[erlang-questions] Question about distributed mnesia behavior

[cao.xu]

Hi,

	I am using mnesia recently under OTP R15B, and feel confused about some behavior of distributed mnesia.

	I ran two nodes with sname 'test1' and 'test2', and then executed the following command "mnesia:create_schema(['test1', 'test2']), mnesia:create_table(test, [{disc_copies,['test1', 'test2']}]" on 'test1'. After that, I was able to use table 'test' on both nodes, everything seemed fine.

	 Then I shutdown these two nodes and restarted 'test2', the table 'test' was still accessible and I could read and write on it.  But when I shutdown 'test2' and restarted 'test1', the table 'test' was unaccessible. The function wait_for_tables would timeout and operations on table 'test' would fail. Only if 'test2' is running, the table becomes accessible again on 'test1'.

	I was wondering if this is an expected behavior, or the table should work properly on both nodes when they run alone.
