new ASM disk space not available?

Hello,

I'm working on a 12.1.0.2 RAC configuration where DATA diskgroup initial size was 300GB. I recently added disk space because the diskgroup was almost full (see process below)

[root ~]# oracleasm createdisk  T3DATA01 /dev/mapper/lun_rac03_data3

Writing disk header: done

Instantiating disk: done

[root ~]# oracleasm createdisk  T4DATA01 /dev/mapper/lun_rac03_data4

[root ~]# oracleasm listdisks
