Cannot vMotion a virtual machine from an ESX/ESXi 4.1 host to an ESXi 5.0 host on NFS datastores (2009718)

  • 3 Ratings


  • Performing a vMotion on a virtual machine from an ESX/ESXi 4.1 to ESXi 5.0 host fails on NFS datastores.
  • The vMotion operation times out.

    Note: The percentage of progress at which the operation times out varies, but is seen to occur at 9% in some cases.

  • In the ESXi 5.0 VMkernel logs, you see the error:

    WARNING: NFSLock: NFSLockGetServerLock:2123: File is being locked by a consumer on host with exclusive lock.
    NFSLock: NFSLock_Acquire:2769: failed to get lock on file rhel4-6348faee.vswp 0x41000ba3e740 on ( Busy
    WARNING: Swap: vm 337820: OpenSwapFile:5664: Failed to open swap file '/vmfs/volumes/73857835-ab1391c7/workingdir/rhel4-6348faee.vswp': Busy
    WARNING: VMotionRecv: ResolveSwapType:1366: 1291081286682539 D: failed to find a valid swapfile.

    WARNING: VMotionUtil: VMotionStreamCheckForStreamKeepalives:727: 1291081286682539 D: failed to read stream keepalive: Connection closed by remote host, possibly due to timeout

  • You see NFS lock warnings similar to:

    WARNING: NFSLock: 2407: Cannot remove lockfile .lck-ee08000000000000 : I/O error
    WARNING: NFS: 1990: Failed to get attributes (I/O error)


This behavior is seen on NFS datastores if a Working Directory is defined or if the Swap file is not located in the home directory. It occurs due to the way in which ESX/ESXi 4.1 handles swap lock files.
