Re: [OmniOS-discuss] Testing RSF-1 with zpool/nfs HA

If that's the case, perhaps you should check to see if the nfs ports are open upon failover. If they open just as quickly as the pings respond, then I would blame the nfs locking managers or nfs in general. The action to remedy that is beyond my scope other than to try force a remount
