With ESXi 6.0 I have had NFS problems as well. You should use at least
6.0U2(or 6.5.0d with the 6.5 line)
Another problem may be timeouts. ZFS will wait longer for a disk than
ESXi for NFS. What you can do is reducing disk timeout time in
/etc/system with set sd:sd_io_time=0xF (=15s, default is 60s). Check
system-logs for disk related problems (/var/adm/messages).
You should also use vmxnet3s for OmniOS with increased buffer settings
for vmxnet3, tcp and NFS for 10G networking.Snaps and replication itself
are uncritical as long as you do not have disk or network problems. Ex
MTU 9000 can give problems. Enough RAM may be another item. You should
give 8GB or more to OmniOS.

Hi,
We have a hyperconverged setup.
ESXi 6.0 -> OmniOS VM -> Storage Passthrough. The 10GB Nics are in
configured in Active / Standby. For NFS I use a dedicated /24 VLAN.
I wonder if ZFS replication or snapshotting could be the reason for
the problems we are seeing. The system fails at night time. We have
several auto-sync jobs from a Nexenta system to this system. I have
now disabled these jobs. I just wonder where logs etc. I can find any
information on what is going on on the system when it fails.
The symtoms are always the same. The vmware nfsshare disappear. So I
just reshare them (nfs set nfsshare=…. /hgst4u60/vmware-ds-1. Then the
root ZFS folders of all local drives that I think have snapshots
enabled are unmounted. So I have to unmount them all hard and remount
them. Also the root ZFS folders from replicated ZFS folders are
unmounted. This is why I assume that there is a link between the
problems and auto-sync or snapshotting.

Hi Oliver,
What is your network setup in relationship to NFS file server and VM
Host? Is your backdone using 10Gbe network and are they setup with
redundancy (eg. MLAG)?
Regards.

Hi,
we are using OmniOS for a few months now and have big trouble with
stability. We mainly use it for VMware NFS datastores. The last 3
nights we lost all NFS datastores and VMs stopped running. I
noticed that even though zfs get sharenfs shows folders as shared
they become inaccessible. Setting sharenfs to off and sharing
again solves the issue. I have no clue where to start. I’m fairly
new to OmniOS.
Any help would be highly appreciated.
Thanks and Best Regards,
Oliver
