Package vitastor-nfs: Information

Vitastor has a simplified NFS 3.0 proxy for file-based image access emulation. It's not
suitable as a full-featured file system, at least because all file/image metadata is stored
in etcd and kept in memory all the time - thus you can't put a lot of files in it.

However, NFS proxy is totally fine as a method to provide VM image access and allows to
plug Vitastor into, for example, VMWare. It's important to note that for VMWare it's a much
better access method than iSCSI, because with iSCSI we'd have to put all VM images into one
Vitastor image exported as a LUN to VMWare and formatted with VMFS. VMWare doesn't use VMFS
over NFS.

NFS proxy is stateless if you use immediate_commit=all mode (for SSD with capacitors or
HDDs with disabled cache), so you can run multiple NFS proxies and use a network load
balancer or any failover method you want to in that case.
