If the ESXi host has network connectivity issues during boot time, the NFS mount process may time out during the spanning tree protocol convergence. Compared to iSCSI and FC, NFS is relative easy to design, configure and manage. To ensure interoperability with all versions it is recommended that you reduce the maximum Client and Server version. Connected to a decent (Cisco) switch with higher system MTU NFS works just fine to QNAP and Synology NAS. http://qaisoftware.com/unable-to/failed-to-create-component-ultragrid.html
Here, select "Use the following IP settings" and enter a unique IP address and your network's subnet mask: Next, click the "Edit" button and enter your network's default gateway: You are When using NFS 4.1 you will not run into this problem.

However I can attach this ALL my other ESXi hosts successfully.I had this feeling that something was corrupted on my ESXi installation, and I just happened to be running resxtop on This policy needs to be enforced by the storage/server because ESXi does not prevent mounting the same share through different NFS versions. Thanks! ESXi 5.5 fails to restore NFS mounts automatically after a reboot (KB 2078204) Symptoms · Rebooting an ESXi 5.5 host reports the NFS datastore that it uses as disconnected. · The

Nfs Host Not Connected Idbi This blog post will give an overview of deployment considerations and best practices for running with Network Attached Storage in your VMware environment. Most storage vendors will support some form of link aggregation, although not all configurations might conform to the generally accepted IEEE 802.3ad standard. Tommy Good Article!!
The current version of ESXi 6.0 can hold 256 if adjusted. Go Here And a rescan completes about 3 to 4 times faster.

This provides better overall network performance and link redundancy. Call "hostdatastoresystem.createnasdatastore" For Object "ha-datastoresystem" On Esxi Your Turn What are your experiences with VMware in combination with NFS storage? Test your MTU with vmkping -s 1500 [IP of NFS server] cam A different issue I had was the NFS server (QNAP NAS) didn't have the NFS permissions for the VM
Running ESXi 5.5 below Patch 5? After unmounting all the datastores, during the remounting process, I happened upon a single NFS volume that would produce this issue, while 2 other volumes on the same filer had no So if you use Nexus switches make sure those ports connected to the ESXi servers and to the Storage array are configured correctly. this contact form I verified permissions on the volume, verified the NFS client settings, etc… finally, the issue was resolved by rebooting the VMHost.
All NAS-array vendors agree that it is good practice to isolate NFS traffic for security reasons. Datastore Settings The default setting for the maximum number of mount points/datastore (NFS.MaxVolumes ) an ESX server can concurrently mount is 8. If you increase max NFS mounts above the default setting of 8, make sure to also increase Net.TcpipHeapSize as well. Have you tested simply pinging the VMkernel IP address from the Veeam server?
