When you run drain the node will log someone like "node drained" when it is

the system tables after the drain. Can you raise a ticket and include the
commit logs left behind and any relevant log messages?

in 0.8, it seems to contain 2 files, a 44 byte .header file and 270 byte
.log file. do these indicate a fully drained commitlog?
* i have a couple node
