Re: 32bit apps under amd64 and nvidia

Alex Moonshine — 2013-05-26T06:21:14

I think, as an alternative solution, you may download libxvmc1:i386 and
unpack .so files from it to /usr/lib (and continue to use debian driver
packages).

Hi Alan!

This will not work. The problem is missing libxvmc1:ii386, which got a 
dependency problem. There is a bugreport related to it. They say, it was fixed 
by adding a new libnvidiaxvmc1, but it is still not. Got the same problem 
still here. 

By installing libxvmc1:i386, it wants to deinstall several other applications.

Solution: Just install the installer from Nvidia's site. Works like a charm!

Good luck

First there is no such thing as "RAID0".  Second, "striping" is only fit
for temporary data.  The OP is concerned with permanent data storage.

Re: Debian 7 Wheezy Stable Released

I think so.  Yes.  I am not sure what to say there.  They are already
saying the right things.  Clean before the upgrade so that you can
tell what is old and what is new.  Merge and clean after the upgrade
to complete it.  But I think this should be communicated much more
strongly.  Because it seems that that many people do not know about
doing this and old forgotten files create problems in later upgrades.

32bit apps under amd64 and nvidia

Alan Ianson — 2013-05-25T23:57:13

I just installed wheezy on an amd64 machine and am trying to run a
32bit program but it doesn't run. I'm using the stock amd64 kernel and
the debian packaged nvidia drivers. I used to install an ia32 (or
somesuch) nvidia package to run 32 bit programs on amd64 with good
results but wheezy is multiarch and I'm not sure how to proceed.

TIA for any pointers.. :)

As Karl suggests it may be a problem with your DNS pointing. Try
looking at the return of :

and then:

Make sure that they return the same ip for the host.

Re: measuring RAID arrays performances

Yes, you are.  You're using only 2 disk drives.  The md/RAID10 module
with two drives will perform nearly identical to RAID1.

Adding insult to injury you are using 6GB partitions in your testing
setup.  The "layouts" of md/RAID10 are only of benefit when you use the
entire disk capacity, or a very large portion of it.  These layouts
obtain some advantage be changing the behavior of the disk head and thus
read latency.  With a 6GB partition on a 1/2TB disk drive, the heads
will never travel outside of a single track.

You really need to read and comprehend much more about md, or simply
listen to an expert:

For two disks, use RAID1.  PERIOD.  End of story.  Screwing with
anything else is a massive waste of your time.  If you have 3 or more
disks, then you can worry about layouts.

Re: cheap hw raid or raid software?

Stan Hoeppner — 2013-05-25T23:19:41

Correct.


This isn't a very good description.  There are non RAID HBAs that have
large heatsinks as well.  ASIC package (chip) size is irrelevant.  This
is a result of the lithography feature size (65nm/40nm/32nm) not the
complexity of the logic.


Real hardware RAID HBAs do have DRAM on board, anywhere from 128MB to
2GB.  Most RAID cards ship without the battery module.  It's optional.
And your price point is high.  Adaptec's entry RAID cards are very
reasonable.  Newegg has 5 models from $199-245.  All have 128MB DRAM and
support RAID1/10/1E but not 5/6.  So I'd say "$200+" is more accurate.
Most that support parity arrays are typically $300+.


If you're sticking with that Sil3114 card then yes, use Linux md/RAID
(mdadm).  Performance, compatibility, troubleshooting, etc will all be
better than fakeRAID.

sound synchronization in flash

Larry Johnson — 2013-05-25T23:15:27

Here's a somewhat silly problem I'd like to chase down (but wouldn't be a
disaster if it stays broken)

I've been navigating around my new wheezy install checking that everything
works (so far nearly everything does), but I stumbled on an odd little
issue.  I went to a flash pacman site (at
http://www.thepcmanwebsite.com/media/pacman_flash/ ) and the familiar
"chomping" sound effect is out of synchronization.  It's in sync on my
wife's Windows machine and was on  my former Fedora install.

Where should I start in diagnosing this?  ALSA?  I searched bug reports and
didn't find a good candidate for a similar bug.

measuring RAID arrays performances

Jean-Marc — 2013-05-25T22:36:43

Hi guys,

I am trying to measure the perf' of RAID arrays to be sure of the layout 
I'll use for my future set up.

Based on this article, RAID10,f2 seems to be the best set up:
https://raid.wiki.kernel.org/index.php/Performance

But if I create a RAID10,f2 array (ext4 FS) and if I compare its perf' 
against a RAID1 arrays using bonnie++, I do not see any big differences.

This is the command I used:
/usr/sbin/bonnie++ -s 5000 -n 128 -r 1024 -m Jessie -d /tmp/md99/

My RAID10,f2:
# mdadm --detail /dev/md99
/dev/md99:
         Version : 1.2
   Creation Time : Sat May 25 23:15:46 2013
      Raid Level : raid10
      Array Size : 5851136 (5.58 GiB 5.99 GB)
   Used Dev Size : 5851136 (5.58 GiB 5.99 GB)
    Raid Devices : 2
   Total Devices : 2
     Persistence : Superblock is persistent

     Update Time : Sun May 26 00:23:12 2013
           State : clean
  Active Devices : 2
Working Devices : 2
  Failed Devices : 0
   Spare Devices : 0

          Layout : far=2
      Chunk Size : 512K

            Name : debian:99  (local to host debian)
            UUID :
          Events : 106

     Number   Major   Minor   RaidDevice State
        0       8       37        0      active sync   /dev/sdc5
        2       8       53        1      active sync   /dev/sdd5


May be I am doing something wrong.

It's easier once you are comfortable with it. It does take some

And, I have just checked, using Synaptic, and, gpm is not installed.

libgpm2 ( "General Purpose Mouse - shared library"  ) is installed, 
however.

Funny - the cats here, do not share mouses, but, in Linux, mouses share

Ok, you installed Debian 7. How did you do it? You went for a desktop
or a bare install?

Now you have a problem. Nothing else whatsoever was installed after
booting into the new system?
