xpenology supply NFS to esxi 7 datastore?

[mervincm]

Is anyone using xpenology to supply NFS for esxi 7?

I was not able to make it work. It does work as expected on my real Synology 1815+ running DSM beta 7.0, but no matter what I tried I could not get the esxi host to add a datastore on the XPEnology NAS. I can use nfs v3 and v4 to my real synology.

 

 if you are able to make it work I would appreciate some feedback.

I have configured an NFS mount accessed by ESXi on XPE DSM in the past, and it works fine, but I haven't tried explicitly to use it as a datastore.  What errors do you get?

[mervincm]

I am trying to use remote/shared storage to facilitate vmotion between two esxi hosts. thus I am trying to mount an NFS share hosted on my XPE box as a datastore on both of my hosts. I believe I worded that correctly, but I admit that I don't understand your comment as I don't understand how else esxi can access an NFS share.

 

Xpenology side

Control Panel - file services, NFS and NFS4.1 checked to enable. NFS advanced settings at default.

Control Panel - shared folder, created a share "NFS" NFS Permissions, added 2 entries, one for each host, by single IP, Read/Write, squash>no mapping, Asyncronous>Yes, Non-priv port>Denied, Cross-mount>Allowed

Control Panel, Info Center, service, confirmed NFS enabled and firewall exception in place. 

 

vmWare side

html5 client login as root to the esxi host

navigate to storage - datastores - click new datastore

NFS 3 , or NFS 4 (tried both)

I previously did a scripted NFS mount on ESXi.

 

I tried all the above except didn't bother with a firewall exception and was able to mount a test NFS datastore using either V3 and V4 protocols.

Thank you for testing! I used a 918+ image, same for you? I will build a test NAS on the weekend.

 

 

[mervincm]

I have not had any luck yet. I wonder if it is an issue with 918+?

I have not been able to scare up any spare hardware to build a test xpenology yet either

This issue is bewildering to me.

I built a test xpenology system and it worked first try.

I tried it on my main system once again, and it worked this time. I moved over a couple VMs to NFS storage on my main system, and everything is working perfectly. A week later I go to use a VM and it has read errors and cannot be restarted. sure enough, the NFS share is no longer available to vsphere and can not be re-established.

I didn't change any network config, nor NFS share permissions, nothing at all on vsphere or synology that I can recall.

I can still connect to the same NFS share from my backup synology, so the share is actually available, I just can't use it from vsphere .....
