Subject Automatic KVM host reboot on Primary Storage failure
Date Fri, 14 Nov 2014 16:07:28 GMT
Hi guys,

I'm wondering why us there a check
inside /usr/share/cloudstack-common/scripts/vm/hypervisor/kvm/kvmheartbeat.sh
?

I understand that the KVM host checks availability of Primary Storage, and
reboots itself if it can't write to storage.

But, if we have say, 3 NFS in a cluster, then lot of KVM hosts - 1 primary
storage going down (server crashing or whatever) - will bring porbably 99%
of KVM hosts also down for reboot ?
So instead of loosing uptime for 1/3 of my VMs (1 storage out of 3) - I
loose uptime for 99%-100% of my VMs ?

I manually edit this script to disabled reboots - but why is it there in
any case ?
It doesn't make sense to me - unless I'm mising a point (probably)...

Thanks,
