Dear all,
I’m using NFS system datastore for my setup. The FreeNAS provide this NFS system. But one day, NFS server crash and hang, need to hard reboot. At the time NFS is hang, the vm is still running (linux & windows vm). When NFS server is back, Linux VM remount the disk on NFS as read-only and need to restart the vm and do check disk to fix error before run again. The problem is there are some vm cannot fix the disk correctly, so that it get error and cannot boot anymore.
So is there a way to make opennebula auto stop the vm if detect NFS server is down or the way to ensure the system running safely of NFS has to restart
Thank you all
