Hi, Nam, 

On the node that is reporting the LevelDB Manifest error, I would do the

1. Stop the node if it isn't down already. 

2. Backup
/var/lib/riak/leveldb/502391187832497878132516661246222288006726811648 to
another folder outside of /var/lib/riak/leveldb. 

3. Run the erl binary included with Riak (typically underneath
/usr/lib/riak/erts-*/bin or /usr/lib64/riak/erts-*/bin in Linux) to startup
an Erlang shell. 

4. Issue the following to open the node's LevelDB database: 
    [application:set_env(eleveldb, Var, Val) || {Var, Val} <- 
    [{max_open_files, 2000}, 
    {block_size, 1048576}, 
    {cache_size, 20*1024*1024*1024}, 
    {sync, false}, 
    {data_root, "/var/lib/riak/leveldb"}]]. 

5. Run 
    eleveldb:repair("502391187832497878132516661246222288006726811648", []). 

6. After the repair has completed, run 
   or hit ^c twice to exit the shell. 

7. Restart Riak. 

Let us know how this goes. If you run into any more trouble, ping the list
and we'll give you a hand!
