--------------------------------------

             Summary: Provide way to test MMap WAL modes failures
                 Key: IGNITE-8727
                 URL: https://issues.apache.org/jira/browse/IGNITE-8727
             Project: Ignite
          Issue Type: Test
          Components: persistence
            Reporter: Dmitriy Pavlov
            Assignee: Andrey Gura


Currently tests 4 are failed in  PDS 2 suite with timeout:
      IgnitePdsTestSuite2: IgniteWalFlushBackgroundWithMmapBufferSelfTest.testFailAfterStart (fail rate 100,0%)
      IgnitePdsTestSuite2: IgniteWalFlushBackgroundWithMmapBufferSelfTest.testFailWhileStart (fail rate 100,0%)
      IgnitePdsTestSuite2: IgniteWalFlushLogOnlyWithMmapBufferSelfTest.testFailAfterStart (fail rate 100,0%)
      IgnitePdsTestSuite2: IgniteWalFlushLogOnlyWithMmapBufferSelfTest.testFailWhileStart (fail rate 100,0%)

Tests tries to emulate failure using exceptions in file IO, but MMap-ed modes does not allow currently to be tested with current tests approach.

It is suggested to create new testing opportunities for MMap modes.
