Hello,

I have a filesystem that will some addition space:

Filesystem                        Size    Used   Avail Use%      Mounted on

/dev/asm/datastore-397   200G  177G   24G  89%        /u01/app/oracle/oradata/datastore

I have another filesystem that has plenty to spare:

Filesystem                         Size   Used   Avail   Use%      Mounted on

/dev/asm/datastore-163    15T    2.0T    13T    15%         /u02/app/oracle/oradata/datastore

Both are running on an X5-2 ODA box and virtual 2-node RAC.

I understand that ACFS sits on top (or is made up of) asm diskgroups.

What I need to learn/understand is how to shrink the filesystem/asm group on /u02/app/oracle/oradata/datastore by 1Tb and then add that space to the /u01/app/oracle/oradata/datastore filesystem.

Howdy, Stranger!
