 # Test case describe: dnode1 is only mnode, dnode2/dnode3 are only vnode
 # step 1: start dnode1
 # step 2: start dnode2 and dnode3, and all added into cluster (Suppose dnode2 is master-vnode)
-# step 3: create db, table, insert data, and Falling disc into file (control only one file, e.g. 1841)
-# step 4: insert old data(now-20d) and new data(now-40d), control data rows  in order to save in cache, not falling disc 
-# step 5: stop dnode2, so date rows falling disc, generate two new files 1840, 1842 in dnode2
-# step 6: insert two data rows: now-21d, now-41d
-# step 7: restart dnode2, waiting sync end
