vger throws out all HTML email. Make sure you send in plaintext.
How do writes work in Ceph? If I open

See 'man cephfs'. This should probably go in the wiki too.

Let us say I have a random write workload. I want to write 100 blocks to
block X on replicas A, B and C. Let's assume that in replica C I wrote only
99 bytes and the replica crashes. How does it is correct itself?
The writes are applied atomically.
Yeah, I've got a few VMs set up to play with. Sort of painful having
multiple VMs write twice with the hard disk journal.
I'm certain now that I can duplicate this, so I'll start fresh again
once more and keep track of the steps.
Replying-all this time...
