Hello,
at the moment I'm building a new HA-Cluster (Active-Active) with 2 servers
in the DMZ. The server has 5 NIC, 2 for the LAN in the DMZ , 2 for
heartbeat and DRBD and 1 unconfigured.
It is possible to configure 2 IP-adresses in the drbd.conf for 2 transport
channels? Now all data are going over only 1 NIC.
My /etc/drbd.conf:
resource drbd0 {
protocol C;
incon-degr-cmd "echo '!DRBD! pri on incon-degr'";
startup { wfc-timeout 0; degr-wfc-timeout 120; }
disk { on-io-error detach; } # or panic, ...
syncer {
group 0;
rate 12M;
}
on bgstsapdmz1 {
device /dev/drbd0;
disk /dev/mapper/sap_vg-sap_proxy;
address 11.0.0.2:7788;
address 11.0.0.3:7788;
meta-disk internal;
}
on bgstsapdmz2 {
device /dev/drbd0;
disk /dev/mapper/sap_vg-sap_proxy;
address 11.0.0.5:7788;
address 11.0.0.6:7788;
meta-disk internal;
}
}
resource drbd1 {
protocol C;
incon-degr-cmd "echo '!DRBD! pri on incon-degr'";
startup { wfc-timeout 0; degr-wfc-timeout 120; }
disk { on-io-error detach; } # or panic, ...
syncer {
group 0;
rate 12M;
}
on bgstsapdmz1 {
device /dev/drbd1;
disk /dev/mapper/sap_vg-bussiness_connector;
address 11.0.0.2:7789;
address 11.0.0.3:7789;
meta-disk internal;
}
on bgstsapdmz2 {
device /dev/drbd1;
disk /dev/mapper/sap_vg-bussiness_connector;
address 11.0.0.5:7789;
address 11.0.0.6:7789;
meta-disk internal;
}
}
Im using static routes for this net:
