Description Andrea Perotti 2017-05-29 16:36:16 UTC
Description of problem:

In chapter "5.2. Erasure Code Profiles" of Red Hat Ceph Storage Guide

https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html-single/storage_strategies_guide/#erasure_code_profiles

is reported an example for the creation of an erasure code profile of 3+2, but at the time of writing the closest config supported is 4+2 (ref: 
* https://access.redhat.com/articles/1548993
* https://access.redhat.com/solutions/2094441 )

Is expected that documentation do not offer examples of unsupported configuration, and even if the future will expand the supported configuration, would be better to show safest examples from a supportability PoV.

Comment 3 Tupper Cole 2017-11-08 21:51:36 UTC
By the same token- should the default EC profile be a supported profile rather than k=2 m=1?

Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate.
