VM storage fault (xene-pool1)
  • Monitoring
    Monitoring

    The fault has been mitigated and affected VMs are now back online.

    The VMs will have to be shut down again within a few days to replace a failed hardware component.

    Some users connected to VPN2 may be disconnected shortly as one of the VPN gateway servers needs rebooting even though it is still partially working.

    Besides this, please contact service-desk@cst.cam.ac.uk in case of any remaining problems.

  • Investigating
    Investigating

    Overnight a hardware fault took down the storage server that backs one of our main departmental VM pools (xene-pool1). All VMs running on that pool failed, which included the departmental database server, dbwebserver, Request Tracker, cl-student-ssh, part of the MSA service and the Windows Remote Desktop service.

    Investigating

    We are investigating reports that printing to legacy printers from Macs is currently disrupted, possibly due to a Bonjour problem. We suggest using DS-Print as a workaround.
