If you are deploying CloudStack with XenServer and NFS the system will force sync by default for primary and secondary storage. This is the default option for XenServer. Not sure how it is trated for VMware and KVM. Regards,

Hello, All cloudstack documentation prepares the NFS share using async, why not use sync for better data protection? Has anyone used NFS shares with sync? what would be the drawbacks if any? Thanks for your valuable responses. Amin
