Ability to share a disk (assign disk to multiple virtual machines)
For 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).
That would be a welcomed feature. Cureently using SAN with NFS/iSCSI module for this. Not the best solution because it puts an extra strain on NIC-s.
