Hi all, Hopefully this is the correct place to ask this, if not, my apologies.
On a CS 3.0.2 setup using KVM on RHEL6 and NFS as primary storage, we noted some strange behaviour when it comes down to the NFS mount options for the primary storage. When a hypervisor is booted, the primary storage is mounted using the default mount options as configured in /etc/nfsmount.conf. However, when we shutdown the agent, manually unmount the primary storage and start the cloud agent again, the primary storage is mounted using some hardcoded values (in our case the NFS mount becomes a soft mount, in stead of hard and the timeo and retrans settings change). After some digging, we found that the script /usr/lib64/cloud/agent/scripts/vm/hypervisor/kvm/kvmheartbeat.sh is responsible for that (the mountoptions are hardcoded there). My question is: what's the reasoning behind this? Is this a bug or leftover? Or is this by design and if so, why are these settings now always enforced? Thanks in advance for any insights and your time. Best regards, Roland Kool | Sr. Systems Engineer | TomTom TechOps |
