[Documentation](../../README.md#documentation) → Usage → NFS ----- [Читать на русском](nfs.ru.md) # NFS 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. vitastor-nfs usage: ``` vitastor-nfs [--etcd_address ADDR] [OTHER OPTIONS] --subdir
