    The FS is a jfs2 with some sub-dir. On one sub-dir, I must create a huge number of subdir, each containing files and subdirs. On the first subdir, I have 79632 subdirs and I can't create any more subdir, only files.

    df output:
    /dev/MKSYSBCKP 218234880 44507568 80% 461941 9% /mksysbckp

    ls -l of FS content output
    total 125931528

    nbes is the problem!

    Error msg when trying mkdir
    There are too many links to a file.
    (find on dir nbes with -type l doesn't find any link!)

    Are they some limitations in number of subdirs on one directory?
    jfs2log has to play something?

    And I can do mkdir on same level as nbes, it works!
