I am sorry I have to tell you this, but after step one, knowing the
resize of the filesystem did not take place, you should have stopped.
lvreduce does not resize the filesystem! see man lvreduce:

So you have corrupted the filesystem and this is the time to restore
your backup. Or you can give "testdisk" a try, but not without
carefully reading the provided documentation! Actually I never needed
it, but the description states, that it can be of help in situations
like yours.
