RDS MariaDB: ERROR 1114 (HY000) at line LLL: The table 'XXX' is full

Question

I am trying to import a 3GB MariaDB dump into my RDS MariaDB db.t3.medium with 50GB storage,  
And I am getting this error:  
ERROR 1114 (HY000) at line 20546: The table 'mdl_question_attempt_step_data' is full  
(It is a Moodle LMS DB)  
  
I have imported several DBs before, with not issue. but they were smaller then 1GB.  
  
I am about to import a 50GB DB, and the RDS is set to "auto grow" the storage.  
Should I do any pre import preparations?

Answer

SOLVED  
It probably too the auto storage scaling process to run for some moments (or an hour?)  
And after I saw in the DB monitor that I have more free disk space, I ran the import command again, and... every thing finished successfully :-)  
  
This time, I was monitoring the progress via CLI  
pv ./moodledb.sql | mysql -h DDDDD.eu-west-1.rds.amazonaws.com -P 3306 -u XXX -p moodledb
