Hello haoyang.wang,
I would call into support so that we can look into your system to see what all is going on.
Please let us know if you have any other questions.

inodes are dynamically allocated in Isilon, so you should never worry about inodes.

OneFS dynamically allocates new inodes from free file system blocks

The reporting of inode statistics to a NFS client via the df command has changed over various releases of OneFS, and also depends on quota settings. In your original example, the displayed inodes counts are huge, and obviously have nothing to do with the actual inodes in the files system.
As already noted, capacity for inodes is shared with file data capacity, so it is not possible to run out of inode space before file space is exhausted.
You might set up a small test folder with quota and export it, and try out filling it up with smaller or larger files to see how the df inode reports behave in your environment. In the end, this might help you to savely ignore your application's alerts; or possibly to adjust the alerting settings -- AFAIK ElasticSearch is somewhat configurable.
