Server Administration :: ASM Diskgroup Resize?

I've been ASM quite a while. I've two diskgroups extdg and nordg which are of external and normal redundancy respectively. Total diskgroup size is 9G, usuable space came down to 3mb when i tried to resize it to itz maximum. the value under usable column shows the same.

FYI... i've totally three disks in nordg, two in one failgroup and one in another.The disk sized equally 3g each.

Quote:
NAME TOTAL_MB FREE_MB USABLE_FILE_MB
------------------------------ ---------- ---------- --------------
EXTDG 2047 1995 1995
NORDG 9201 3073 3

The command i used to resize all disk to their max is Quote:SQL> alter diskgroup nordg resize all size 3067M;
