Hello I'm really sorry to disturb you but I have some questions:
I installed RedHat Clustering Suite and I have this configuration:
/etc/sysconfig/ha/lvs.cf
#Seccion General
primary = XXX.XXX.XXX.XXX
backup = 172.22.21.132
backup_active = 0
keepalive = 2
deadtime = 10
heartbeat_port = 1050
rsh_command = rsh
network = nat
nat_router = 172.22.21.254 eth1:0
# Per-virtual-server section
virtual httpcluster {
address = XXX.XXX.XXX.XXX eth3:0
active = 1
load_monitor = ruptime
timeout = 10
reentry = 10
port = 80
send = "GET / HTTP/1.0\r\n\r\n"
scheduler = wlc
pmask = 255.255.255.255
protocol = tcp
# Per-real-server section
#server rs1 {
# address = 172.22.21.133
# active = 1
# weight = 2000
#}
server rs2 {
address = 172.22.21.21
active = 1
weight = 1000
}
server rs3 {
address = 172.22.21.130
active = 1
weight = 1000
}
}
virtual wildfirecluster {
address = XXX.XXX.XXX.XXX eth3:0
active = 1
load_monitor = ruptime
timeout = 10
reentry = 10
port = 5222
scheduler = wlc
pmask = 255.255.255.255
protocol = tcp
# Per-real-server section
server jb1 {
address = 172.22.21.22
active = 1
weight = 1000
}
}
#Generacion de roundrobin para postfix
virtual postfixcluster {
address = XXX.XXX.XXX.XXX eth3:0
active = 1
load_monitor = ruptime
timeout = 10
reentry = 10
port = 25
scheduler = wlc
pmask = 255.255.255.255
protocol = tcp
send = "EHLO Cluster\r\n"
# Per-real-server section
server rs1 {
address = 172.22.21.130
active = 1
weight = 1000
}
server rs2 {
address = 172.22.21.21
active = 1
weight = 1000
}
}
I start it by initializing service pulse.

My cluster.conf is very small and simple since this was a testing cluster.
[root@venus ~]# more /etc/cluster/cluster.conf

and when I do clustat I get:

When I mount GFS i get:

And it mounts perfectly using mount -t gfs -oacl /dev/sdd1 /home (this is
an iscsi partition that I made GFS)
But apparently a consultant is telling me that this is not a cluster, and
that a director is not installed and that this is not a cluster and I can
see that even GFS telling me taht is joining a cluster so I'm really
confused.
Could you please tell me if this is a cluster? as far as I can tell I have
a quorate and GFS mounts the stuff and clustat returns a cluster, please
tell me if this is a cluster or not in your expert opinion.
Thank you for your time.
