ASMCMD shows very less Free_MB than expected for DBFS_DG

Hello all,

After an upgrade to 19c, the asmcmd shows very less Feee_MB than expected for DBFS_DG.

State    Type  Rebal  Sector  Logical_Sector  Block       AU   Total_MB    Free_MB  Req_mir_free_MB  Usable_file_MB  Offline_disks  Voting_files  Name

MOUNTED  HIGH  N         512             512   4096  4194304    2422560       3348            69216          -21956              0             Y  DBFS_DG/

I don't think the diskgroup has occupied almost 2.4 TB of space, not sure where the remaining space is.

Thanks,
