Rakesh R commented on BOOKKEEPER-199:
-------------------------------------
Thanks Sijie for the comments & time:-) Yes, I will put the re-worked patch in
the review board.

1) in BookieWatcher, if a bookie server is restarted (maybe by admin guys) from
R-O mode, seems there is no logic to remove a bookie from R-O mode to write
mode. do I miss something?
{quote}
I am keeping the r-o status in bookie's presence znode(which is emphemeral),
when restarting its creating new presence znode and like a normal r-w bookie.

One thing might be missed is that when a force flushing (ledger eviction
happened) failed, we might need to consider turning the bookie into R-O mode
too.

Hope you are pointing me to consider the ledger failures of 'SyncThread' ?
Also, I missed dealing the ledgerCache failures, it would be great to see your
thoughts/opinion ?
Thanks,
Rakesh

> Bookkeeper should change to readonly(r-o) mode when the journal/ledgers
> flushing has failed with IOException. Later on, reject write requests on
> server side and will accept only the read requests from the clients, because
> even if flushing fails, the data in the bookie which has been flushed is
> still valid.
