Unable to CREATE DATABASE: error while processing file dmanage.bsq I want to create a DATABASE on my recently installed Oracle 12c so, after creating spfile and listener/tnsnames/sqlnet.ora for my instance, I call my CREATE DATABASE request :

CREATE DATABASE DBNAME
   USER SYS    identified by password
   USER SYSTEM identified by password
     MAXINSTANCES  1
     MAXLOGHISTORY 1
     MAXLOGFILES   20
     MAXLOGMEMBERS 4
     MAXDATAFILES  200
   CONTROLFILE REUSE
   DATAFILE
           '/[...]/system_01.dbf' SIZE 1000M REUSE
   EXTENT MANAGEMENT LOCAL
   SYSAUX DATAFILE
           '/[...]/sysaux_01.dbf' SIZE 2000M REUSE
   UNDO TABLESPACE "UNDO" DATAFILE
           '/[...]/undo_01.dbf'     SIZE 2000M REUSE
   DEFAULT TEMPORARY TABLESPACE "TMP" TEMPFILE
           '/[...]/tmp_01.dbf'       SIZE 2000M REUSE
            EXTENT MANAGEMENT LOCAL  UNIFORM SIZE 1M
   LOGFILE
       GROUP 1 ('/[...]/redo_1a.dbf',
                '/[...]/redo_1b.dbf') SIZE 100M REUSE,
       GROUP 2 ('/[...]/redo_2a.dbf',
                '/[...]/redo_2b.dbf') SIZE 100M REUSE,
   CHARACTER SET WE8ISO8859P15
   NATIONAL CHARACTER SET AL16UTF16 ;


And I get this error:

CREATE DATABASE DBNAME
*
ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced

The request at the line 22 of the dmanage.bsq file is:

CREATE TABLESPACE sysaux DATAFILE "D_SXFN"
  "D_SDSG" ONLINE FORCE LOGGING
/


What is the problem with my request?
According to this thread, this error means I don't have enough space on my disk. I try the same request with lower size for my datafile and it works.

So, I have two solutions: adapt, in my request, the size of my datafiles or extend my logical volume.
