• Final 5 servers have been deployed into lhcbRawRdst
• Draining improvement workaround by putting full or almost full disk servers in to Read Only
• 2-1-14-14 castor upgrade priority dropped as we have a draining workaround. Revisit once SL6 work done (in new year)

Operations Problems

• gdss720 / gdss763 are both drained, out of production and waiting for Fabric work on (poss RAID and other work)
• A few CMS SUM test failures this week, investigations inconclusive

Blocking Issues

• grid ftp bug in SL6 - stops any globus copy if a client is using a particular library. This is a show stopper for SL6 on disk server.
