Thanks for answer!
After adding the debug options I get next information:
------------
E n d   P r o c e s s i n g
#PETSc Option Table entries:
-ksp_max_it 10000
-ksp_monitor_cancel
-ksp_monitor_short
-ksp_rtol 1.e-12
-ksp_type gmres
-mat_mumps_icntl_14 25
-mat_mumps_icntl_22 1
-mat_mumps_icntl_24 1
-mat_mumps_icntl_4 0
-mat_mumps_icntl_7 4
-mat_mumps_ooc_tmpdir /home/vskych/11/
-mat_view_info
-options_left
-options_table
-pc_type lu
#End of PETSc Option Table entries
There is one unused database option. It is:
Option left: name:-mat_mumps_ooc_tmpdir value: /home/vskych/11/
Info    : Stopped (Tue Sep  3 13:00:31 2013, CPU = 89.148s, Mem = 664Mb)
--------------
And ooc option quoting gave the same result.
