Re:[DISCUSS] markdelete position not moving forward when skipping lost entries

[lordcheng10]

Here I add, the scene of losing data at that time:
1. For the bookkeeper cluster, we turned off the journal writing function;
2. Then during the upgrade, after executing the stop command several times, the 
bookkeeper process does not exit, we will kill -9;
3. Kill -9 will cause the data in the cache to be too late to flush the disk;
4. We have two copies, if kill -9 twice in a row, it may lead to the loss of 
all copy data of an entry;
