PFS from INODZ

PFS will have 2 main modules.....
1. Pool manager
2. File system.

* Pool manager is the one tat should replace the volume manager.
The Pool Manager should handle multiple disks as a single logical pool. the size of that logical pool should not be limited. the size should grow when another disk is added to the pool, it should decreased when a disk is removed.! It should provide various functions to the file system tat will be sitting above this.

* the File System - PFS is the one tat interacts with the Pool Manager to get the data written into the hard disk. For this, the FS makes use of the methods provided by the pool manager. This interacts with the upper level layers like system calls etc.
