IO operations becomes slow with NFSv4.1

Hi,

 

I have couple of machine mounted with nfsv4.1 from a FAS3250 on cluster mode.

The machines are hosting VMs which are running on the nfs mount.

 

It was working fine until some of the machine started to log

kernel: [703692.856028] Got error -10008 from the server on DESTROY_SESSION. Session has been destroyed regardless..

 

From the machine, the mounted nfs directory becomes slow (e.g cd in to directory or running ls -l command)

The VMs running in that host reports slow IO as well.

 

Just wandering if anyone has encountered such issue before with nfsv4.1

 

cheers,

Devendran
