Sorry about that, I suppose I should have mentioned that we are 100% external
redundancy.

You shouldn't be using free_mb - you should always be using usable_file_mb.
Otherwise, as soon as you're dealing with a diskgroup that's anything but
EXTERNAL redundancy, you'll be looking at the wrong numbers.

Here is the query I have wrapped with an asmdf shell script so I can just
type asmdf and get a report that looks similar to df with total, used, free

percentages if you wish.

Usable and free can vary if you have ACFS volumes defined. Maybe there are
other scenarios that will cause them to be different, but that’s at least an
example. If I wanted to know how much space I have available in terms of a
percentage, I’d go with usable/total.

Subject: figuring out space
So I’m using ASM and trying to create a report that alerts me to space
issues. Using gv$asm_diskgroup
I have total space, usable space and free space. It looks like usable and
free have the same value.
I’m trying to figure out a calculation that will alert me when there is only
about 30% left. For the life of
me, I can’t see to get the calc right. Help!!!!!
