Share(testsamba) is owned by root. It cannot be exported via SFTP with root ownership

@Vardan_Harutyunyan Welcome to the Rockstor community forum.

Hopefully the following section in our official docs should help:

http://rockstor.com/docs/sftp/sftp.html

It give details of constraints that currently exist with regard to how Rockstor currently servers up sftp.

ie: in the section "The Rockstor SFTP System"
we have:

"The SFTP user must be a Rockstor user"
"The SFTP user must also be the owner of an exported SFTP share"

Hope that helps.
