What privaleges does the ESXi host require for NFS access?
Root privileges with Read/Write access (if deploying VMs to NFS)
No Root Squash must be configured by the NFS administrator on the NFS server.
What are the requirements for an NFS datastore?
- 1. Create a VMkernal paort
- 2. NFS Server Name/ IP address
- 3. Folder on the NFS server (i.e /lun1 etc.)
- 4. Mount as system read only (default: read/write)
- 5. NFS datasotre name:
You add an RDM to a VM on a NFS datastore, but the operation fails. What's the problem?
The VMkernal routes SCSI commands over RDM without modification, but NFS does not support SCSI commands on this interface. Instead, select a VMFS datastore for the location of the RDM's pointer files
What are the multipathing recommendations for NFS storage (assuming EtherChannel support on the external switch)
- a. one vmkernal port
- b. adapters attached to seperate switchs with nic teaming
- c. configure the nfs server with mulitilpe ip addresses
- d. nic teaming policy = ip hash load balancing policy
What are the multipathing recommendations for NFS storage (without EtherChannel support on the external switch)
- a. 2 or more vmkernal ports on different virtual switches on different subnets
- b. NIC teaming with adapters attached to the same physical switch
- c. configure the nfs server with multlple IP addresses even on same subnet
- d. allow VMkernel routing table to make decision on which link to send packets (require mulitpe datastores)
