Hi,
I would like to submit to the community the issue below.
We are experiencing troubles with a NFS shares running on a Windows 2008 R2 standard system.
The server is used as a storage server for VMs running Linux.
All the VMs' virtual disk files are stored on the Windows system that runs NFS services.
All goes well for a while: all VMs run and can access data on the NFS share. Data can be read and written on the storage with no issues.
This goes okay for about a week and then suddenly all VMs & VMs hosts loose connection to the Windows 2008 NFS server (at the same time) and crash down.
The only way to get access again to the NFS share is to do a hard reset on the Windows system (stopping the NFS service doesn't work - on restarting Windows the server just hangs).
Once the Windows server comes back up again all is well and VMs can be run again.
Going through the NFS logs on the server only show read and writes before the crash. The System logs aren't showing anything particular.
We got the hardware supplier to check the system: they didn't find anything wrong.
Has anybody experienced this situation? Any ideas on how to resolve this?
This has a big impact for us as a whole group can't work when the systems have crashed.
Any help or suggestion would be much appreciated.
Regards.
