You need to add disk to +DATA diskgroup to solve problem, or if you have chance to delete any files you should delete any files to allocate new spaces.
You can add disk to DATA diskgroup like below script.
ALTER DISKGROUP DATA ADD DISK '/dev/mapper/asmtsk1' NAME DATA_0002 SIZE 102399 M REBALANCE POWER 10;
