right, Paul ... this might be a good suggestion ... How could we bring it to 
the developers?

Just to give some background (as I asked the same questions years ago). *IF* 
you only have one shared storage pool per cluster (and no local storage) and it 
goes wonky, then most likely fix is to restart the host(s). The VMs have 
already crashed because the primary storage is disconnected and the host is 
unable to reconnect it.

That’s why it reboots.

As everyone who has a cloud larger than their laptop knows, it also nukes the 
good VMs on other storage pools and local storage.

A global setting which allows operators to choose the behaviour they want might 
be a solution?

So ... found some information about this ... looks like this is an annoying 
problem (bug), which isn't going to be fixed ... But at least there is a 
possibility to change the behavior modifying the script

Thanks a lot, guys ..

Hi

As Lucian said , you can edit the script and remove the reboot , but
yes this is the normal behaviour of the script

You can modify the script to not reboot, but until we find a better way to deal 
with it this is correct behaviour. It sucks it reboots VMs on healthy storage 
though.

Subject: Re: Self-fencing when storage not available Hi Glenn,

we use KVM ... I also found the script:
/usr/share/cloudstack-common/scripts/vm/hypervisor/kvm/kvmheartbeat.s
h

Just wondering if we can avoid rebooting ...

Thanks

Hi Vlad,

Can I ask what hypervisor are you using?
The default action is to reboot the hosts

This is done in the heatbeat file on xenserver
/opt/xensource/bin/xenheartbeat.sh

Thanks
Glenn

4.7.0 source not available on any mirror

[Drew Gingery]

I haven't tried every mirror, but it doesn't seem top be present. There is
a 4.7.1 tarball out there, but it doesn't seem to be working very well for
me.

What should I consider the proper version for a new install?

Tempted to try 4.6.2
