Hi Folks!
I have to troubleshoot a new installed MSCS2012r2 on ESXi5.5 (MSCS on different boxes)
We use as storage vendor netapp in a FC environment.
The system disk of each Windows2012r2 is based on a vmdk file. The other partitions (quorum, MSDTC, data) are build up on raw device mappings.
The LUN type for the raw device mappings on the netapp is Windows2008 or later.
On the MSCS nodes in the eventlog following Warnings frequently appear:
Event ID: 50 NTFS Warning{delayed write failed} Windows was unable to save all the data for the file. The data has been lost. This error may be caused by a failure of your computer hardware or network connection.Please try to save this file elsewhere
Event ID: 140 NTFS WarningThe system failed to flush data to the transaction log. Corruption may occur in VolumeId:<> DeviceName: \Device\HarddiskVolume ({device busy} The device is busy at the moment)
Event ID: 153 Disk
The IO operation at logical block address “” for Disk “” was retried.
The case is also by netapp and vmware but they have no ideas at the moment. The ESX and the netapp environment works fine for other clusters based on W08r2.
