I went through LP-1464656 and I see that it covers two things:
1. Bad pg num calculation algorithm.
2. Add the possibility to set pg num via GUI.
First is the most important and a BUG by itself, second is nice to have
feature and no more.
Hence we should split it into a bug and a feature.
As the main part is a bug it does not impact FF at all.
My +1 to close bad pg num calculation algorithm as a bug and postpone
specifying pg_num via GUI to the next release.
/All the best
+1 for FFE
Given how borken pg_num calculations are now, this is essential to the ceph
story and there is no point in testing ceph at scale with out it.
The only work-around for not having this is to delete all of the pools by
hand after deployment and calculate the values by hand, and re-create the
pools by hand. The story from that alone makes it high on the UX scale,
which means we might as well fix it as a bug.
The scope of impact is limited to only ceph, the testing plan needs more
detail, and we are still comming to turns with some of the data format to
process between nailgun calculating and puppet consuming.
We would need about 1.2 week to get these landed.
