Event ID: 5120
Source: Microsoft-Windows-FailoverCluster
Level: Error
Description: Cluster shared volume “volume_name” is no longer available on this node because of “STATUS_BAD_NETWORK_PATH(c00000be)’. All I/O will temporarily be queued until a path to the volume is re-established.

Event ID generated: 5142
Source: Microsoft-Windows-FailoverCluster
Description: Cluster Shared Volume ‘Volume_name’ (‘Cluster Disk #’) is no longer accessible from this cluster node because of error ‘ERROR_TIMEOUT(1460)’. Please troubleshoot this node’s connectivity to the storage device and network connectivity

When accessing a CSV volume from a passive (non-coordinator) node, the disk I/O to the owning (coordinator) node is routed through a ‘preferred’ network adapter and requires SMB be enabled on that network adapter. For SMB connections to work on these network adapters, the following protocols must be enabled:

  • Client for Microsoft Networks
  • File and Printer Sharing for Microsoft Networks

Mit anderen Worten: der gesamte Netzwerk-Traffic aller Hyper-V-Server eines Clusters geht durch den aktuellen Owner des iSCSI-CSVs… m(

Steve Jobs zu MobileMe

Steve Jobs’ eMail an seine Entwickler über die Fehler bei der MobileMe-Einführung:

Team,

The launch of MobileMe was not our finest hour.  There are several things we could have done better:

– MobileMe was simply not up to Apple’s standards – it clearly needed more time and testing.

– Rather than launch MobileMe as a monolithic service, we could have launched over-the-air syncing with iPhone to begin with, followed by the web applications one by one – Mail first, followed 30 days later (if things went well with Mail) by Calendar, then 30 days later by Contacts.

– It was a mistake to launch MobileMe at the same time as iPhone 3G, iPhone 2.0 software and the App Store.  We all had more than enough to do, and MobileMe could have been delayed without consequence.

We are taking many steps to learn from this experience so that we can grow MobileMe into a service that our customers will love.  One step that I can share with you today is that the MobileMe team will now report to Eddy Cue, who will lead all of our internet services – iTunes, the App Store and, starting today, MobileMe.  Eddy’s new title will be Vice President, Internet Services and he will now report directly to me.

The MobileMe launch clearly demonstrates that we have more to learn about Internet services.  And learn we will.  The vision of MobileMe is both exciting and ambitious, and we will press on to make it a service we are all proud of by the end of this year.

Steve
