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.

Is your backdone using 10Gbe network and are they setup with redundancy (eg. MLAG)? Regards.

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.
