This sounds like one of two possibilities: 1) You aren't actually committing data to RADOS very often and so when the power fails you lose several minutes of writes. How much data are you losing, how's it generated, and is whatever you're doing running any kind of fsync or sync? And what filesystem are you using? 2) Your cluster is actually not accepting writes and so RBD never manages to do a write but you aren't doing much and so you don't notice. What's the output of ceph -s? -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
