Data catalog incorrect. no .ocdata file

Hi everyone! I’ve tried to install new instance of NC based on Ubuntu. Previous instance was on Debian, so I have some experience in troubleshooting and managing. But on Ubuntu I have 1 problem. After rebooting, I got error, that data catalog incorrect, please check the file “.ocdata”
I checked everything, configuration and data folders, everything right. Additionally I checked right to file.
Config file
'datadirectory' => '/datastore/NXTCloud/data/',
Files

 ls -al /datastore/NXTCloud/data/
