F16 (gnome/default)- cpu usage 100%
by Nermin Celik
Hello,
I've just upgraded my computer from F12 to F16 (Gnome Desktop
Edition/Default). Although haven't played with F16 much, it looks quiet
impressive. Thank you for the developers and contributors.
Question:
Firstly, my computer is 3-4 years old, with 2 CPUs, built by a friend. I'm
not much of a hardware person hence can not give further details. Sorry.
Just looking at System Monitor > Resources > , it shows that CPU1 and CPU2
are 100% used, although l'm not running any programs. Hence it seems that
my computer hardware is not compatible with F16 (default). Do you agree?
I'll be using more computer mainly to write/run Perl programs, run
bioinformatics tools, create/edit images. Hence is it best to install F16
KDE Spin, F16 LXDE Spin, F16 Xfce Spin or F15?
Thank you in advance for your assistance.
Regards,
N

Implementing a "sometimes" RAID on a laptop. (eSATA, SSD, RAID 1)
by linux guy
I experienced a complete SSD failure this week on my laptop.
I've ordered a new Dell XPS 17 laptop which has an eSATA port.
Given the nature of the SSD failure I experienced, from now on I wish
to have my laptop running a RAID1 setup via the eSATA port when its
used on my desk. However, when its not used on my desk, I wish it to
function normally without the RAID functionality.
Question 1.
How does one set up a "sometimes" RAID ? Or would something like
rsync be better ? What happens the first time I plug my laptop into
the eSATA cable after being away from my desk ? What happens if there
is both new data and an error in existing data ? How does the RAID
software know the difference ?
Question 2.
Internally, my XPS17 has 2 hard drives. I will probably use an SSD
for the OS and a 750 GB 7200 RPM conventional drive for data.
How does one configure the single external eSATA RAID drive to back up
(mirror) the data for both internal drives ?
Question 3.
The OS drive will be an SSD which is faster than the eSATA RAID drive,
which will probably be a 7200 RPM 2TB+ conventional drive. Will this
limit the speed of the SSD to that of the eSATA drive or is buffering
employed to allow one to be faster than the other ?
Question 4.
Can only a portion of the eSATA RAID drive be allocated to the RAID
and the rest left to be mounted by the laptop for general access ?
Thanks !

File copy errors on EXT4 SSD but fsck says its clean ????
by linux guy
I am trying to do a full backup of my home directory on an SSD drive
with about 70 GB of content via a straight folder to folder copy in
Dolphin.
When I did the copy, the process reported a file could not be read. I
answered Skip and it continued. A short while later it reported
another file could not be read. I answered Auto Skip. Then I went
to bed.
When I woke it, it appeared that the process had completed, but that
only 69 of the 70 GB had been copied, ie there were a lot of
unreadable files.
I pulled the drive from the laptop and installed it into another
working system as a data drive.
The drive is formatted EXT4. It has 3 partitions, /boot, swap and /.
When I run fsck on it, it reports its clean.
[root@server me]# fsck /dev/sdb1
fsck from util-linux 2.20.1
e2fsck 1.41.14 (22-Dec-2010)
/boot: clean, 300/150600 files, 178166/610436 blocks
[root@server me]# fsck /dev/sdb2
fsck from util-linux 2.20.1
fsck: fsck.swap: not found
fsck: error 2 while executing fsck.swap for /dev/sdb2
[root@server me]# fsck /dev/sdb3
fsck from util-linux 2.20.1
e2fsck 1.41.14 (22-Dec-2010)
/: clean, 1063293/37126144 files, 29660166/37120190 blocks
I ran the process again and tried to nano the files that its reporting
it can't read. Nano can't open them either and they are not binary
files.
Where do I go from here ?
How would I best do a command line copy such that it doesn't stop at
the files it can't read and it creates a log of them ? (What does cp
--force do ?)
Thanks !

Trouble with Burning Video DVD's
by Charlie McVeigh
Not a Fedora problem exactly, but I am asking here anyways because there
are so many people smarter than me on this board. I am using Fedora 14
as I describe my situation below.
I created a photo sideshow using Imagination and rendered it as a .vob
file such that it is suitable for a video DVD. Using DeVeDe I built the
appropriate menu structure for the video DVD and generated an .iso file
ready for burning as a video DVD. Lastly I used K3b to burn the .iso
image to a DVD+R disk.
Here is were my problem begins – the video DVD will not play on every
device that I put it into. It plays fine on every computer in my house,
my son's Xbox, and a Sony DVD player connected to one of our TV's. It
does *not* play on a neighbors Mac Book Pro, but does play on their DVD
connected to the TV. When I go to another neighbor it does work on their
Mac Book but when playing on their DVD attached to the TV I get
“venetian blind” effect where the DVD is playing but I have stipes
across the screen like looking through a venetian blind.
I am pretty sure the problem is when I am rendering the .vob or creating
the .iso, but I simply don't see any options to tweak. What do I need to
do to get a video DVD that play reliably across many devices?

DVD ISO copy weirdness
by 夜神 岩男
I bought a new movie on DVD the other day for my kid (Christmas and
all...). I wanted to back it up because I've noticed a few of my older
DVDs don't play correctly anymore (blocky in spots or don't play period
but are studio cuts that used to work!).
Normally I just put a DVD in the drive, select "Copy disk..." and move
through the dialogue to save it to an .iso. Later I can either have the
computer or the player play it from anywhere in the house.
Simple.
But today this one is acting strangely. It is giving me a css key error,
which is weird, because this is not BlueRay or anything, and it works
just fine in the ancient for-TV DVD player, so its nothing new.
Beyond that, I can open the disk up and see the typical DVD directories:
{VIDEO,AUDIO}_TS
Looking in VIDEO_TS to see what's the matter, everything can be played
just fine. No CSS problems. The DVD works in Media Player, VLC, etc.
just fine. I can run each individual chapter segment as well. But the
total size of VIDEO_TS claims to be 46GB, about 10 times bigger than it
should be... and I'm not going to copy 46GB just to get a movie. It was
a good movie, but not THAT good.
Any ideas?

There is a way to determine things remotely, if you do some setup
beforehand.
Your two hard drives are otherwise (I presume) exactly alike.
Set them up similarly, *except* that both use all but a megabyte or so
(or one cylinder's worth of blocks). Make that little extra into a
partition on ONE of the disks.
You can then remotely use 'cat /proc/partitions' to show the attached
drives and partition sizes (or use 'sfdisk -uC -l').
The extra partition will denote which drive is being used as 'sda' or
'sdb'. This method is independent of the contents of the disk.
You may be able to re-size both of them in place although it might
require another site visit. I have NO idea if gparted can be made to
work remotely with vnc etc.

p21p1 is down after reboot
by Hiisi
Hi, list.
I've deleted NetworkManager and created
/etc/sysconfig/network-scripts/ifcfg-p21p1 with following content:
DEVICE=p21p1
TYPE=inet
ONBOOT=yes
BOOTPROTO=dhcp
#IPADDR=10.7.0.200
#NETMASK=255.255.255.0
#NETWORK=10.7.0.0
#BROADCAST=10.7.0.1
NAME=p21p1
BRIDGE=br0
Whenever I reboot this system p21p1 is down (I have first to ifconfig
up it and act with dhclient to it). What's the prob? What am I doing
wrong?
TIA

where is the config for dynamically added volumes in nautilus?
by Da Rock
I've googled for close to a week to resolve this. I know that inserting
a usb disk (depending on setup and version) causes a knock on effect by
calling dbus, hal, and maybe more depending. But *how* does nautilus (or
any other file manager system) find out that the disk is there and put
an icon in the sidebar ("places")?
I've checked bookmarks, GConf- nothing I can see anywhere tells me how
this is done. I figured there must be a GConf setting somewhere or
another backend that stores this otherwise there'd be too many lookups.
Surely it can't be polling for it through hal continuously?
Clues anyone?

A couple of repeatable ways to freeze-up Fedora..
by Linda McLeod
A couple of repeatable ways to freeze-up Fedora.. which is probably
related and linked to other unsolved problems in Fedora..
As F-14 is booting-up, plug-in 8 flash-drives (2 hubs) before the OS is
fully booted...
With Shotwell slideshow up at full screen, tap "next pix" button about
ten times...
Tell me.. When glitches are found, diagnosed, and solved, does the
solution fix other unexpected problems in other areas..?
