pvresize on a cLVM
Hi,
I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done it).
On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it.
Has anybody done this on a cLVM PV ?
I'm trying to rescan the devices, but I can't "see" the new size. And,
googling on it I can only find RHEL5.2 responses.
Thanks in advance,

One for the Cisco experts...
I have a Cisco 6509 switch that I'm monitoring with SNMP from a
CentOS5 machine. SNMP polls are the only access I have to this
device, we are not allowed to log on via telnet.
How can I find out which port on the switch a particular server is
connected to? I was hoping that this is somehow possible using the
mac address and the data gathered from snmpwalk/snmpget requests but
I'm not

SNAT Logging
Hi All,
I'm running our network with an 10/8 IPv4 subnets, with an SNAT catch all
rule on the iptables firewall to the world.
Is there a pratical way to log each connection? Maybe an "automatic hotspot"
wich will assign an "external" IP to each "internal" one, and log it.
What are you using folks?
Thanks,
Antonio.

32bit HVM within CentOS5 x86_64+xen3?
Hi *!
I have to install a xen virtualization host that will start with 4GB RAM
and will maybe grow to 8GB in the future. And there has to be a 32bit
winXP domU. Is CentOS5(.1) x86_64 able to run 32bit HVMs or do i have to
stick with i386/PAE?

-----BEGIN PGP SIGNED MESSAGE-----

I have a problem with a couple of my centos servers hitting a kernel

I find them sitting at a panic screen like this:

Two questions:
1) How do I make it reboot after a panic instead of sitting in a hung state?

CentOS 5.0 and php-yaz
Hi,
I have a CentOS 5.0 LAMP server, and I need to install the php-yaz
module to implement the Z39.50 protocol (which handles data exchange for
public libraries).
I've already done this with Debian (a one-liner: apt-get install
php-yaz) and also on Slackware (more complicated: compile Yaz, rebuild
PHP).
Has anyone here ever done this on CentOS? What would be the most
orthodox method to

Red Hat Directory Server
Anyone played with or know the status of Red Hat Directory Server on
CentOS 5? I had some problems getting this to work on CentOS 4.4, but
am very interested in using this instead of regular OpenLDAP as it
supports two way synchronization to Active Directory.

Switch to measure traffic at IP level?
Hello all:
Is there a network switch that will give me traffic
stats at an IP address level?
Right now, I only get statstics at a port level, but
that does not help since each of my servers run several
virtual machines and I need to measure traffic
per virtual machine.
Thanks,
Neil

5.6 is out, great my first upgrade didn't work...
5.6 is out. That is good news.
I did a yum update on one of my non-critical server, and the server
stoped responding to ping after the reboot, and never answered back.
It's now been 10 minutes, so I'll have to take a ride to the colo...
Nice work dev team, keep up the good work. Let's hope that C6 will come
soon ! I'm eager to upgrade.

Monitoring bandwidth, latency, packet drop.
Hi all.
I am currently thinking about monitoring a network link (bandwidth,
latency, packet drop). I have a centos server which is connected to
providers network through a switch. How to test the link? Should I:
- use ICMP to ping gateway and collect staistics of time/packet loss/etc.
- use software like here:

Balance of tcp traffic
Hello,
Anyone know a method to discriminate traffic by preference?, for example
this channels:
High preference traffic.
Low preference traffic.
All traffic in the same interface eth0, and two servers in the same
machine, one in slow channel and one in high preference channel.
When high preference channel is not used low preference channel should
be caught all line speed.
Anyone know if tc

backup / compressed copy
Hi,
I think about buying a NAS-server from Sun. To backup this server I want
to use our central to-tape backup. For whatever reason ppl are asking me
to make one compressed copy to disk and only backup this copy.
So to reduce load I'd like to have a script that:
identifies changed files only (using md5?)
copies them
and compresses them
storeBackup.pl does something similar, but keeps

EMC CX4 Clariion
Hi,
We had received a new EMC storage (Clariion CX4) and the EMC analist has
told us that CentOS aren't on their support list, but RHEL are :)
Well anybody on the list has a CentOS host talking (iSCSI) with an EMC storage,
preferably using the EMC Powerpath software, and can talk about you experience?
Or I will need to buy some REHL licenses ?
I'll put my hands on it only next

[OT] External RAID storage / NAS
Hello List,
I need storage for my home network - lots of storage. It's going to
hold pictures, home movies, music, other bits of data, etc.
I'm looking to start at about 500 GB, but I'd need to eventually grow
that to 1 TB, or more. I also want something that is quiet, has hot
swappable drives (not necessary, but a plus), is fairly easy to manage,

local centos repository upgrade from 5.3 to 5.4
Hi list,
I run quite a few centos 5.3 servers and have a local yum repository
which is working fine.
Below a list of what I'm rsyncing at the moment + an extract from my /
etc/yum.repos.d/CentOS-Base.repo file
I copied the OS directory from the install media and ran createrepo on
that dir.
I would like to upgrade my servers to 5.4.
I was wondering if I could simply replace the
