Ability to share a disk (assign disk to multiple virtual machines)
PlannedFor cluster environments we need to have the ability to share file system partitions between nodes within a cluster.
We currently work around this issue by creating a separate virtual machine which exports an iSCSI device. This device is then mounted on each node using OCFS2 on the iSCSI target.
This setup does not provide optimal performance. We would like to have the ability to create a virtual disk within OnApp which we can assign to multiple virtual machines directly.

We would use this in combination with OCFS2 or GFS2 to share data in cluster environments for large website. Files that would be shared are the core files of a website (e.g. large Magento online shops) where multiple front end nodes would need access to the same files (also images).

I would like something like this as well, which I requested here:
Including a block level storage driver that could mount a path right to the storage API and use a virtual disk in onapp IS for storage just like a VM does but without the need for a VM.
