/work-common issues

We have to unmount /work-common from Hexagon because of HW issues with the /work-common MDS server.

We are working to fix this problem ASAP.

Update 21:35: We have moved MDS to one of the OSTs until MDS HW is fixed. The file system can have slightly degraded performance. It should be available on all compute nodes and login nodes, except login5. We are working to make it available on login5 as well.

Update 14.05 13:00 : /work-common is back on login5
