Hi I understand the convenience of NFS, however in NFS, filesystem is at Storage end, and the CPU , RAM performance of Storage become very very important . The Overload may happen on storage rather compute/hybervisor.
Where as iscsi based sharedmountpoint might have more efficiency for this. I am facing issue is , i create first host with sharemoutpint /vmdisk , there is no issue of this, After that i add another host the the Cluster, and and I mount the same name of ShareMountPoint (/vmdiak) in the newly added host , since /vmdisk already appear in Primary Storage , and is in "Cluster" , so I did not create it again . I assume this shall work but apparently the /vmdisk in newly added in hypervisor host is not recognizable. .
