In your vmware environment you have created a nfs datastore but when you are trying to copy files to it, you lost the connection.
You can check the file vmkernel.log that you can find in your esx host in :
You should find these lines of error :
Lost connection to the server xxx.xxx.xxx.xxx mount point /yourdatastorefolder mounted as ........... ("yourdatastorename") Restored connection to the server xxx.xxx.xxx.xxx mount point /yourdatastorefolder mounted as ........... ("yourdatastorename")
vmnic3: 4026 bytes packet couldn't be sent (mtu=1500)
vmnic3: oversized tsoMss: 8948, mtu=1500
As explained in vmware documentation you have to check communication with your nfs datastore. So using , for example Putty over ssh, you can :
Ping your nfs datastore
Find your vmkernel network card :
In the output you can see the MTU value of your network card and which is the vmkernel network card. Now you can ping your datastore using the network card, trying different MTU values :
vmkping -I vmk1 -s 1420 xxx.xxx.xxx.xxx
You probably need to change the MTU of your esx host’s network card. Maybe you have an MTU set to 9000 and you need to set it to 1500.
Using the vsphere client : Configuration – Networking. Select vmkernel network card and select “Properties” . Select “Vmkernel” and click on “Edit” :
You will be able to see the new MTU value using the previou command :
Click on the Virtual Machines on the left panel; click with the right mouse button. In the Menu – Autostart, set “Enabled”.
Repeat for all the vm where you want the autostart
Click on “Virtual Machines2 label on the left panel. On the right panel, you’ll see a table with your vms. You can add autostart information by right-clicking column header > Select Columns. Check Autostart order.
Click on the Virtual Machines on the left panel; click with the right mouse button. In the Menu – Autostart, you can see and set to start later or erlier.
