Hello,
I'm having difficult configuring my HA to use DRBD. I have followed all
the instructions on the LinuxHA website and got DRBD up and running.
I'm at the point where I need to create a resource in the CIB for DRBD
but I'm at a loss on how to accomplish this. I read through the
archives and found some configs people were using to accomplish what I'm
doing but it doesn't appear to be working.
My DRBD configuration:
resource ha {
protocol C;
startup {
wfc-timeout 0;
degr-wfc-timeout 120; # 2 minutes.
}
disk {
on-io-error detach;
}
syncer {
rate 10M;
group 1;
al-extents 257;
}
on ipt01-node01 {
device /dev/drbd0;
disk /dev/sda6;
address 10.25.118.71:7788;
meta-disk internal;
}
on ipt01-node02 {
device /dev/drbd0;
disk /dev/sda6;
address 10.25.118.72:7788;
meta-disk internal;
}
}
The resource configuration I'm trying in the CIB:
<group id="shared_storage01">
<primitive id="shared_storage" class="heartbeat"
type="drbddisk" provider="heartbeat">
<operations>
<op id="shared_storage_mon" interval="120s" name="monitor"
timeout="60s"/>
</operations>
<instance_attributes id="ias_shared_storage">
<attributes>
<nvpair id="shared_storage_attr_1" name="1"
value="sip-shared"/>
</attributes>
</instance_attributes>
</primitive>
<primitive id="shared_filesystem" class="ocf" type="Filesystem"
provider="heartbeat">
<operations>
<op id="shared_filesystem_mon" interval="120s"
name="monitor" timeout="60s"/>
</operations>
<instance_attributes id="ias_shared_filesystem">
<attributes>
<nvpair id="shared_filesystem_device" name="device"
value="/dev/drbd0"/>
<nvpair id="shared_filesystem_directory" name="directory"
value="/share"/>
<nvpair id="shared_filesystem_fstype" name="fstype"
value="ext3"/>
</attributes>
</instance_attributes>
</primitive>
</group>
I'm also confused on which OCF/LSB script to use. I copied the drbddisk
script in drbd-source/scripts to /usr/lib/ocf/resource.d/heartbeat and
/etc/ha.d/resource.d. I'm not sure if this is the correct resource
script to use. I have seen poeple using 'datadisk' but I do not know
where to find that at.
drbd-0.7.21
heartbeat-2.0.7
RedHat EL4 2.6.9
Any help would be greatly appreciated, thank you!
