  • Closed as program error.

Error description

  • The Spectrum Protect automatic deployment script for Linux
    relies on POSIXLY_CORRECT environmental variable in order to
    correctly interpret the output from `df` command. In case the
    variable is set but not exported, the script considers the
    output is in 512B blocks, but in fact df still reports the disk
    space in 1K blocks.
    
    In certain cases (when the available disk space is not twice as
    big as it is necessary for the client to upgrade) this can lead
    to an update failure.
    
    Platforms affected:
    All Linux
    
    Versions affected:
    All supported
    

Local fix

  • Unset the POSIXLY_CORRECT environmental variable or export it.

Problem conclusion

  • If POSIXLY_CORRECT variable is set but not exported the
    deployment script incorrectly estimates the free space on the
    destination disk. The code has been changed, so the script
    checks whether the variable is exported in order to correctly
    identify the measuring units of the free disk space.
