Btw, FF nightly now has a tracking protection feature that does the "no
tracking" job of many of the privacy add-ons like Privacy Badger,
Ghostery, Disconnect Me, etc.  They even have a menu option, both are
still hidden inside about:config though.

Again, FF now has something called electrolysis (e10s), which makes it
multi-threaded.  Not sure which versions of FF has the feature.  I find
it is quite effective, but maybe a bit buggy.

Not sure what relevance that has to CPU usage.

Well, since Fedora doesn't distribute "nightly" and that e10s option doesn't 
exist on the fedora released version I don't know what relevance it has to the 
discussion.

As I understood the topic was unusual CPU loads.  Since you mentioned
adverts (considering they are often responsible for strange CPU loads),
I thought I mention a feature FF will have in the future.  Tests by devs
suggest the feature improves on CPU load and page load times
significantly.

Again, I thought this was relevant for a discussion of CPU loads,
specially after you pointed out the single-threaded nature of FF.  I
just didn't know if the Fedora supplied version already has it.

 The only "issue" I saw is that playing a video from youtube is choppy even 
 though you can see from the progress bar that the video itself has been

I see.  Well, looking at the WiKi 
(https://wiki.mozilla.org/Electrolysis/Roadmap) for this it seems it is nowhere 
near being ready for prime time and certainly not something Fedora releases.

What I was addressing in my earlier response was my current experience with FF 
in its present form as released by Fedora sans any extensions.   Personally I'm 
not looking for how future improvements may help since I don't expect I'll 
switching back to using it.  :-) :-)

dnf autoremove -- removes explicitly installed thunderbird

[A.J. Bonnema]

Hey all,

Anyone noticed that after successfully installing thunderbird with "dnf 
install thunderbird" the statement "dnf autoremove" selects thunderbird 
for removal?


I would like hear if anyone else has this problem.

Regards, Guus.

I sometimes go beyond 300 tabs, approaching 500.

This abandoned extension is incredibly useful:

https://www.dropbox.com/s/61ovoc4hzgtm0qf/Suspend-background-tabs-master.xpi?dl=0

Javascript is disabled for all background tabs, so they won't use CPU time 
anymore.

I guess I don't quite understand the usefulness of having so many open tabs.  
Feels like a cluttered desk to me.  Maybe it has something to do with my short 
term memory not being what it used to be.  Now, where are my keys?  :-)

Acer C720 Support

[Zach Villers]

Sorry if I am posting to the wrong list. I'm wondering what needs to happen to 
get Anaconda to work on a Chromebook laptop with F22 and beyond?

I have been trying to install Fedora on my Acer C720 Chromebook. Rawhide, F22, 
and F21 .iso's written to a usb drive via dd will not get past the grub splash 
screen. I've tried changing the boot parameters, to no avail. The C720 had a 
working Xubuntu install on it, so I know I have set the machine's bios up 
properly. I have been able to find this information regarding a possible 
syslinux issue; http://www.syslinux.org/archives/2015-February/023209.html 

I was able to install with a Fedora 20 netinstall image using these 
instructions; 
https://onemoretech.wordpress.com/2014/03/28/booting-the-acer-c720-with-fedora-20-live/
I just pointed Anaconda to an F22 workstation mirror.

There are reports for various Chromebook issues on bugzilla; 
https://bugzilla.redhat.com/buglist.cgi?quicksearch=chromebook so I know that 
people have been able to install. I would be willing to test any patches that 
can be provided, but when I tried the patch of syslinux suggested in the 
syslinux mailing list, I still could not get the iso i created with (what I 
thought was the patched version of syslinux) to work. TIA and apologies for the 
ramble.

What do you get for

  rpm -qa elfutils\*

and

  dnf list elfutils\*
 ( or: yum list elfutils\* )

?

Typically (normally!), the i686 and x86_64 builds of a multilib package
are made available in the x86_64 repo at the same time. The only chance
to get a version mismatch as above is when you're assigned to a broken
mirror, or if your installation is broken by duplicate packages, or if
you somehow managed to upgrade only either arch (causing a version mismatch
to begin with).

What is the case for you needs to be examined.

[Joe Zeff]

Subject: This is what I was talking about

Jerry, earlier this year I wrote you a letter about how the Air Force 
could make better use of air supremacy.  (Another of your readers 
responded, accusing me of "victory through air power.)  Here's an 
article you may not have seen showing us doing exactly the type of thing 
I was advocating: 
http://www.military.com/daily-news/2015/08/02/us-led-raids-destroy-isis-bridges-on-iraq-syria-border.html?ESRC=navy.nl 
 You drop the bridges and it makes it harder and slower for ISIS to get 
troops, supplies and equipment to the front where they're needed and 
that makes it easier for our "boots on the ground" to do their job.  I 
do have to ask, though, what took them so long?

Inactive raid1 partition failure

[Alex]

Hi,
I have a fedora21 system with three md RAID1 arrays. I had used this
system to temporarily access an external array connected to an LSI
controller in the system. So I inserted the LSI controller, accessed
the data on the disks connected to it, and removed the controller from
the system.

Now, all three md RAID arrays are in some type of degraded state:

# cat /proc/mdstat
Personalities : [raid1]
md2 : inactive sdb1[1](S) sdc1[4](S)
  1953519616 blocks super 1.2

md0 : active raid1 sda1[0]
  511988 blocks super 1.0 [2/1] [U_]

md1 : active raid1 sda2[0]
  237566840 blocks super 1.2 [2/1] [U_]
  bitmap: 2/2 pages [8KB], 65536KB chunk

Thankfully the system boots. The inactive array, md2, is connected to
/var/backup, so I just commented it out of /etc/fstab to get the
system to boot.

It appears the devices were somehow impacted by the LSI controller,
and now the partitions/devices have been reordered.

How do I realign these slices to rebuild the array?

Thanks,
Alex

No Audio in F22

[Stephen Morris]

Hi,
I have installed F22 from scratch via the live dvd and even though 
I have pulseaudio installed and configured via the multimedia interface 
in system settings in KDE I am unable to get F22 to play any sounds at 
all, plus I don't have a speaker icon in the system tray.
I had no issues with audio in F21 on the same hardware, nor do I 
have any issues on this hardware under windows.
I am using the onboard 7.1 surround sound audio chip on the 
motherboard.
Does anyone have any ideas on what I can look at to work out why 
there is no sound?


regards,
Steve

Re: Inactive raid1 partition failure

[Chris Murphy]

It looks like a device is completely missing?

blkid > blkid.txt

Then for each md device UUID pair (the md UUID will show up twice in
blkid for each of the three arrays):

mdadm -E>> mdXraidstats.txt

Where X=the md device from mdstat. That way you get the superblock
from each device making up each array into an array specific text
file. They can go all in one file, but it's easier to keep things
separate.

journalctl -b -l -o short-monotonic > journal.txt
/etc/mdadm/mdadm.conf

Post those files somewhere and the URL here.

The journal should say why it wasn't assembled. But the main thing is
you should get copies of all device superblocks before you do anything
else, especially reading around the internet where often people get
the idea that they need to use -C to recreate an array which
obliterates the old metadata and almost invariably kills their data.

It looks like you haven't provided the SIM's PIN under F22:

I don't use such a card (I have a Verizon hotspot that I can

Re: Inactive raid1 partition failure

[Sam Varshavchik]

Alex writes:


Hi,
I have a fedora21 system with three md RAID1 arrays. I had used this
system to temporarily access an external array connected to an LSI
controller in the system. So I inserted the LSI controller, accessed
the data on the disks connected to it, and removed the controller from
the system.

Now, all three md RAID arrays are in some type of degraded state:

# cat /proc/mdstat
Personalities : [raid1]
md2 : inactive sdb1[1](S) sdc1[4](S)
  1953519616 blocks super 1.2

md0 : active raid1 sda1[0]
  511988 blocks super 1.0 [2/1] [U_]

md1 : active raid1 sda2[0]
  237566840 blocks super 1.2 [2/1] [U_]
  bitmap: 2/2 pages [8KB], 65536KB chunk

Thankfully the system boots. The inactive array, md2, is connected to
/var/backup, so I just commented it out of /etc/fstab to get the
system to boot.

It appears the devices were somehow impacted by the LSI controller,
and now the partitions/devices have been reordered.

How do I realign these slices to rebuild the array?


The first step is to see what

mdadm --detail /dev/md0

says. Repeat for md1, et al…

Each one of your arrays is either missing a drive, or the other drive is  
marked as faulty.


If it's missing, use --add to add each drive to it's array. If mdadm says  
the drive has failed, try to --remove, then --add it back in.

Thanks so much for your help. In the process of disconnecting the LSI
controller and power cable connected to the disks, somehow the power
cable at the power supply side was loose for one of the other system
drives. Using these commands, I was able to figure out there really
was a device physically missing.

I panicked a bit, and didn't want to do something stupid (like mdadm
-C) before passing it by at least one other person. After connecting
the power cable, I was able to easily "mdadm --add" the drives back
and rebuild both degraded arrays. The /var/backup partition came up
automatically.

Another great mdadm command to know is --details.

Thanks again guys,
Alex

Re: Acer C720 Chromebook

Are you running the stock BIOS? I flashed johnlewis's ROM and can successfully 
boot F22 media. I initially had to do F20->F21->F22. Flashed the ROM, ran 
Debian for a while, and then 
went back to a minimal F22 install. I don't recall having any issues booting 
Fedora media after flashing the BIOS.

amavis stopped logging to maillog after upgrade

[Alex]

Hi,
I recently performed an upgrade from fedora20 to fedora21, and now
amavisd-new no longer logs to /var/log/maillog (or anywhere else that
I can find.) The /etc/amavisd.conf file hasn't changed. I've also made
sure rsyslog is still running, and is receiving logging info from
postfix.

# grep log /etc/amavisd/amavisd.conf
$log_level = 2;  # verbosity 0..5, -d
$log_recip_templ = undef;# disable by-recipient level-0 log entries
$DO_SYSLOG = 1;  # log via syslogd (preferred)
$syslog_facility = 'mail';   # Syslog facility as a string
$syslog_priority = 'debug';  # Syslog base (minimal) priority as a string,

# egrep -v '^$|^#' /etc/rsyslog.conf
$ModLoad imuxsock # provides support for local system logging (e.g.
via logger command)
$ModLoad imklog   # provides kernel logging support (previously done by rklogd)
$SystemLogRateLimitInterval 0
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
$IncludeConfig /etc/rsyslog.d/*.conf
kern.none /dev/console
kern.*  /var/log/kern.log
*.info;mail.none;authpriv.none;cron.none/var/log/messages
authpriv.*  /var/log/secure
mail.*  -/var/log/maillog
cron.*  /var/log/cron
*.emerg *
uucp,news.crit  /var/log/spooler
local7.*/var/log/boot.log

I don't understand if this is a journalctl error or not. The logs are
going to the standard journalctl log. There is also no
/var/log/amavisd.log file present.

Thanks for any ideas.
Alex

I definitely suggest you make a backup of each device superblock and
distribute it somewhere safe in the unlikely event two devices in a
mirrored array stop cooperating. The superblocks do come in handy from
time to time when they can't be acquired once problems happen.

The other thing is, if you're panicked, it kinda suggests no recent
backup. I can't tell you how many sad panda faces I see on many lists,
including the linux-raid@ list (all things RAID on Linux but mainly
md/mdadm) and it's like, really no backup? The brutal response is, if
you don't have a backup the data isn't important.

Great!

Yeah it's easy to get -D and -E confused. -D is pointed at the running
array and -E is pointed at devices. But they're functional
equivalents.

Do you have any suggestions on how to do this?

I do have a backup, but it would be a pain to rebuild everything. It
would be a major inconvenience. No one really ever wants to go through
that.

mdadm -E for each device, and point it to a file using >> - for the

Re: Re: Acer C720 Chromebook

Yes, I am running the stock SeaBIOS. I did use a F20 netinstall iso and just 
changed the mirror to an F22 source. 

I guess my question is, and maybe this isn't the place for it, why can I 
install OpenBSD, DragonFlyBSD, Ubuntu, Debian, Gentoo, and Arch on the stock 
firmware, but not Anaconda? Is it the syslinux version I referenced or 
something else?
