[OmniOS-discuss] Loosing NFS shares

[Oliver Weinmann]

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
