Hi,

Please take a look, this data remains for days and seems not to be
deleted in future too:

I have same thing before, but not so contrast as there. Cluster was
put on moderate failure test, dropping one or two osds at once under
I/O pressure with replication factor three.

Just wondering if there was something else you wanted to discuss on your email given the email subject. Wanted by any chance discuss anything regarding Paxos?
