How to increase the default maximum number of NFS mounts on ESX/ESXi hosting the default maximum number of NFS mounts on ESX/ESXi hosts

Details

This article describes how to change the default value for the configuration parameter that defines the maximum number of NFS mounts on an ESX/ESXi host.
 
Specifically, this article discusses: 
  • Configuring NFS TCP and NFS HEAP settings
  • Identifying settings that TcpIpHeapSize or TcpIpHeapMax must have

Solution

Default configuration allows for only eight NFS mounts per ESX host.
 
To change the default value for maximum NFS mounts on an ESX host:
  1. Connect a vSphere Client to a vCenter Server or a host.
  2. Select the host from the inventory panel and click Advanced Settings on the Configuration tab.
  3. In the Advanced Settings dialog box, select NFS and set NFS.MaxVolumes to 32 (64 for versions 4.x).
  4. Select Net and set Net.TcpIpHeapSize to 30 (32 for versions 4.x).
  5. Select Net and set Net.TcpIpHeapMax to 120 (128 for versions 4.x).
  6. Reboot the ESX host.
Note: These settings enable up to 32 (64 for versions 4.x) mounts on the ESX host.
