For 1. I was wondering if perhaps, we could have an option to specify the mount options. If I understand correctly, applying a soft mount instead of a hard mount would prevent this from happening. I'm however not sure of the implications this would have on the data integrity.. I would really like to see it happen in the ha-agent, as it's the one which connects/mounts the storage it should also unmount it on boot. However the stability on it, is flaky at best. I've noticed if `df` hangs because of another NFS mount having timed-out the agent will die. That's not a good sign.. this was what actually caused my hosted-engine to run twice in one case. > Thanks, > Bob > > >> I think wdmd or sanlock are causing the reboot instead of poweroff >> >> Joop >> >> _______________________________________________ >> Users mailing list >> Users@ovirt.org >> http://lists.ovirt.org/mailman/listinfo/users > > > _______________________________________________ > Users mailing list > Users@ovirt.org > http://lists.ovirt.org/mailman/listinfo/users _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
