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