[RHEV] Intermittently some VMs when booting stop at grub prompt

Solution Unverified - Updated -

Issue

  • After logging block errors booting VMs stop at grub> prompt.
  • Can see boot device (hd0 - hd1 and hd2 are not partitioned) but grub appears to not be able to find any files in the /boot partition for the systems.
  • One thing in common they share two virtual drives.
  • It seems if the drives are removed from the VMs the problem goes away
  • It is unknown how the shared drives are used.

Environment

  • Red Hat Enterprise Virtualization 3.1 Hypervisor
  • Red Hat Enterprise Linux 6 Update 4 Guests
  • The storage luns for the VMs appear to be via a lefthand iSCSI array.
