Due to a SLES 12 filesystem issue, all Lou SLES 12 systems are unavailable. We are working with our vendor to resolve this issue. In the meantime, please note:

• You can use the following Lou front-end nodes (LFEs), which have been downgraded to SLES 11: lfe3, lfe4
• Post-processing work is not permitted on the LFEs. Please note that any such process running on lfe3 or lfe4 might be killed.
• The Lou Data Analysis Nodes (LDANs) will remain unavailable until this issue is resolved.
• The shiftc utility has access to two SLES 11 data transfer nodes, so we recommend using shiftc to transfer all data. Set the --hosts=NUM option to a number greater than 1 to ensure that shiftc uses the SLES 11 nodes.

For more information about using shiftc, see the following Knowledge Base section:

• Using Shift for Local and Remote Transfers

We apologize for the inconvenience and appreciate your patience. Watch for a status update on Tuesday, May 29.
