Error description

  • When new file system paths are added to the filesystem which
    already contains pre existing containers
    on the same file system path for the tablespace, the free space
    information from the file system is
    pulled, and translated into a path-specific information. For
    example, if 2 new paths are added to a
    filesystem which already had 2 pre existing paths for the same
    tablespace in the same filesystem, the new space estimation is
    calculated
    
    Total freespace / number of filepaths
    
    And hence in this case it would be,
    
    total freespace/4
    
    which is incorrect, as this check is neglecting the fact that
    only two out of these four paths are going to require
    the freespace for the container creation, and hence may result
    in SQL2094N
    

Local fix

  • create new container paths in different file system
