Hi,
We need to update/reboot the NFS server on wich the hosted engine is
installed. This server also hosts a couple of extra storage domains (ISO,
Export and a iScsi domain). I'm wondering if this procedure is complete for
an oVirt 4.0 installation :
1-set the environment to global maintenance
2-set the extra domains to maintenance mode
3-shutdown the hosted engine
4-update/reboot the storage server
5-reboot the hosted engine
6-reactivate extra domains
7-disable global maintenance mode
I'm wondering what's happening after step 4 and how ovirt will react when
the NFS storage disapear and come back.
ovirt-ha-agent will try to reconnect the shared storage if hosted-engine
for all the time; depending on different factors, sanlock will fail
updating the hosted-engine lease ans this can bring the watchdog to reboot
the host.
Setting also local maintenance mode on the involved hosts is a good idea.
