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.</span></p>

<p class="MsoNormal"><span lang="EN-US">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.</span></p>
