DB2 Large Tablespace has one container that's exceed limit 4TB

Hi all,

I used DB2 11.1, and has application that created table with USERSPACE1 using large tablespace to store large table with LOB column.

Yesterday, I got this below message when try to insert new records:
MESSAGE : ZRC=0x8404000A=-2080112630=SQLD_RC_MAX_OBJ_SIZE
"ARCHITECTURAL PAGE LIMIT REACHED"
DIA8710E Maximum table size was reached.

As I investigated, I was found there is one large tablespace container file as below has 4TB.
F:\DB2\NODE0000\{DbName}\T0000002\C0000000.LRG

This Database has used Automatic Storage when created, and this tablespace is DMS.

I tried to add new tablespace container into this tablespace but unfortune there is this error:

DB2 ALTER TABLESPACE {TableSpace} ADD (FILE 'C0000001.LRG' 500G)

SQL20318N The ALTER TABLESPACE statement failed because the change is not
allowed for the type of table space. Table space name: "{TableSpace}". Table
space type: "AUTOMATIC STORAGE". Incompatible clause: "ADD". SQLSTATE=42858

How can I force this tablespace to create new container file to avoid used existing tablespace container that already exceeded 4TB limited file size?

Best regards,
DBA who was found nightmare. :p
