Error description

  • Opening a file from a IBM Rational ClearCase dynamic view with
    O_CLOEXEC fails with an EINVAL error on IBM AIX 7.1 TL4 Service
    Pack 2.
    This is caused by the new O_CLOEXEC flag requiring 64-bit open
    flags and returning an EINVAL error for filesystems that do not
    support these flags.
    As MVFS doesn't inform the OS it can support 64-bit open flags
    the EINVAL error is received when opening a file with this flag.
    
    WORKAROUND:
    None.

    * On AIX 7.1, using the open() system call with the O_CLOEXEC  *
    * flag to open a file/dir in the ClearCase MVFS returns        *

Problem conclusion

  • On AIX 7.1 (and later) the O_CLOEXEC flag can now be used to
    open a file/dir in the ClearCase MVFS.  This problem is fixed in
    ClearCase fixpacks 8.0.1.14 and 9.0.0.4.
