Marton Elek commented on HDDS-4904:
-----------------------------------

Thanks to open this issue [~arp]. As it's an existing component I would rather 
extend the docs it instead of removing it. We can add highlighted warnings 
(like on in this page: 
https://ozone.apache.org/docs/1.0.0/feature/topology.html) to example the 
limitations.

I think it depends on from the use case what is "serious usage", and there 
could be use cases where existing solution may help (for example providing read 
only access to bigger files for further processing from conatiners) 

I would rather add a warning something like this:

{quote}
Ozone CSI support still in alpha phase and buckets can be mounted only via 3rd 
party S3 compatible Fuse implementation (like Goofys). Fuse over S3 can provide 
only limited performance compared to a native fuse file systems. Long-term 
Ozone may support a custom solution to mount buckets which provides better user 
experience (with fuse or NFS or any other solution). Until that CSI is 
recommended to use only if you can live with the limitation and your use case 
is tested carefully.

What do you think?

> The Ozone website prominently mentions CSI support:
> [https://ozone.apache.org/docs/1.0.0/]
> [https://ozone.apache.org/docs/1.0.0/interface/csi.html]
> Our docs give a false impression to users that CSI is fully functional and 
> supported for persistent storage inside containers.
> This support uses goofys+S3 gateway, so it is not appropriate for any serious 
> usage. A real CSI solution should use an approach like the cBlocks prototype 
> by building directly on top of HDDS containers with a real device driver.
> Until that time we should not claim CSI support. Alternatively we should be 
> honest with our users that it is a prototype and not suitable for serious 
> usage.
