Hello,
I have installed Oracle Grid Infrastructure 19c on linux (stand alone). There is a mounted diskgroup called DATA.
And I have installed Oracle RDBMS and I trying to create a container database using dbca.
But I got errors. dbca log:

I don´t understand what is the problem here. The diskgroup is mounted.
Both oracle grid home and oracle rdbms home is owned by oracle user.
Please, could help me?
Thank you very much
