diskgroup out of space

Hello Erman,

I noticed diskgroups are running out of space on Exadata.

ACFSC1 and DATAC1.

Should we add more disks to diskgroups? Is it same like adding adding disks to normal ASM diskgroups?

What could cause the high increase in space usage for ACFSC1?

Regards,
Roshan

I have checked.. the acfs filesystems have enough free space. Then why is the output negative?

Your concern seems to be the Disk usable file mb.
 
Well, we visit the MOS note named, "Understanding ASM Capacity and Reservation of Free Space in Exadata (Doc ID  1551288.1)" and have a look at the following as well; https://ermanarslan.blogspot.com/2020/09/asm-grid-my-thougths-on-15-free-disk.html
