Fixing a crashed disk
by SternData
I quite stupidly unplugged my computer today when my foot got tangled in
the power strip. On reboot, I was notified
Device: /dev/sda [SAT], 8 Offline uncorrectable sectors
Smartctl tells me the problem is at LBA 2014551336 (this is a 2TB disk).
Following the info here
http://kaivanov.blogspot.com/2010/09/fixing-disk-problems-under-linux-wit...
I'm not able to determine what file might be sitting on this block.
tune2fs -l /dev/sda5 |grep Block
Block count: 472552448
Block size: 4096
Blocks per group: 32768
[root@sds-desk-2 ~]# debugfs
debugfs 1.42.3 (14-May-2012)
debugfs: open /dev/sda5
debugfs: icheck 235992741
Block Inode number
235992741 8
debugfs: ncheck 8
Inode Pathname
This suggests that the problem is not in a currently extant file.
I'm now trying the suggestion of writing from /dev/zero to a file in
/home while in single users mode. Given that I have 1.5TB to fill,
this could take a while.
Here's the question: If I just reformat and restore /home from a
recent backup, will the disk automatically deal with the sectors
pending reallocation?

bc and built-in funcs
by JD
Hi all
I have:
$ rpm -q bc
bc-1.06.95-3.fc15.i686
I was searching the web for bc funs to calculate cube roots
and other arbitrary roots. Almost all of the func I found
assume that bc has the built-in funcs l and e which take
a numeric arg.
Yet my bc has no such funcs.
Is the version above broken?

No Music or Movies Play in F17 - Missing Gstreamer?....
by EGO-II.1
I have a Gateway T-6321 that I recently had to re-install Fedora Linux
v17 on. I've put just about everything that was on there from before
(Totem, Clementine...Thunderbird etc.) but when I try to play movies in
Totem or music in Clementine I get errors such as:
Clementine: - "Your GStreamer installation is missing a plugin."
Totem: - "A program requires additional plugins to decode this file:
The following plugins are required:
H.264 decoder
MPEG-4 AAC decoder
Do you want to search for these now?
My problem is when it searches for these it tells me they're already
installed? What is the solution for this kind of error? is there a file
I need? or a missing piece of this puzzle?
Thanx!

ABRT didn't detect segfaults of usb_modeswitch
by Clemens Eisserer
Hi,
Running updates-testing I noticed once my usb modem didn't work -
caused by usb_mdoeswitch segfaulting 3 times in a row:
Oct 29 18:37:27 localhost kernel: [ 23.740625]
usb_modeswitch_[1374]: segfault at 7fff0251aff8 ip 000000300087f434 sp

usb_modeswitch_[1515]: segfault at 7fffd8b8ae74 ip 0000003000874b06 sp

00007fff7eb4f000 error 6 in libc-2.15.so[3000800000+1ac000]
ABRT didn't detect those crashes. Is this due to a technical issue?
Is there any way to get the name of the function where usb_modeswitch
crashed in the above cases, so I can at least file a bug-report?
Thanks, Clemens

Fax to email gateway
by Gary Stainburn
Hi folks.
I'm looking to create a fax gateway, either fax to email or fax to program.
I've googled this but everything I've looked at it at least 5 years old. I was
wondering what people are using these days and what's good now.

Purge old eth1, add new nic as eth0
by Frank Murphy
How can I completly remove all remnants of an old eth1
Everytime I go to add a new nic it wants to call it eth1
I will be replacing the old nic with ano identical chipped card,
which it wants to call eth1
I would prefer eth0
F17 using system-config-network
I have through s-c-n removed all hardware nic,
also removeed ~/network-scripts/ifcfg-eth*
Keeps coming back,
Where else do I look.

With you there Doug. Having seen Windows 8, maybe Autodesk will do an
about face and return to UNIX/Linux as its primary platform.
Before hiring a contractor, I need to revise old hard copy drawings and
completely redo the electrical and lighting layers. The ability to build
a list of materials would be a real plus.

getting dumped to emergency console on boot
by Ian Malone
Anyone else seeing this? I'm getting dropped to emergency mode during
boot since my last F16 yum update. It included a kernel update, but
I'm not certain yet that it is the kernel, because it's not 100%
reproducible. Issuing a ^D gets me to GDM and the system appears to
work. At the console there are no particular messages (occasionally an
alsa warning), the only real clue I can find is this in dmesg:
[ 113.821947] systemd[1]: Job
dev-disk-by\x2duuid-87b66172\x2dcd62\x2d498a\x2da33b\x2d621948ce37ea.device/start

$ grep 87b6 /etc/fstab

Not sure how to further troubleshoot this.
That alsa warning, but doesn't seem relevant:

How can I prevent udevd from renaming eth0 to em1
by JD
I googled this and came across 2 purported
solutions, neither of which worked.
1. Uninstall package biosdevname and reboot.
That did not prevent udevd from renaming eth0 to em1.
2. Add the line
biosdevname=0
to /boot/grub2/grub.cfg
That did not work either.
Any other way to get around this renaming?
