Check ASM Diskgroup Space and Directory Size

The script below can be used to check the Disk Group Space Free and also Check Directory sizes for each Disk Group

The script is written by somebody at Pythian but i cannot re-collect the original link to the blog.

eg:
./asmcmd_du.sh

DiskGroup Total_MB Free_MB % Free
——— ——– ——- ——
DATAC1 15962112 11215880 70
DBFS_DG 415296 403740 97
RECOC1 3996000 3460272 86

./asmcmd_du.sh DATAC1

DiskGroup Total_MB Free_MB % Free
——— ——– ——- ——
DATAC1 15962112 10155732 63

DATAC1 subdirectories size

Subdir Used MB Mirror MB
—— ——- ———
CARATST/ 55646 111356
ECCTST/ 174912 349856
—— ——- ———
Total 2799978 5600788

Script Below :

  1. Thanks for the code Shadab.

    One thing you need to add here is to assign an initial value for SUBDIR value to satisfy IF CONDITION at the bottom of your code.

    1. Hi Hamid. As i wrote in my blog this is not my code but from the pythian blog. I just reformatted it a bit.
