  • 1.  Vm-rhel5 gpfs without rdm

    Posted Jun 13, 2012 10:10 AM

    hey guys, anyone knows or tried to configure IBM GPFS for linux on several linux RHEL5 vms ?

    My systems are on vSphere 4.1 u1, no local storage on the hosts.

    I don't want to use DRM,

    any ideas  ?

    Hello,

    I would appoarch this like any other shared disk cluster. In general shared disk clusters need to use Raw Disk Maps for the shared disks but they do not have to be created that way. Given that this is in essence a Linux cluster as well, you may have to use a Linux fence mechanism as well. This depends on how many cluster services you require.

    Thank you , I will try to do that , although the problem is first connecting to the shared disk , since I cannot add RDM to my env.

    Hello,

    It is possible to use standard VMDKs in a shared disk virtual machine cluster. There is a great document on how to do this for a Microsoft Cluster, I would follow similar steps for GPFS unless IBM has something specific.

    Hello,

    In this documentation, it's explain that you must use RDM for VMs host on different physical ESXi

    So for me, you can't use VMDK shared for it.
