Re: a few questions about SL admin best practises

[Faye Gibbins]

Hi,

 We also found that using LVM gave a ~10% performance hist but we still 
use it as it is so flexable it solves otehr problems that override the loss.

No reason to use LVM. The traditional "md" software raid is much simpler
and easier to manage (only one tool to learn - mdadm, compared
to the 100 lvm management programs). Historically, LVM is a knock-off
of XLV which was the companion partitionning tool to SGI's XFS filesystem.



  thoughts?  i'll always allocate /boot as a regular partition but
unless there are compelling reasons not to, i always recommend LVM as
the standard.



Your /boot partition has to be mirrored across both of your system disks.
If it's only on one disk and it fails, you have an unbootable machine,
regardless of what tool you used (lvm or md).

With "md" it is very simple, /dev/md0 is the system partition mirrored
across /dev/sda1 and /dev/sdb1, there is no need for separate /boot
partition, GRUB happily installs on both /dev/sda and /dev/sdb, and
your machine happily boots if either disk explodes.

To do the same with LVM, you probably have to read a book and take
an advanced sysadmin class; and forget about getting it to actually
work without the help of this mailing list.

SL6.0 is based upon Red Hat Enterprise Linux 6

(section 12.6.1) says
A PAE enabled processor is a minimum requirement
for the x86 variant of Red Hat Enterprise Linux 6.

Basically SL6 does not support your computer.

Re: Ekiga on SL6?

I had the same experience on a fresh SL6 (x86_64) install.  The sound
support on other applications is a bit erratic but mostly works.  The
camera Ekiga doesn't see and the audio too work in skype (the latest
Fedora version) and EVO and the camera in cheeze.  Alas, I did not spend
much time on it since this was not a major issue for me.  If someone has
solved this problem or knows whether TUV has a bug report it might be
useful to know.

I should have kept googling last night I eventually found this:

https://bugzilla.redhat.com/show_bug.cgi?id=666256

in which TUV seems to be saying "we'll look at it some time later".

Maybe I'll try building the latest ekiga from sources...

I am sure I can speak for the community and offer a warm welcome to you both.

2.6.38-UL1 ITB release of 2.6.38 UL1

[Nathan Yehle]

Fellow Cluster Mechanics and interested parties,

I managed to get 2.6.38 to build as a kernel rpm which works with our SL5.5 
cluster here and has tunings for our storage configuration.  We are seeing up 
to 2x the speed with the newer kernels enabling CONFIG_PREEMPT_NONE.


Check it out here:
http://twiki.mwt2.org/bin/view/ITB/UltraLightKernel

Comments welcome.
