All has been working fine until yesterday, when a network problem caused the GPFS scratch filesystem to die.
We were unable to  recover it and today we have rebuilt it from scratch:
ARC is still not working, but all gLite/EGI services are up and running.
This was an unscheduled downtime that will certainly affect A&R of this month.

Next week the grid cluster at CSCS enters a scheduled downtime.
We will move the hardware from the old building to the new datacentre
and introduce major changes in the infrastructure: new WNs to replace
old Sun Blades and new network design, we'll move from hybrid
ethernet/infiniband to all-infiniband. The downtime should last no longer than 3 weeks.
  • PSI
  • Switch (Alessandro Ussai)
