XENserver - post-install-skript (beispiel für e1000e)

2009-01-26T22:28:00.001+01:00

Zum Einbinden der neuen Intel Gigabit Desktop Adapter CT PCIe habe ich folgendes post-install-skript verwendet.

#!/bin/sh

(
echo "running post installation"

# wir befinden uns in / (installation-root)
# zielsystem ist gemountet in /tmp/root

# installation neuer Treiber w/ Unterstuetzung Intel 82574L (Intel Gigabit Desktop Adapter CT)
wget http://192.168.178.11/xen500/driver/e1000e.ko
cp e1000e.ko /tmp/root/lib/modules/2.6.18-92.1.10.el5.xs5.0.0.394.644xen/kernel/drivers/net/e1000e/

# update-pciids
wget http://192.168.178.11/xen500/driver/pci.ids.tbz2
tar xjf pci.ids.tbz2 -C /tmp/root/

# NIC vor- und -nach dem Entladen/Laden
ifconfig -a > /tmp/root/ifconfig-a
modprobe -r e1000e
insmod e1000e.ko
ifconfig -a > /tmp/root/ifconfig-b

# fuer das install-log
ifconfig -a

echo .....

XENserver 5.0.0 answerfile (automatic installation)

2009-01-26T21:35:00.002+01:00

Wenn man den XENserver mittels Auto-Install (ohne PXE) installieren möchte, so kann man die entsprechenden Parameter auch im CD-Boot-Prompt angeben.

boot> /boot/isolinux/mboot.c32 /boot/xen.gz console=tty \
--- /boot/vmlinuz root=/dev/ram0 console=tty0 ramdisk_size=32768 \
answerfile=http://installserver/answer/host/answerfile.xml install \
--- /install.img

Und schon geht es los mit der vollautomatischen XEN Installation.

XENserver 5.0.0 - installation via http-repository

2009-01-26T17:58:00.003+01:00

Um XENserver 5.0.0 via http-repository zu installieren (und hier ggf. noch eigene Treiber etc. einbinden zu können) habe ich folgende Schritte vorgenommen:

mkdir -p /data/xenserver/5.0.0/{install,driver}

Kopieren der CD1 (xenserver)

cp -a /media/cdrom0/* /data/xenserver/5.0.0/install/

Kopieren der CD2 (linux support)

cp -a /media/cdrom1/* /data/xenserver/5.0.0/install/

Anpassen des Webservers (httpd.conf)

Alias /xen500 /data/xenserver/5.0.0

Driver-Repository

Eigene Treibermodule können unter /data/xenserver/5.0.0/driver abgelegt werden.

Probleme: Ggf. ist ein Treibermodul bereits geladen und es kann daher ein Modul mit gleichem Namen nicht (über)laden werden. Hier ist (noch) manuell einzugreifen mittels modprobe -r modulname . Ebenso könnte es sein, dass die pci.ids nicht aktuell sind. Dann sind die korrekten im Installationsroot als /usr/share/misc/pci.ids abzulegen.

Booten mit der 1. CD

Load a driver
Mediatype: HTTP/FTP
Repository: http://myserver/xen500/driver

Ggf. muss hier auf Konsole 2 (mittels ALT+F2) o.a. Handarbeit vorgenommen werden.

Alternative: PXEboot

RHEL52 - java profile

2009-01-25T22:46:00.002+01:00

Um in RHEL5 auch immer das passende JAVA mit entsprechenden Umgebungsvariablen gesetzt zu haben und hat man auch stets die "alternatives" angepaßt, so ist die Umgebung in der /etc/profile.d/java bequem zu setzen.

/etc/profile.d/java.sh

#!/bin/sh

JAVA_BIN=`dirname $(/usr/sbin/alternatives --display java | /bin/awk '/Current.*best.*version/ {print $NF}')`
JAVA_HOME=`dirname $JAVA_BIN`
J2RE_HOME=$JAVA_HOME/jre
JRE_HOME=$JAVA_HOME/jre
export PATH=$JAVA_BIN:$JRE_HOME/bin:$J2RE_HOME/bin:$PATH
export JAVA_BIN JAVA_HOME J2RE_HOME JRE_HOME

XENserver - Automatisches Provisionieren von RHEL5.2

2009-01-25T22:09:00.003+01:00

Unter der Annahme, dass wir auf xen211 installieren wollen, können wir folgendermaßen eine Kickstart Installation vornehmen.

#!/bin/sh

TIRI_UUID=$(xe vm-install new-name-label='r5.2-x86_64' template='Red Hat Enterprise Linux 5.2 x64' sr-uuid=$(xe sr-list params=uuid host='xen211' name-label='Local storage'|awk '{print $NF}') on='xen211')
xe vif-create device=0 network-uuid=$(xe network-list params=uuid bridge=xenbr0 | awk '{print $NF}') vm-uuid=$TIRI_UUID

xe vm-param-set uuid=$TIRI_UUID other-config:install-repository=http://192.168.178.10/yum/5Server/os/x86_64
xe vm-param-set uuid=$TIRI_UUID PV-args='graphical utf8 ks=http://192.168.178.10/yum/kickstart/ks-r5.cfg ksdevice=eth0'

xe vm-start uuid=$TIRI_UUID

XENserver - lokale DatenLV erstellen

2009-01-25T21:58:00.003+01:00

Um lokale Backups oder andere Sachen bequem ablegen zu können, empfiehlt es sich, eine eigenes Volume zu erzeugen.

Zunächst läßt man sich mittels vgs die verfügbaren Volumegroups anzeigen.

# vgs
VG #PV #LV #SN Attr VSize VFree
VG_XenStorage-05311684-f218-401a-0caa-dfcce1a83d68 1 8 0 wz--n- 457.99G 229.39G

Jetzt kann man in die bestehende VG ein logisches Volume "datalv" erstellen.

# lvcreate -v -L 200G -n datalv VG_XenStorage-05311684-f218-401a-0caa-dfcce1a83d68

Logical volume "datalv" created

Die LVs sind noch zu aktivieren, so dass der Host auch Zugriff darauf hat:

# vgchange -ay
8 logical volume(s) in volume group "VG_XenStorage-05311684-f218-401a-0caa-dfcce1a83d68" now active

Nun noch ein Dateisystem drauf und mounten und das LV steht bereit.

XEN - Neues Physikalisches Interface ethX wird als __tmp{randomid} angezeigt

2009-01-25T14:29:00.000+01:00

Bei der Installation eines neuen Netzwerkadapters wurde dieser zunächst gar nicht erkannt.

lspci zeigt das Gerät als "Unknown Device" an.

08:00.0 Ethernet controller: Intel Corporation Unknown device 10d3

Also habe ich mit Hilfe des kernel-xen-devel Pakets den Treiber für den Intel Corporation Gigabit CT Desktop Adapter von der intel Website recompiliert.

modinfo zeigt die Modulparameter

Das Interface taucht allerdings noch gar nicht auf, da wir es XENserver noch nicht bekannt gemacht haben.

xe pif-scan host-uuid=9f3466c1-1d70-4d98-bdd3-afd5a2996e13

Aber leider taucht das Interface nicht als ethX, sondern als __tmp{randomid} auf

ifconfig -a

Abhilfe schafft folgendes Vorgehen:
