Node status: Faulted

[MelvinCheung]

Hi everyone,

We had a power outage and one of our TrueNAS system is not coming back online. This is a 2-node Z35 (I believe) system in HA mode.
When executing hactl the node status is faulted:

root@truenas# hactl
Node status: Faulted
Node serial: xxxxxx
Other node serial: yyyyyyy
Failover status: Enabled
root@truenas:~ #

The webgui says:
HA is enabled.
Failover is in an error state.

Any help would be appreciated.
Regards.
