Windows 2012 R2 Host crash frequently MPIO

[pmillart]

Hi All,

I have a Windows 2012 R2 (64bit) server Host

Details:
blade DELL poweredge M1000e
DELL M620 ; BIOS 2.2.7 ;
CPU : 2 x Intel(R) Xeon(R) CPU E5-2620 v2 @ 2.10GHz
Total memory : 96.0 GB
Disk San 500 Go ; Baie EMC VNX5400.
Module MPIO ; multipathing : Round Robin
Last patchset installed


This server only host One VM with Oracle Linux 6.7 64bits (bigdata lite 4.2.1 ) using bridged network.

on the message log, it seems that the issue is due MP I/O.
Do you have any recommandation on what can I do be more stable ?

Best Regards,

That looks like you have problems with your disks (which is not something we can help you with).

I can't make out anything about why the host "unexpectedly rebooted". Can you? If the host crashed, do you have any minidumps or other diagnostic data?

[pmillart]

Hi Michaln,

Thank you for your quick answer.
I try to figure out what can I do:

The Windows admin server just did the following steps:
- Memory Diagnostic => OK
- Remove unused pilote from bios (meszzanine card)
- stop auto restart on system failure.
- Windows Update ( 13 correctifs installed)
- Server has been restarted with diagnostic mode

Can I change something from virtualbox side to have mode informations ?
Can we change how VBox is doing I/Os ( today the VM storage is not using I/O cache)

[michaln]

You should already have VBox.log file(s) for the running VM.

You can change the VirtualBox I/O mode but I don't see why it should make any difference. The information showed previously strongly hints that you have bad disks in the system or possibly a faulty RAID controller. Testing memory and tweaking VirtualBox won't fix that.

[pmillart]

I have uploaded the log files from vbox.
But as you said earlier the server seems to crash when we are trying to access the files at some time.
I didn't find anything usefull on the logs to troubleshoot. Upload it just in case.

Thanks again for your help.

Regards,
Patrick

Indeed, nothing useful/suspicious in the VirtualBox logs.
