APAR status

  • Closed as program error.

Error description

  • Reading directory using regular file read cause sparse
part of directory
block to become valid with zeros.   This lead to
mmfsstruct error during
later directory lookup.   Fix gpfsRead() to return
E_ISDIR
when called on a directory.

Local fix

  • 



Problem summary


    

  • Directory lookup failed with mmfsstruct error as result of
regular file read on a directory causing sparse directory

Problem conclusion


    

  • Fix file read code to prevent reading of directory as
regular file.
