Yes. The problem with permission. But not with permissoin on export directory. Two ways to resolve this: 1) Make 777 permission on directory - dont right solution. 2) anonuid=36,anongid=36 in export - this right solution, very strange that this is not in any documentation, but very important! I has right permission on my export directory, but this is not working before i mke 777 chmod. After i chande parameters in exports file i return chmod to 755 and all working fine now! Thank you and all very much.
