Tank you for the quick anser
Im tryng to make a cluster using pacemaker on OpenSUSE 12.1 with DRBD +
OCFS2 + Mysql on top of the filesystem.
The system will have two DRBD resources to be mounted on /var/lib/mysql
and on /export.
Be sure you configured "resource-and-stonith" fencing policy for DRBD
and you use a correct fencing script like: goo.gl/O4N8f
I have configured it this way
stonith-enabled="false" \
Bad idea! You should really use stonith in such a setup ... in any
cluster setup.
Itd disable while im getting the cluster to mount the filesystems
colocation col_ocfs2 inf: .......
Use "crm configure help colocation" to find out more, the same for order.
You could also add the two file system primitives to the cl_ocfs2_mgmt
group, then only the constraints between this group and DRBD are needed.
Regards,
Andreas
I was not abble to get any of the partitions mounted, I tought there was something very bad on my
configuration
and changed it to resemble the configuration showed on
http://www.clusterlabs.org/wiki/Dual_Primary_DRBD_%2B_OCFS2 and try to get at least one of the
partitions mounted.
Now this is my running configuration:

I commited the configuration to see if I would end up with the /export mounted, but no luck on this
too.
then I stopped the pacemaker on both hosts and started it just on jupter. The filesystem did not get
mounted.and taking a look at the /var/log/messages i could see this entries:

But looking back on the log give no clues. Then I started the pacemaker on the second host and took
a look at the log, then i found this:

The weird thing is at this line:
Mar 21 10:28:13 artemis lrmd: [2429]: info: RA output: (resFSexport:0:start:stderr) FATAL: Module
scsi_hostadapter not found
Why pacemaker is looking for a scsi device since it is configured to use DRBD?.
Please, can someone shade a light over this?
Regards,
Carlos
