Hi,
another shameless plug: I wrote an article about the OSD Journal:
http://irq0.org/articles/ceph/journal
It focuses on the "How?" with some pointers to the code.
I hope someone will find it useful. Feedback is greatly appreciated!

It's very very nice article. I didn't known about "nojournal" feature.

To the best of my knowledge, no, "nojournal" isn't an alternative. In nojournal mode transaction commit acknowledgements are fired after a sync of the data disk. Meaning every 0.01 - 5 seconds in bulk. ~marcedl -- Marcel Lauhoff Mail/XMPP: ml@irq0.org http://irq0.org ^ permalink raw reply [flat|nested] 3+ messages in thread
