Hello All, I wish to propose Shared NFS Zone-wide (primary) Block Storage CloudStack - I have added some details here (https://cwiki.apache.org/confluence/display/CLOUDSTACK/Shared+NFS+Zone-wide+(primary)+Block+Storage) along with a JIRA ticket 724 Please review and comment
I've been thinking about this and IF we do this, shouldn't we make sure all primary storages are supported?
I'm also looking for a valid reason for doing this. Why not expand your cluster size?
Wouldn't doing this break the whole idea of zones, pods and clusters? Since they all share the same resources you can have multiple clusters going down (or even your whole zone) by just one component failing.
I know this is the responsibility of the guy who builds the CloudStack cluster, but still, why have more clusters when they share the same primary storage? You just add one SPoF spread out over multiple clusters.
