Bonjour à tous,
Pour un projet que je compte présenter aux
cours, j’expérimente DRBD et heartbeat pour approcher les bases de la
haute disponibilité.
Je suis un débutant sous Linux et encore plus sous Debian ( j'ai commencé avec
Ubuntu).
J’ai suivis plusieurs tutoriaux pour mettre en place DRBD et heartbeat.
DRBD ne pose pas de problèmes.
Par contre heartbeat, arg, ca parrait simple mais rien ne marche.
De plus je fais la configuration en style V1, donc c’est facilement lisible.
Lorceque je lance heartbeat via:
Hello everyone,
I try to experiment DRBD and
heartbeat.
I am a beginner in Linux.
I followed several tutorials to develop DRBD and heartbeat.
DRBD works perfectly.
Also I am setting V1 style, so it is easily readable.
When I start heartbeat via:
/etc/init.d/heartbeat restart
I get to folow message:
Stopping High-Availability services:
Done.
Waiting to allow resource takeover to complete:
Done.
Starting High-Availability services:
2010/05/31_22:12:33 INFO: Resource is stopped
Done.
And the ip alias is not created
My stucture look like this
LAN0 sur eth0: 192.168.0.0 /24 # Lan users + heartbeat
LAN1 sur eth1: 192.168.1.0 /30 # Lan DRBD: is working.
LAN2 sur eth2: 192.168.2.0 /28 # Lan apps servers: Not yet used.
Heartbeat have 2 node: frontal1 and frontal2
Frontal1| eth1------DRBD------eth1 | frontal2
------------ ------------
eth0 _____________________eth0
| |
|______________________ |
frontal1 eth0: 192.168.0.2
frontal2 eth0: 192.168.0.3
heartbeat ip alias eth0:0: 192.168.0.1
frontal1 eth1: 192.168.1.1
frontal2 eth2: 192.168.1.2
My sotware are Debian 5.0 Lenny and heartbeat 2.1.3-6lenny4
I folowed the folow guides without any succes

Here you have my logs, commands result
When I do a BasicSanityCheck (2) I see a problem with IPaddr
But when I launch manualy the script Ipaddr ou Ipaddr2 the ip alias is created
and avaliable on the network.
I looked on a few forum about the subject, and I don't find any solution on my
problem
Thanks for your help
