Recently I read about Bookkeeper fencing protocol. I didn't find the answer to my question in the protocol description so I'm asking here:
When the ledger is fenced, the bookies are instructed to not accept new writes, but to accept only recoveryWrites. For correctness this should be saved to a persistent storage. I expect that it is enough to save this info persistently at the bookie server. Am I right, does it work in Bookkeeper this way ?
