 That is a great thing that you are having 10+ years of experience, great.
And yes you perfectly seem hostile (with this email too). Your answers
might be precise and directions could also be good but way of handling
newbies is something poor, however, this point I am chucking (like an old
shoe). Though there are numerous people who have more than 15+ years of
experience and I have never seen them (or anyone of them) talking like this
but still have seen them landing people and newbies on moon. Moreover,
while your suggestions could be (I don't know much about Linux till now)
good but following them requires you too to be gentle in words, be
respectful to everyone [even to newbies, they too are persons, ;)- ], and
in return you would get respect. I always respect everyone and I know more
than 100+ people (having experiences 15+ years in information technology)
and I always pay them respect, but simultaneously I talk politely to any
newbie of any field, and it doesn’t harm me ever.

I doubt that.  All VMs are booting now with the latest CR kernel 
(2.6.32-131.17.1).  And it appears that bug is about xen not qemu.

I will clone the host and experiment some to narrow down the problem to a 
specific package.  Right now none of the CR repo libvirt or qemu packages are 
installed on the host.  So I really do not know for sure which is the bad guy.

Recent experience indicates... if the machine had any kind of warranty
with Dell, an authorized owner/technician should call Dell before doing
ANYTHING more with the drives.


With the dell system I was working with, I was walked through booting
into the raid controller software (bios level prior to OS boot) and
having THAT reassemble the array.

If they were mirrored, you should just be able to mount one and see what you 
can find. If they were striped, then you would need a controller

A development server that's in use is not a production server. Those are
visible to the world. I don't think it's unreasonable to go in, add a
drive group, add these drives to the group, and have it rediscover them
and present them to me. Why is that not a safe thing? Other than the
rediscover the RAID, it's no different than shoving an ordinary drive into
one of the hot swap bays and mounting it under /mnt.

let me see if I get this right... you don't want to play around with a server 
that's in production now but you are perfectly willing to play around with a 
server that's in production mode as long as it doesn't involve rebooting?

I think you have a strange notion of safe things to do with a live production

[CentOS] ext3 bug?

[Dennis Jacobfeuerborn]

Hi,
on one of my Systems I'm seeing a strange phenomenon. When I do a "ls 
/var/log/named/" that command just freezes. An strace shows that ls is 
endlessly doing this:

...
getdents(3, /* 66 entries */, 32768)= 3888
getdents(3, /* 85 entries */, 32768)= 5000
getdents(3, /* 70 entries */, 32768)= 4128
getdents(3, /* 80 entries */, 32768)= 4696
mremap(0x2b8b2b181000, 311296, 618496, MREMAP_MAYMOVE) = 0x2b8b2b181000
getdents(3, /* 82 entries */, 32768)= 4736
getdents(3, /* 50 entries */, 32768)= 2920
getdents(3, /* 53 entries */, 32768)= 3088
getdents(3, /* 82 entries */, 32768)= 4800
getdents(3, /* 73 entries */, 32768)= 4248
getdents(3, /* 54 entries */, 32768)= 3240

getdents(3, /* 48 entries */, 32768)= 2816
getdents(3, /* 59 entries */, 32768)= 3448
getdents(3, /* 66 entries */, 32768)= 3792
getdents(3, /* 60 entries */, 32768)= 3440

getdents(3, /* 49 entries */, 32768)= 2864
getdents(3, /* 67 entries */, 32768)= 3960
...

The problem is that this directory only really contains two relatively 
small log files. I cannot remove the directory because rm gets stuck with 
the same problem. The only way is to move the directory elsewhere and 
create a new one though apparently after a while the same thing happens.

So I decided to take the system offline and do a fsck. The check went 
through without a single error so apparently the filesystem is fine.

Does anyone have an idea what could be going on here?

Regards,
   Dennis

Sorry, let me give my conditions a bit more: I don't think I can reboot
the server - I believe it's currently in use as a development machine by
one of the teams, so I can't play around with it.

I believe it's the same kind of controller, so that's ok. I'm using MSM
for the above reasons, and that the cli isn't installed.

Playing with this thing, I believe I want to create another drive group,
not just add another RAID to an existing one, which just seems as though
it could get really ugly. But when I click on the controller, I can then
get to "Go To" -> controller, which will let me create a new virtual
drive, but drive group is all greyed out still. Further, I don't see
anything that would let me investigate what the documentation seems to
call a "foreign RAID".

Hope that gives y'all a better picture of my environment.

I wouldn't waste the time with MSM - I would simply use the BIOS configuration 
for the RAID storage which can easily look at the drives for RAID configuration 
and load it if it can find it.

That said, I would suspect that the RAID controllers would have to be identical

Right, and Dell's PERC is an OEM-rebranded LSI controller. MSM understands
them fine.

Of course, I don't seem to have the command line tool, and when I click on
Go To, and try controller, everything is greyed out.

Correct me if I'm wrong, but isn't MSM for LSI/3ware cards?

If the drives didn't come off a PERC, you probably can't recreate the array
on a PERC - I'm sure you know this, but it's worth verification.

Re: [CentOS] how to install standard software on systems with heterogeneous hardware?

[Scot P. Floess]

Ah OK - sorry if I misunderstood you...

I definitely see your point.  I suppose for me if I have to do something 
more than once, I like automation (like Cobbler).  I do a ton of 
tinkering, trashing machines, spinning up VMs, etc - it just became 
tedious.  Truth be known - initially I spent sooo much time learning 
Cobbler.  But that time has since paid off...


Quite honestly, the way Cobbler is structured - the templating is so very 
easy to learn...I think I spent one morning reading up on it and I was 
proficient enough to denote packages for any given machine (really why I 
responded in the first place)...

No, I was just wondering about the tradeoff in time spent learning yet
another system-specific template language vs just executing the
commands directly (in windows, in parallel so you don't have to
wait...).For 100+ similar machines I'd expect it to be worth it.
Not that automation isn't good, but if you have the list of packages
you want to install in the first place, it's not all that hard to do
it yourself.

If you are interested in Cobbler - I'd be more than happy to give you some
pointers, as well as the kickstart file I use - it should be reusable for
you...especially with CentOS 6.0 and earlier plus Fedora 15 and earlier
(some changes to kickstarts with Fedora 16 - notably  %package needs a 
%end)...

Anyway, I do a ton of virtualization work at home (its a hobby), and I use 
Cobbler for them as well as my four baremetal machines...once you learn it 
- its a huge time savings...and very reusable...

[Note: Johnny's advice is good, and this reply is more addressed to the OP than 
to Johnny, as he already knows what I'm getting ready to post.  The OP may not.]

This will give all the same versions of the packages, which will mostly work, 
unless a version disappears between the 'rpm -qa' and the 'yum install' 
invocations.  I've had that happen before, so in those instances, I use the 
helpful

rpm -qa --queryformat "%{NAME}.%{ARCH}\n" > somefile

line so that I get the names and the arches, but no versions (arch only needed 
if multilib desired, of course).  Newlines are cosmetic, of course, and aren't 
really required by yum install.  To get a listing of all the --queryformat 
variables, use:

rpm --querytags

and see the rpm man page for more information about --queryformat.

I also tend to sort my package names in the pipeline so that somefile is 
human-readable and that helps when duplicating the major packages between 
versions (I've used that sequence going from one Fedora version to another, for 
instance).

And a backup of /etc/yum.repos.d along with the gpg keys helps get things in 
order.

I don't know - just trying to help.  I have 4 machines at home...and I use

I spent to learn it.  When I lost a harddrive in my laptop, I replaced 
it...selected the Cobbler system record for it...and my laptop was ready

Cobbler uses a nice templating engine (Cheetah) and I've managed to use
that within the kickstart file Cobbler serves up to specify packages to
install for a given machine.  So for example on Machine A, I can have the
foo package installed and on Machine B install the bar package...

Cobbler even supports PXE booting clients to get installs started...


How long does it take to learn the templating language compared to
sshing to a few machines in separate windows and pasting in a 'yum

First question: *how* heterogeneous? Do you have 32-bit systems, and
64-bit systems, and Itaintiums?  AMD and Intel? Or are you just talking
about peripherals?

How about building one fully, getting a list of installed packages that
does *not* mention the architecture, then, on each machine, yum -y install
`cat packagelist`? Yes, I am assuming they're bootable, and have yum, but
nothing else - a minimal install.

How long does it take to learn the templating language compared to
sshing to a few machines in separate windows and pasting in a 'yum
install list_of_packages' command?

I can wait.  I am still experimenting with KVM before
going live and I need to see what trouble putting our

Re: [CentOS] how to install standard software on systems with heterogeneous hardware?

[Scot P. Floess]

You could setup Cobbler and koan install the other machines from the 
Cobbler server.

Cobbler uses a nice templating engine (Cheetah) and I've managed to use 
that within the kickstart file Cobbler serves up to specify packages to 
install for a given machine.  So for example on Machine A, I can have the 
foo package installed and on Machine B install the bar package...

Cobbler even supports PXE booting clients to get installs started...

If I was doing a thousand machines, i would build an RPM to do it ...
otherwise with just 4, I would just use this on the original:

rpm -qa > somefile

rsync somefile to the other machines and then:

yum install $(cat somefile)

I would then rsync the config files from the other machine to the new one.

many SOHO firewall/routers incorporate DNSmasq, which is a combination 
DHCP/DNS service that both acts as a caching forwarder for external 
lookups, and provides the local clients with DNS names based on their 
current DHCP registrations.   This works quite nicely for the use case 
of the OP.

[CentOS] how to install standard software on systems with heterogeneous hardware?

[Thomas Burns]

I've been thinking about ways to proceed if I need to set up 5
machines with basically identical software but somewhat variable
hardware. A simple approach would be to just set up my golden system
and clone the disk, but the hardware differences would probably cause
problems.

One approach that appeals to me is to install minimal centos on the
first system, add a few rpms after installation, do my desired config
file tweaks, then somehow generate an rpm that depends on all the
post-install rpms and contains my custom versions of the config files
I tweaked. Then, to set up the other 4 systems, I'd use the kickstart
file from the first, then yum localinstall my custom rpm, which would
install all the dependencies and tweak all the config files. I assume
the centos install would deal with the hardware differences. Does this
idea make sense? What happens when two different rpms want to provide
the same config file?

Are there any other simple alternatives I have overlooked? What is the
best practice when setting up identical software on multiple systems
with heterogeneous hardware?

mahalo,
Dave

just to clarify some things...

NETBIOS is a rather chatty (ie, noisy/traffic generating) for a local subnet. 
Yes, this can be a convenient way of being able to refer to a computer by its 
name and the price you pay for that convenience is a fair amount of broadcast 
traffic by all computers that support this protocol (Windows, Macintosh or 
Linux using NMBD).

NETBIOS does not in any way provide DNS services. It is relegated to the local 
subnet only and almost always what is designated as non-routed IP space 
(10.x.x.x, 172.16.x.x, 192.168.x.x)

UNIX/Linux has a reasonably simple method for maintaining DNS names in 
/etc/hosts where you can simply set them, ie
192.168.1.1 srv1 srv1.mydomain
192.168.1.2 srv2 srv2.mydomain
etc.
You can also do this on Windows systems - edit 
C:\Windows\System32\drivers\etc\hosts

If you want Dynamic DNS on your LAN, you are going to find that the typical 
home/SOHO routers are insufficient with short lease times, no memory storage 
for previously registered DHCP addresses and no ability to actually provide 
real DNS (other than forwarding to some other DNS server) and thus, no DDNS. 
Thus if you really want to have dynamic DNS on your local LAN, you would want 
to install bind and dhcp packages and configure them (not the easiest thing to 
do but not entirely difficult either).

Your router is probably giving out its own IP as the nameserver and
caching locally anyway.

Can't you add local entries to the router...?

Setup a local DNS (if your router cannot do it).
Or simply add them to each /etc/hosts
For 7 computers, I would just use /etc/hosts...

Do not be sad!
At least with CentOS 5, you can install the 'caching-nameserver' package.

Can this router have DNS entries added for local hosts?  Some SOHO type routers 
can do this, but I'm not that familiar with your particular router.

Indeed.

There is no one correct way.  But here are a few possibilities for you:
1.) DNS entries in the D-Link router;
2.) static hostnames in /etc/hosts (you'll need to set the router up to always 
hand out the same IP address for each machine; most SOHO routers can do this, 
but it may not be obvious how to make it work)
3.) Run a separate DHCP and DNS server on the LAN and not use the router (for a 
larger installation this would be the preferred way to do things, but for a 
small number it's not ideal).

Dynamic DNS; your router may be able to do this for you.

Yes.  More than one option exists for this; for CentOS 5 at least you can just 
'yum install caching-nameserver' and 'chkconfig named on' (and then 'service 
named start') and it should come up; I haven't used that setup in some time, 
though, so not sure how nice that plays with DHCP.  There are other options, 
but that is the main one that is in the CentOS distribution's main repo.

Hope that helps.

There's a separate dictionary of translated text strings (called a
catalog) for each language.  Those translations are looked up and
substituted for the default text based on the locale or language
settings in the environment.  If the number is stored in the catalog
as part of the string, you could see this effect.

It appears that either the catalogs have not been updated along with
the packages that make reference to them (which would be a bug), or
the updated catalogs have not been installed because they are part of
a "language pack" that is not listed as a dependency of all the
packages that refer to it (which likely is a deliberate optimization).

Right now, there are 50-80 mails per day on this mail list alone, 
without interactive one-sentence mails in 2-3 people conversation.

And there are 1000+ receivers of mail from mailing list (1+ million of 
installations ), not interested in your problems. For them, reading 
interactive mail is FUD, unnecessary junk wasting their time. Imagine 
communication for just 10 beginners asking/posting 20-30 mails (with 
replies of others).

So please respect them and use IRC/Forums for "trivial" support, and use 
this mailing list for more heavier questions and discussions (not 
producing high mail volume).

[CentOS] How to make nodes in my local LAN see each other's names

[Timothy Madden]

Hello

Sorry for the (I guess) simple question, but:

I have 7 computers under one 8-port router (D-Link DIR-100, firmware 
v1.13EU) in my network (actually in a sub-network) and they do not see 
each other's host names.

The router has the 'DNS relay' option enabled, and all 7 computers use 
the router as the DNS server, which in turn will forward DNS requests to 
the ISP DNS server. That way I can understand that simple, plain, 
default DNS is not enough for my boxes to see each-other's names.

Windows has a nice (or not) way to resolve the problem: CIFS (Samba) 
server names are automatically included in the name resolving procedure. 
I know I can do the same with my CentOS boxes if I install samba on each 
of them and add 'wins' to the 'hosts: ' line in /etc/nsswitch.conf, but 
somehow I think installing cifs on every node just to get my local 
machine names to resolve properly to the IP addresses is not the right 
way to solve my problem ...

What is the way to have all computers in my simple network know each 
other by name ?

Is it possible to have the name resolving procedure used by the system 
automatically recognize a new machine added to my network, when I try to 
access it with right host name, like WINS can ?

Also, I hear Linux does not have, by default, a cache of resolved names 
(like Windows does), and I find that to be a sad thing. Why should the 
default be set so that I contact the ISP DNS server for each and every 
web page I hit ?

Is there an easy way to install a caching name server on my each 
machine, and make sure my system is using /that server/ to resolve names ?

Thank you,
Timothy Madden

Re: [CentOS] DHCP_HOSTNAME in ifcfg-eth0

[Scot P. Floess]

Sounds to me like you want to set up DDNS internally?  I do that for my 
home network - but you need to have both DHCP and DNS working 
together...meaning DHCP needs to be able to update the DNS server with the 
names of the DHCP clients.  I've got a Linksys router and have never 
gotten that to work with it (I haven't tried), but I have a CentOS box 
acting as both my DNS server and DHCP server.  I also spin up VMs that use 
DHCP...my kickstart file actually write the DHCP client name into 
ifcfg-eth0, so when the DHCP clients start up I can refer to them by 
name...

Can't you just do
  DHCP_HOSTNAME=`hostname`
?

Many of the config files are just parsed as shell scripts, so this

I think I know some of what is causing what is going on now...
After a little testing with a format string of 
 
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{INSTALLTIME:date}"\n'
I found I got different results based on the LANG environment setting,
which led me to try it with the SUMMARY field too.

###start with a normally configured terminal
$ cd /to/your/CentOS/mirror/
$ locale |grep LANG
LANG=en_US.UTF-8
$ rpm -q \
  --qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n'  \
  -p 5.7/os/i386/CentOS/bash-3.2-32.el5.i386.rpm
"CentOS","bash","3.2","3.2-32.el5","i386","The GNU Bourne Again shell
(bash) version 3.1."

#now change LANG to what I see from cron
$ export LANG=
$ locale |grep LANG
LANG=
$ rpm -q \
  --qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n'  \
  -p 5.7/os/i386/CentOS/bash-3.2-32.el5.i386.rpm
"CentOS","bash","3.2","3.2-32.el5","i386","The GNU Bourne Again shell
(bash) version 3.2"

Why does a number in a text string change based on LANG?

and for added fun... look at an agg package from epel
$ export LANG=en_US.UTF-8
$ rpm -q --qf
'"%{VENDOR}","%{NAME}","%{VERSION}","%{VERSION}-%{RELEASE}","%{ARCH}","%
{SUMMARY}"\n' agg
"Fedora Project","agg","2.5","2.5-9.el5","i386","Anti-Grain Geometry"
$ export LANG=

{SUMMARY}"\n' agg
"Fedora Project","agg","2.5","2.5-9.el5","i386","Anti-Grain Geometry
graphical rendering engine"

Why does the string length change this dramatically based on LANG?


Well I guess I at least know what I need to do to the script to have it
be consistent.

I might even get around to filing a RH bug, because this does not seem
to me to be a correct behavior to me. does anyone here see these changes
as correct behavior (and why)?

Sorry for the wrong wording: what I want is the DHCP client to send the 
hostname when a lease is requested, but I do not want to give dhclient 
any explicit hostname to be sent.

I want dhclient to read the hostname from `hostname` or from 
/etc/sysconfig/network or any other way, and use that name to send the 
hostname to DHCP server.

No, your priorities are *not* set correctly.  CR must be at the same or
lower-numbered priority than the base and updates repos.  If base is at
priority 1, then CR should also be at priority 1.

I think the confusion comes in because a lower number means a higher
priority.  In order for the CR repo to update the base packages, it must
have the same or a higher priority (meaning the same or a lower number).

For some reason I think you need to have "HOSTNAME=" in your 
/etc/sysconfig/network file .. meaning make the variable blank.  There is 
also a dhclient option you can create in /etc/dhcp/dhclient-.conf 
something like send fqdn.fqdn  but usually you don't need that 
if your use DHCP_HOSTNAME correctly ...

Hi Timothy,
I've in my config file:

DHCP_CLIENT_ID=st00ni0029
DHCP_HOSTNAME=st00ni0029
 
That works for me.

[CentOS] DHCP_HOSTNAME in ifcfg-eth0

[Timothy Madden]

Hello

Is there a way for the dhcp client to send the current host name of the 
machine when requesting a lease ?

Currently I have to include a line like
DHCP_HOSTNAME=appserver2
in my /etc/sysconfig/network-scripts/ifcfg-eth0, but I would like to 
tell the dhcp client to just 'also send the hostname' and then the 
client to get the current hostname itself, instead of having the name 
hard-coded in the ifcfg-eth0 file.

I am trying to get my router to know the names of all my CentOS 
machines, as currently I can access none of my CentOS machines by their 
node name (I get 'unknown host' upon name lookup) and maybe it will help 
if the router knows all the computer names.

Thank you,
Timothy Madden

i am taking into account your lack of knowledge. IF LiveDVD lacks some 
of the packages installed by default from installation DVD, then you 
will not know which those packages are. That was the whole point of my 
suggestion to go with regular installation DVD. I haven't got around to 
testing LiveDVD so I do not have the answer.

If you have time to risk it (play/learn) then by all means install from 
LiveDVD. It is not wrong, just might be the longer/harder way of 
reaching the same goal. And it may not be harder at all. Your 
choice/preference.

http://www.centos.org has links to Wiki and Forums, and this mailing 
list is available also, so you can investigate/learn/ask.

My advice is to download LiveDVD for testing porposes, but regular DVD 
for installation. That way you will not miss out on anything from 
regular installation (in case LiveDVD is missing anything).

CentOS after installation is exactly what RHEL/upstream distributes, so 
there can/will be missing nVidia/ATI and possibly some other drivers. 
Those can be found in third party repositories 
(http://wiki.centos.org/AdditionalResources/Repositories) so do not 
worry about it, you will be able to set up your PC with all the drivers, 
with little meddling.

CentOS hasn't published a Deployment Guide for version 6. The 
package management software hasn't changed significantly from 
version 5. You can see the docs for RHEL6 but you need to figure 
out which parts don't apply to CentOS.

Thanks for the link. Following the trail I could see several bugs 
reported in bugzilla.gnome.org. The problem I have is related to the 
version of Gnome:

CentOS 5.7: Gnome 2.16 >> Does not work as I expect.
Debian 6: Gnome 2.30.2 >> Works as I expect.
Center 6: Gnome 2.28.2 >> Works as I expect.

Thank you all for your responses.

If you install from LiveDVD, you will get exactly the same things 
that are available on the Live system before installation. You 
can use the normal CentOS software management tools after 
installation to add packages form software repositories on the 
Internet.

Yes, I had alredy tested and it works, logging out of Gnome disconnect 
from NAS but also kill processes running when I just wanted to release a 
volume SMB.

I know it's not a good solution from the point of view of security, but 
they work like that for a long time and I just recently work here. 
Furthermore I'm not familiar with this machine and the services that 
provide. Also looks set to be replaced within a couple of months, so I 
did not want to spend much time, changing the way users work, and 
risking of breaking something in a compute server used constantly with 
something that has a period of life so short.

oh thanks for this explanation. Yes I wanted to know this one only. and
bin-DVD torrent, I guess contains both the DVDs (which separately are
written as DVD1 and DVD2). Okk..but I have to download the LIVE one since I
have to check also(if it gets adapted or not...) Said that, but I don't
know if LIVE DVD is one only or two (but on the website its one, at
http://mirrors.hns.net.in/centos/6.0/isos/x86_64/ and may be after
installation of one DVD it might be downloading things from the net..which
are left aside for which bib-DVD has two parts)

That was it - I guess I didn't read the man page well enough. I was providing

Rajagopal was Totally INCORECT. He did not pay enough attention and made 
a mistake.

You asked about difference between DVD and LiveDVD torrents, not between 
DVD1 and DVD2.

Correct answer:
- LiveDVD is meant for testing purposes, and it *should* have 
possibility to install system on the hard disk. It can be also used to 
access dead system for repairs or data salvage.

- Regular DVD is for default installation media, consisting of 2 DVD's. 
In default configuration only DVD1 is needed.

CentOS-6.0-x86_64-LiveCD.torrent(which

I found at

Which one I have to download and install? Further at the same page (i.e.,

options of DVD1 and DVD2, so are these two more I have to download?
  

The complete install with multiple language support is on 2 DVDs

Also for what purpose we have 'minimal' and 'netinstall'?
  
Minimal is just the very minimum of packages to have a very basic 
machine running Linux
Netinstall is where the install system gets the installation files 
directly off the internet to complete the installation

Its now included in the 6.1/os builds; I'll get it pushed into the CR/

I have deployed Zabbix successfully to remotely monitor about 240+
