.....
drbd0 was Primary at this time and on this node? ... this error
would
indicate that drbd0 was Secondary when Heartbeat tried to mount the
filesystem.
mmmm Do not heartbeat is responsible for that? Heartbear should
set as
Primary on this node...
You created the filesystem on /dev/drbd0 with DRBD 0.7 and now
upgraded
to DRBD 8.2 ... did you also made a migration of the meta-data to
and
tested DRBD without heartbeat?
I didnŽt made a migration, I did "create-md", however the
partition (data)
.... ok, "create-md" converts the 0.7 to 8.x meta-data. so you did
upgrade
(migration was the wrong term..) the meta-data ;-)
has not been formatted...
This is section resource:
<primitive id="drbd_mysql" class="ocf" provider="heartbeat"
type="drbd">
<instance_attributes>
<attributes>
<nvpair name="drbd_resource" value="r0"/>
</attributes>
</instance_attributes>
<operations>
<op name="monitor" interval="29s" timeout="10s"/>
</operations>
</primitive>
</master_slave>
<group id="rg_mysql">
<primitive class="ocf" type="Filesystem"
provider="heartbeat" id="fs_mysql">
<instance_attributes>
<attributes>
<nvpair name="device" value="/dev/drbd0"/>
<nvpair name="directory" value="/media/replica"/>
<nvpair name="type" value="ext3"/>
</attributes>
</instance_attributes>
</primitive>
...
<nvpair name="type" value="ext3"/>
</attributes>
</instance_attributes>
</primitive>
hmmm ... and your colocation and order constraints? drbd has to be
primary
before the filesystem is mounted and the filesystem has to be
mounted on the
primary node ... there is a good example ... if you really want to
go with a
Master/Slave configuration:
I have not said that the resources are members of a group. The
resource drbd is the first resource, therefore the order should is
correct.
i doubt this will work at all
if you're using type="drbd", then it needs to be a master/slave
resource.
otherwise neither node will be allowed to mount the filesystem.
http://www.linux-ha.org/DRBD/HowTov2
In this link has this example:
<master_slave id="ms-drbd0">
<meta_attributes id="ma-ms-drbd0">
<attributes>
<nvpair id="ma-ms-drbd0-1" name="clone_max" value="2"/>
<nvpair id="ma-ms-drbd0-2" name="clone_node_max"
value="1"/>
<nvpair id="ma-ms-drbd0-3" name="master_max" value="1"/>
<nvpair id="ma-ms-drbd0-4" name="master_node_max"
value="1"/>
<nvpair id="ma-ms-drbd0-5" name="notify" value="yes"/>
<nvpair id="ma-ms-drbd0-6" name="globally_unique"
value="false"/>
<nvpair id="ma-ms-drbd0-7" name="target_role"
value="stopped"/>
</attributes>
</meta_attributes>
<primitive id="drbd0" class="ocf" provider="heartbeat"
type="drbd">
<instance_attributes id="ia-drbd0">
<attributes>
<nvpair id="ia-drbd0-1" name="drbd_resource"
value="drbd0"/>
</attributes>
</instance_attributes>
<operations>
<op id="op-drbd0-1" name="monitor" interval="59s"
timeout="10s" role="Master"/>
<op id="op-drbd0-2" name="monitor" interval="60s"
timeout="10s" role="Slave"/>
</operations>
</primitive>
</master_slave>
If I put this, The cib response is something like: This code is not
a standar DTD...
it depends where you put it
it would certainly complain it you tried to add it to a group
Is very rarely....

Andreas
With DRBDv0.7 the partition was formatted with the type "ext3"
