[Linux-cluster] need help with cluster

[Grisha G.]

Hi
I don't know if its the right address to send this mail to but I really need
help so I'm gonna try my luck anyway

I'm trying to configure a RHEL HA cluster with MySQl and GFS,

I have 2 virtual machines running centos5.2 virt1.xen and virt2.xen
on them I have sheared iscsi device with GFS2 that i want MySQL database to
be on.

I installed MySQL servers on both virtual machines, but I can't configure
the cluster service properly so it will be a HA MyQSL cluster

Please help I can't find any proper howtos about that.

I get this errors:
clurgmgrd[4070]: Stopping service service:MySQL
clurgmgrd[4070]: stop on mysql "mysql" returned 1 (generic error)
clurgmgrd: [4070]: Checking Existence Of File
/var/run/cluster/mysql/mysql:mysql.pid [mysql:mysql] > Failed - File Doesn't
Exist
clurgmgrd: [4070]: Stopping Service mysql:mysql > Failed
clurgmgrd[4070]: Marking service:MySQL as 'disabled', but some resources may
still be allocated!
clurgmgrd[4070]: Service service:MySQL is disabled

clurgmgrd[4070]: Service service:MySQL is disabled
clurgmgrd[4070]: Stopping service service:MySQL
clurgmgrd[4070]: stop on clusterfs "GFS" returned 2 (invalid argument(s))

This is my conf files:
# cat /etc/cluster/cluster.conf

# cat /etc/my.cnf
[mysqld]
datadir=/data
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid



# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6

hostname = virt1.xen

192.168.122.24 virt2.xen

all the conf file are the same on both virt machines

with this configurations the virtual machine didn't load after reboot it got
stuck on loading cman

I can't find any proper howtos on configuring the services and resources in
the cluster, and I realy need to do this

Thank for your help
