SOLVED: Synology DS1813+ with NFS VAAI does not work

Postby ctrlX » Tue Jun 23, 2015 7:50 pm

I have a Synology DS1813+ that is used as a datastore to my ESXi 6.0 host. The ESXi host has been installed with the NFS VAAI plugin from Synology. Reboot of the host has been performed after installation.

Code: Select all

[root@esxi1:~] esxcli software vib list | grep nfs
esx-nfsplugin                  1.0-1                                 Synology  VMwareAccepted    2015-06-23


Two of the NICs on the Synology NAS is used for NFS traffic and separated with their own IPv4 network and VLANs. This is also configured on the ESXi host.

Code: Select all

nas> ifconfig
eth2      Link encap:Ethernet  HWaddr [hidden]
          inet addr:10.0.13.5  Bcast:10.0.13.255  Mask:255.255.255.0
          inet6 addr: fe80::211:32ff:fe2e:d4ca/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

eth3      Link encap:Ethernet  HWaddr [hidden]
          inet addr:10.0.14.5  Bcast:10.0.14.255  Mask:255.255.255.0
          inet6 addr: fe80::211:32ff:fe2e:d4cb/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1


Code: Select all

[root@esxi1:~] esxcli network ip interface ipv4 get

vmk6  10.0.15.2     255.255.255.0  10.0.15.255     STATIC           false
vmk7  10.0.15.102   255.255.255.0  10.0.15.255     STATIC           false


VLAN separation is performed on my Cisco SG300-28 L3 managed switch.

Here are my mounted NFS datastores:

Code: Select all

[root@esxi1:~] esxcli storage nfs list
Volume Name                     Host       Share                   Accessible  Mounted  Read-Only   isPE  Hardware Acceleration
------------------------------  ---------  ----------------------  ----------  -------  ---------  -----  ---------------------
NFS-VLAN14-SATA3-Install_Media  10.0.14.5  /volume1/Install Media        true     true      false  false Not Supported     
NFS-VLAN14-SSD-VM_Datastore     10.0.14.5  /volume2/VM Datastore         true     true      false  false Not Supported     
NFS-VLAN13-SATA3-Install_Media  10.0.13.5  /volume1/Install Media        true     true      false  false Not Supported     
NFS-VLAN13-SSD-VM_Datastore     10.0.13.5  /volume2/VM Datastore         true     true      false  false Not Supported


As you can see, the NFS datastores are still listed as "Not Supported". If I perform a VM copy operation and monitor the logs with the following command:

Code: Select all

tail -f /var/log/vpxa.log | grep -i SynologyNasPlugin


I receive the following error message in the vpxa.log:

Code: Select all

SynologyNasPlugin: session request for 10.0.13.5 /volume1/Install Media /vmfs/volumes/8e924b00-481ad4ce NFS 1
SynologyNasPlugin: could not create RPC mount client for the remote host 10.0.13.5 error:: RPC: Program not registered


I have searched the forum for an explanation and Googled the error message without any results. Is there something I have missed? Any thoughts or suggestions would be greatly appreciated. Could the cause be the new ESXi v6.0? Although I did find a blog post that proved NFS VAAI plugin support on ESXi 6.0.

Re: Synology DS1813+ with NFS VAAI does not work

I found a setting in DSM that I thought would resolve my issue:

Storage Manager > Volume > selected the volume where my vSphere datastores reside > Configure > Advanced LUN > choose "8KB (Optimized for VMware VAAI)" from dropdown > OK.

This didn't resolve my issue either. Even tried rebooting both the ESXi host and my Synology DS1813+.

I must say I find it very strange that NFS VAAI does not work in my environment and I seem to be the only one in the world. As I have Googled for this issue for several days now without finding anything remotely close to an answer.

I am not far away from registering a support ticket at Synology as their product is supposed to support VMware integration.

Have you tried to reboot your VMware host? It is required to reboot the host to make NFS VAAI work.

Yes I rebooted the host several times. I have however found what was wrong! :D

I was going to create a new port group on one of my distributed switches when I received a very obscure error message. After some troubleshooting I noticed by accident that my distributed switches were running version 5.5, not 6.0. Reason being they were imported when I migrated from vCenter 5.5 to 6.0. After upgrading my dvSwitches to 6.0 I was able to create new port groups and the NFS VAAI plug-in started to work!

Lucky u!
On my DS415+ its still unsolved.
VAAI does not work when i try to create a new Harddisk. It takes a couple of minutes and there is traffic on the network.
When i do the same operation via ISCSI its just second and the disk has been created.
