  • 1.  Maximum number of files stored in a single directory

    How many files can be stored in a single directory? I would assume the limit for a current OS like AIX 5.2 is above 100,000?

    Is it only limited by the HDD size: HDD size / block size = max. number of files ?
    Or is there a limit for the i-nodes?

    inode allocation is dynamic, you are only limited by the size of the disk.

    For each file an i-node exists which keeps an primary key for this file. So if the number of i-nodes in JFS2 are only limited by disk space, consequentially the number of files is also limited by disk space. Is this right?

    yes, Each file and directory has an i-node that contains access information such as file type, access permissions, owner's ID, and number of links to that file.
