[Gluster-devel] excessive inode consumption in namespace?

[Anand Avati]

I'm having a bit of a puzzle here.

That is a bit of wrong math.

No of inodes in NS = No of directories in any child + No of files in all
children.
It is not directly proportional to any one child.

The namespace should be put on a partition where you can create LOT of small
files. Generally XFS or reiserfs will do a good job. If you are using ext3,
format it with a very small block size.

thanks,
