I'm very new to clustering linux. I currently have SLES11 SP3 for vmware with the HA extensions installed on ESX 5.1 trying to use a Raw Device Map disk.

The RDM is in physical mode on a paravirtual SCSI controller with the SCSI bus mode = physical.

I'm trying to setup the disk using ocfs2 but I'm having trouble getting it setup. I have partitioned it as a primary without formatting it. So it now can be referenced as /dev/sdc1.

I created the SBD as this device, stonith is running. Then I try to format the drive using mkfs.ocfs2 /dev/sdc1 and it blows up.

I'm I doing something in the wrong order?

any help would be great.
