We have 2 seperate Hyper-V Server 2008 R2 cluster sites. 1 with 3 hosts the other with 2. I will be using the site with only 2 hosts for examples.<br />
&nbsp;<br />
On all hosts we are seeing occassionally Disk and NTFS warnings when backups are occuring. Backup product is Commvault Simpana 9. Logs dont go back far enough for when we had DPM 2010.<br />
&nbsp;<br />
Disk warning example: EventID: 51, An error was detected on device \Device\Harddisk5\DR77 during a paging operation.<br />
&nbsp;<br />
NTFS error example: EventID: 137, The default transaction resource manager on volume \\?\Volume{ac774445-0d2e-1<wbr />1df-84ae-b<wbr />c1ce0b2974<wbr />3} encountered a non-retryable error and could not start. The data contains the error code.<br />
&nbsp;<br />
My question is Should we be concerned, they dont appear to be affecting backups? Also how do we determine what Harddisk5 is, we only have 3 cluster volumes on this site?<br />
&nbsp;<br />
Hope you can shed some light on this? Thanks Wes<br />

Hyper-V Cluster Host, Disk and NTFS Warnings\Errors

Microsoft Virtual Server was a virtualization solution that facilitated the creation of virtual machines on the Windows XP, Windows Vista and Windows Server 2003 operating systems. Virtual machines are created and managed through a web-based interface that relies on Internet Information Services (IIS) or through a Windows client application tool called VMRCplus. Features included Linux guest operating system support, Virtual Disk Precompactor, symmetric multiprocessing (SMP), x64 host operating system support, the ability to mount virtual hard drives on the host machine and additional operating systems support, including Windows Vista, and a volume shadow copy writer.
