Download Information: Version 8.1.6.2 Interim Fix: IBM Spectrum Protectâ„¢ Snapshot UNIX/Linux

APAR status

• Closed as program error.

Error description

• IBM Spectrum Protect Snapshot version 8.1.6.1 running on Linux
  for Db2, Oracle, SAP on Oracle or Custom Applications fails to
  freeze filesystems on Red Hat Enterprise Linux version 6 or 7
  and SUSE Linux Enterprise Server version 11 or 12. The following
  error message could be shown:
  09:31:06 FMM1200E Profile parameter 'LVM_FREEZE_THAW' is set to
  YES but freeze/thaw is not supported by the underlying file
  system.
  09:31:06 FMM9300E Additional support information: Aborting
  'send' operation. See previous error.
  09:31:06 FMM1255E The process cannot continue. Reverting
  changes.
  09:31:06 FMM9224E The operation will be aborted. Check for other
  error messages in the log files.
  
  If TRACE is enabled in the profile then the acsgen trace file
  will erroneously show that filesystem freeze is not supported:
  04:01:02.871      400 (7f21a821f700) esd-pythonobj.hpp:52
  ESD_PythonObj::getAttr: is_freeze_supported
  04:01:02.874      400 (7f21a821f700) esd-pythonobj.hpp:52  ...
  EXIT }
  04:01:02.874      400 (7f21a821f700) esd-pythonosadapter.cpp:398
  isFreezable=0
  

Local fix

• The only local fix is to disable freeze/thaw in the IBM Spectrum
  Protect Snapshot profile by setting LVM_FREEZE_THAW to NO. This
  may result in a so called 'forced mount' operation during a
  snapshot backup operation where the filesystem consistency will
  be verified by mounting the snapshot backup on a backup system.

Problem conclusion

• The identification of filesystem that are capable of freeze/thaw
  has been corrected.
