The following tests in the testsuite have race conditions: 1) Test that the primary mirror image cannot be removed while the mirror set is sync'ing. 2) Test that you cannot start a second mirror up-convert while one is already in progress. The trouble is that if the sync/conversion finishes before the tests occur, the tests will fail by why of success where there should have been failure. This means the sync/conversion must happen very quickly, but this is possible because the test mirrors we are creating are so small. In order to decrease the likelyhood of these test failing (or more correctly, failing to test the right thing), I've increase the size of the mirrors. It will still be remotely possible that the tests will fail (by way of failing to test the right thing). If this continues to happen, more involved mechanisms will need to be put in place. (Perhaps these will still be created, but this change should be a remedy until that time.)

Disallow the primary mirror image from being removed when the mirror is not in-sync. This restriction is not extended to repair operations (i.e. it will not limit what 'lvconvert --repair' can do).
