Re: Unable to blank dvd/rw media

I err'd when I wrote the above as I actually found 2 DVD's in the drawer and the one I 
used was an off-brand from "Melody Group" here in Taiwan and blanking worked.

The Philips brand DVD+RW does *not* support the "blank" option when using the 
dvd+rw-format tool...

[egreshko@meimei ~]$ dvd+rw-format -blank=full /dev/sr0
* BD/DVD±RW/-RAM format utility by , version 7.1.
* 4.7GB DVD+RW media detected.
- illegal command-line option for this media.


I found the dvd+rw-format man page quite readable (unlike some others) 
and helpful in explaining the difference between  DVD-RW and DVD+RW 
media with respect to blanking/formatting:



To blank a DVD-RW and put in the incremental sequential mode, run:
dvd+rw-format -blank=full /dev/dvd
...

-force[=full]
Perform formatting even if the medium is formatted already. This is not 
recommended for  BD-RE  and  DVD+RW media, since  they  need to be 
formatted only once. Use -format=full to perform full (lengthy) reformat 
in case of DVD-RAM ...

...

Note that DVD+RW re-formatting procedure does not substitute for 
blanking. If you want to nullify the media, e.g. for privacy reasons, do 
it explicitly with 'growisofs -Z /dev/dvd=/dev/zero'.

In my opinion you're going about this the wrong way (walk before you try to

pvcreate

[Patrick Dupre]

Hello,

Using fdisk I create a partition of 59Go (/dev/sdxy)
Then I do a pvcreate /dev/sdxy)
pvdisplay says:
/dev/sdb7" is a new physical volume of "38.00 GiB"

This probably results from a previous partitioning.

How can I clear this glitch?

Thank

Red Hat is big contributor to Gnome so Fedora is a Gnome-centered distro.
It supports other DEs but the default assumption is that you're using
Gnome. This is evident from a lot of the documentation as well the
packaging structure as you point out. That said, there's no problem using
another DE and a lot of us do so. We just put up with some the Gnome
components being more or less ever-present as long as they doesn't get in
the way. And of course having them means you can use Gnome-based apps such
as Evolution without having to put up with the weird desktop GUI.

It would be interesting to find out just what percentage of active users
are on each of the main DEs, but I can't think of a reliable way of doing
that i.e. one not subject to selection bias.

Consider giving more details first. It is confusing that you refer
to /dev/sdxy and /dev/sdb7.

Show the output of

  parted /dev/sdb p
  fdisk -l /dev/sdb
  pvs

Perhaps there will be some interesting details in there.

Fedora 21 server gnome install not starting

[Morgan Read]

Hello Folks

I know there's many questions about 'no graphical environment on 
server', but I've install gnome and enabled it.


After booting the display hangs following:
[ OK ] Started GNOME Display Manager
And, perhaps a few following such as starting virtualisation demon, 
waiting for plymouth to quit


Following a server install I ran the following successfully:
# yum groupinstall gnome --skip-broken
# systemctl set-default graphical.target

This this is what systemctl says:
]# systemctl status -l gdm.service
● gdm.service - GNOME Display Manager
   Loaded: loaded (/usr/lib/systemd/system/gdm.service; enabled)
   Active: failed (Result: start-limit) since Sun 2015-03-08 17:51:35

  Process: 1613 ExecStart=/usr/sbin/gdm (code=exited, status=1/FAILURE)

Any pointers would be very much appreciated.

Many thanks.

I don't know why no one else has mentioned this already.  In my opinion
it is much easier to install a minimal set, and then build your desktop
as needed rather than install the default, and get rid of Gnome.

I'm an XFCE user (with lightdm as login manager), and everytime I did a
fresh install, I used the minimal image.  You can even do a network
install.  During that I simply select the gui packages I need (some
subset of XFCE for me).  This way I have a very small set of gnome
packages.

  $ rpm -qa gnome\* | wc -l
  18

I know 18 is not a very accurate count, but it is more or less there.
Since you are using i3, I bet you can get the list to be even shorter!
Often people say disk space is cheap, why bother?  I have a tiny 20 gig
/ on my laptop, so it does matter to me.  On my desktop, I don't care.

Hope this helps,

It think you need to do:

There might be some other services that need to be enabled. This is

Hi Morgan,

I'm asking out of personal curiosity, so please don't take this as a
criticism.  If you wanted a GNOME desktop, why did you install Fedora
Server instead of Fedora Workstation?

Hi,
I have a fedora20 system acting as a backup server, and I've exceeded

I currently have a 3TB backup system using five 1TB disks in RAID5.
Restore times in case of disk failure are already exceedingly long, so
I'd like to consider another method of providing redundancy, and would
like suggestions.

I'd like to have 6TB of usable space using 2TB disks.

Is ext4 still best for this?

Some RAID variant or is there something better?

Are there any NAS projects that may be beneficial?

Thanks for any ideas.

A few years ago I read and article about the exact problem you are 
talking about.  Long rebuild times with larger HDDs.


Two things they pointed out is that with the amount of data on the 
drives, there is also an issue with the write errors being within the 
amount of data during the rebuild process.


Of course the cloud providers want you to use their services and you can 
see that with all the recent articles about the death of backups due to 
clouds.


I got rid of my raid arrays after I lost a drive and lost part of the 
data on a rebuild.  Still needed to use a different backup for recovery.


Some articles I have read are pointing out that people are looking for 
reliable file systems with error correction built in and then using 
normal backup techniques.


This is the same option that I am looking at for the future.

Hey Martin,

It appears that yum may have some "hidden" groups.

http://wiki.centos.org/TipsAndTricks/YumAndRPM#head-b3159dc0594ab59a5ae0c27d86c3815085064419

Perhaps this is what you need to get started.

Re: Fedora 21 server gnome install not starting

[Dan Irwin]

One really great reason to install Fedora server is that logging, using
rsyslog, works out of the box.

After learning this (this list, last week), I will be avoiding any desktop
type installers, preferring the server image for workstation and laptop
installs.

If you're concerned about rebuild times, go with more small drives and
move to raid6.

Another option is considering two 6TB drives in a raid1, per GB the
6TB Red drives are lower priced than the 2TB Reds. Of course, raid1
makes it more expensive in any case, but at reduced complexity.

And yet another option is GlusterFS either with multiple bricks on a
single node, or multiple nodes. These can even be done with ARM
boards. So you could have a volume that's for things you wan "3
copies" or, and have it automatically keep two local copies with one
async offsite copy; another volume that's more disposable, e.g. maybe
just one copy for VM images, and those would never get copied offsite.

CentOS 7's installer has Backup Client and Backup Server options as
Add-Ons, I haven't looked into what that is, but might be an idea
worth exploring.

Sure, it's fine, no complaints. I'd probably opt for XFS due to its
long standing optimizations for both hardware and software RAID,
parallel IO, etc. And piles of NAS, SANs, and even DVRs using XFS. It
has a huge install base for this use case.

lwn.net has recent reviews of Rockstor, EasyNAS, OpenMediaVault,
FreeNAS (BSD ZFS based).

Oh yeah, several things you need to check if you're using mdadm created RAID.

md/stripe_cache_size in sysfs defaults to 256, it needs to be higher,
probably 1024 but do some reading to get more specific advice. Low
values cause slow performance in general, but in particular rebuilds.

These too may be too low by default, in particular max.
/proc/sys/dev/raid/speed_limit_max
/proc/sys/dev/raid/speed_limit_min

A pernicious problem that's totally non-obvious and comes up on
linux-raid@ list all the time. Mismatching SCT ERC and SCSI command
timer. The former needs to be shorter than the latter. Both are per
drive, not per array.

smartctl -l scterc 
cat /sys/block/sdX/device/timeout

And don't forget period scrubs:
echo check > /sys/block/mdX/md/sync_action
cat /sys/block/mdX/mismatch_cnt

Btrfs isn't the default in Fedora 21 and isn't expected to be until
Fedora 23 or 24.

The Btrfs raid56 code has been in the kernel for a while, but only
since kernel-3.19 is btrfs replace, scrub, and self-heal possible. I'd
say it's now a good deal closer to stable than experimental, but
raid56 is still a gray area. I can't suggest enough having more than
one backup, but that's emphasized more if the primary one is on Btrfs.

pidgin video chat

[Amadeus W.M.]

Does anyone know how to do video chat in pidgin? I can't figure it out 
for the life of me. I click on a contact name and the chat window opens. 
Then, under Conversation -> Media I have 3 options: Audio call / Video 
call / Audio and video call. But all are inactive (grayed out) and so 
they can't be selected. Does this mean that pidgin has been compiled in 
Fedora without audio/video support? 

I am, however able to configure the Voice/Video Settings by going to 
Tools -> Plugins -> Voice/Video Settings, then click on the "Configure 
Plugin" button. So pidgin does see my camera and microphone. But what 
else do I need to be able to actually use them? 

I've searched the web for this, of course, and I couldn't find a 
definitive answer. All information is outdated, or for other 
distributions, or simply vague. For instance:

https://developer.pidgin.im/wiki/vv

or the user guide (which is really a FAQ):

https://developer.pidgin.im/wiki/Using%20Pidgin



Do I need to recompile pidgin with some non-free codecs enabled? 

Thanks for any help!

I too would love to know the answer to this! I've been just using 
another machine running Ubuntu (so that I can use Skpye occasionally!) 
But I'd rather use Pidgin on my "F"-Box!...LoL!
