acfsutil size: ACFS-03008: The volume could not be resized

          Error：

           acfsutil size: ACFS-03008: The volume could not be resized.  Either the  volume expansion's limit has been reached or ASM could not expand the  storage.

 

         Cause:

1. 磁盘组空间不够（一次至少调整256M）

2. 
   This error is caused by file system’s internal storage bitmap has a five extent limit.
   Growing the file system may fail if it has already been grown four or more times, using up all available storage bitmap extents.

   Solution:

   1.  /bin/umount -t acfs /datapump
   2.  /sbin/fsck -a -v -y -t acfs /dev/asm/acfsvol-303
   3.  /bin/mount -t acfs /dev/asm/datapumpvol-23 /datapump
