1. construct a probabilistic model for data loss in 1, 2, and 3 copy systems, assuming independent failures
2. plug in standard disk/ctlr/cpu/nic/unrecoverable read error rates

- Status changed from New to Closed
This bug has been judged too old to fix. This is because either it is either 1) raised against a version of Ceph prior to Luminous, or 2) just really old, and untouched for so long that it is unlikely nowadays to represent a live documentation concern.
If you think that the closing of this bug is an error, raise another bug of a similar kind. If you think that the matter requires urgent attention, please let Zac Dover know at zac.dover@gmail.com.
