Issue

  • Is VMFS backed VMDK disk images on VMWare guests supported by Red Hat Support for clustered filesystems such as GFS2?
  • Can I use VMDK disks with the multi-writer flag for GFS2?
  • Can I use VMDK disks as shared storage for my cluster?
  • I have 2 VMs running on VMware ESX Server, both connected through VCenter, need to know your best recommendation on configuring shared filesystem GFS on VMs?
  • Can I use clvm clustered LVM for managing shared storage on VMs running on VMware Hypervisor and part of High Availability Cluster?

Environment
