I originally replied directly to Chris, who pointed out that the answer might be of interest to the mailing list.

The aggregate has a little file system inside to hold data related to the aggregate and the flexible volumes. There are two key files per flexible volume and 1 directory per flexible volume. In some cases (mirroring, flex cache, etc.) there may be an additional inode used per flexible volume. Typically the free inodes in the aggregate are never used and take no additional space.

What does the output of "df -A -i" mean for a non-traditional

aggregate?

For example:

...

df -A -i main

Aggregate iused ifree %iused main 108 31034 0%

Such aggregates always seem to have 30000+ "inodes", regardless of

size,

and to use 3 more each time a flexible volume is allocated inside the aggregate.
