APAR status

• 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.
