmidecode
by Sean Bruno
Just a curious point.
I noted that my smolt profile doesn't indicate my system's motherboard
model/revision information. I guess ASUS just never got around to
filling in the bits at whatever location smolt is looking.
UUID: 2f04459f-c147-4b96-b912-24b8534bc6e2
OS: Fedora Core release 6 (Zod)
Default run level: 5
Language: en_US.UTF-8
Platform: x86_64
BogoMIPS: 2010.05

Number of CPUs: 2
CPU Speed: 2000
System Memory: 5950
System Swap: 1983
Vendor: System manufacturer
System: System Product Name System Version
It also seems that dmidecode pulls that information, but is is able to
get the mobo model/revision info from the BIOS at a different location:
# dmidecode 2.7
SMBIOS 2.3 present.
56 structures occupying 1766 bytes.
Table at 0x000F0000.
Handle 0x0000, DMI type 0, 20 bytes.
BIOS Information
Vendor: Phoenix Technologies, LTD
Version: ASUS K8N-DL ACPI BIOS Revision 1008
Release Date: 02/17/2006
Handle 0x0001, DMI type 1, 25 bytes.

Product Name: System Product Name
Version: System Version
Serial Number: System Serial Number
UUID: 50ECB49C-06A4-D911-B7D5-E9686682C17E
Any chance that smolt can be modified in the same way? Just a thought.
